Hi my name is Ko Turk and I am a Senior Java / Kotlin Developer at Blue4IT. I am working as a Fullstack engineer at the Rabobank, creating features in Kotlin and doing some Typescript ;).
As a speaker I like talking at international conferences and JUGs about Micrometer / Kafka and Kotlin! Best seen talk?! All talks with live coding in it! So that’s the reason that I’m trying and doing it more often! 😉
I hope you can appreciate! If you have some questions, don’t hesitate to contact me through Twitter (@KoTurk77).
Own your Software by using Micrometer and Spring Boot [LIVE CODING]
Imagine that you’re part of a (car) race team. You’re the one behind the screens to control the race and make some tough decisions (like changing the team’s strategy). But you don’t have the insights (or metrics) about your car, opponents, or even the weather. Sounds painful right? But why are we making this mistake when building our software? Why don’t we own our software by adding those insights (or metrics) by default?
SLFf4J logging is one side of the story, but we also need to know our application health. That’s where Micrometer comes in! It’s a library that you can use to define your own custom metrics, like:
- timers (to check the performance of your microservices)
- counters (to check how many times a certain event is occurring)
- gauges (to check the current value of a variable)
- and many more
These metrics are exposed by REST endpoints (JSON) together with Spring Boot actuator, which can be saved into a database like Prometheus or Graphite. And to visualize the data you can use a tool like Grafana. Pretty interesting right? In the demo (live coding!) I will show you how to create such applications using Micrometer, and Spring Boot.
Ready to win this race with me? Jump in!

Writing docs in your IDE – an AsciiDoc primer
Follow the documentation-as-code approach: Write documentation in your IDE, collaborate with other developers and writers using version control and let a continuous integration server scrutinize and publish your docs.
AsciiDoc is a lightweight markup language that translates for example to HTML and PDF. In a development environment, an IDE plugin provides editor support and preview pane.
Participants work in small groups using a web-based collaborative editor or their local IDEs. With small katas they will learn how to format text, structure documents, use images and embed diagrams. The workshop closes with a Q&A session to share best practices that participants can apply to their projects.

Design for GitOps: What have we learned from Everything-as-code at scale?
Learn about Everything-as-Code approach from our experience to enable effective and successful collaboration between hundreds of engineers by GitOps approach. In this session, I on-board you to “as-code” and GitOps practices and I share how have we married them to build “infrastructure-“, “observability-” and “permissions-“ as-code services. I will give you tips on how the system should be designed to help you start with GitOps quickly.
Everything as Code is the practice of treating all parts of the system as code. This means, storing properties of your system along with its source code in a repository such as git. When we additionally apply GitOps practices – we get a single-click automation backed by review, dry-run workflow and auditing for free!
How have we applied GitOps in our company?
In Dynatrace, more than 1000 devs across multiple locations and timezones collaborate every day. Automation is key to support fast-paced innovation. We’ve started from a hackathon to build first version of project Monaco (aka MONitoring As COde) – where we essentially automate observability as code. Then, we realized we can apply same approach to any area – for instance by “permissions-as-code”, anyone and anytime can elevate their permission to access new services by submitting just a pull request.
How can I start with GitOps?
The most important enabler for GitOps is proper RESTful API. We’ll go through most important guidelines on how API should be structured. Then, I will teach you how a basic GitOps workflow looks like. Finally, based on open-source project Monaco, we’ll learn that applying a state from the repository can be easily achievable.
I’m sure that after this session many of you will be inspired that your team and maybe even users of your platform can unleash unprecedented power of automation and effectiveness.

Running and monitoring a low maintenance Java web application
Have you ever organized a conference? Attendees, speakers, visitors and organizers expect a website along the conference.
What started as a built vs. buy decision, ended pretty quickly on the build side, despite having only a few weeks until the conference starts up. How customized should it be? What features are needed? In this talk we will start with an empty application, evaluating technology backend choices like Java, Javalin, Pac4j and templating languages, then go to planning the functionalities like not storing any login information as well as feature planning up to running in production. Do we really need a SQL data store or can we use the existing API for the session submission? We will cover downtime free rollouts as well as integration of APM to figure out issues while running the application.
Of course we will cover the holy grail: the possibilities of a halfway decent frontend for backend developers.

The team with 30 million players: Reducing software vulnerability at a global scale
Facing a global pandemic has been (and continues to be) an incredibly challenging period. There are very few people who have not seen dramatic impacts on their lives as a result.
While we as humans have been facing this struggle, a similar problem has been emerging in our software development community. Not only are we finding more vulnerabilities in our software than ever, but those weaknesses have been affecting a larger proportion of our software ecosystem.Are there lessons we can take from the last few years and the changes we have made to protect people from a pandemic and apply them to our software ecosystem? I believe there are.
In this talk, we will look at how the relationships between software projects improve our world whilst also making us vulnerable. We will do this by diving into the structures between codebases and looking at how these affect the risk faced by our people, data, and systems.

FIDO2/Webauthn: Replace passwords with strong phishing free security
The end of password-based authentication is near. Weak passwords are the cause of endless security breaches, and the constant reuse of the same password across different accounts is what keeps the clock ticking for the next breach to happen.
The FIDO2 standard aims to replace passwords entirely, and there is a good deal of chance that it will succeed. It has gained significant momentum in the past couple of years, as all major browser and operating system vendors fully jumped on board.
This talk will provide a deep dive of the FIDO2 and W3C WebAuthn standards, with the main focus on how to quickly implement it on any application using open-source FIDO Alliance conformant libraries.
Best practices, including security token lifecycle management, will also be covered.

Utilizing gRPC – an efficient communication mechanism for distributed applications
gRPC is a modern, high-performance framework that evolves the age-old remote procedure call (RPC) protocol. In cloud-native applications, we often work across programming languages, frameworks, and technologies. This interoperability complicates message contracts and requires great effort for establishing efficient cross-platform communication. gRPC provides a “uniform horizontal layer” that abstracts these concerns. Developers code in their native platform focused on business functionality, while gRPC handles communication unification.
In this session I will give you an overview of the gRPC, why and when to use it and why we have chosen it for mission critical applications. You will find out the benefits and drawbacks of this solution and in the end we will have a glimpse of what the future of gRPC will look like.

Mobile apps have become very popular in the past 10 years and a lot of companies are developing mobile apps or even basing their business around the mobile applications. However there is more than one operating system that runs on mobile phones – the two mostly used ones are iOS and Android. This would typically require building two separate mobile applications. A number of frameworks have emerged with the aim to simplify the development and minimize the cost and burden of building two separate applications – such as ReactNative, Flutter and others, all of which have their pros and cons. Kotlin Multiplatform is an emerging new technology aiming to approach the mobile application development from a different angle. We will showcase what the technology is about and why we think it has a unique advantage in specific use cases compared to the other Multiplatform solutions.

We are living in a world where modern applications are consistently moving towards microservice-based architecture. Thus, internal service communication is becoming a vital part of any system. Whenever we are not careful, our system can turn into a distributed monolith and this is the worst case. And of course every developer option when it comes to microservice communications is REST, we will go over event driven architecture as a solution and dive into the pros and cons of this popular architecture, some of the key design choices it entails, and common anti-patterns.
I’m a software engineer with more than 10 years of experience. I’m currently a Staff Software Engineer at Tide. I’m interested in Microservices, Event-Driven Architectures, DevOps and organizational scaling.
At Tide I’ve witnessed our engineering organization more than double in size in the past year, which allowed me to see first-hand what policies enable such rapid growth.
Before Tide I spent around 8 years working in the Gambling Industry. Software systems in that industry usually process millions of financial transactions per day, being subject to even higher peak loads during sporting events and certain holidays. This has allowed me to gain experience designing and developing Software that possesses the required Availability, Performance, Throughput, Observability, Scalability, etc.
Technical Excellence at Scale
The talk will focus on the importance of knowledge sharing for promoting Technical Excellence at Scale. This topic has always been relevant for bigger organizations, while smaller ones have usually relied on Tribal Knowledge. But in today’s world we often see successful start-ups experiencing rapid growth – starting with just a small team of engineers and ending up with hundreds of engineers in just a few years. Imagine your engineering team doubling or tripling in size in a year or just a few months and a few of your initial key engineers leaving during that same period. How do you handle that without sacrificing the quality of your Software Delivery? One of the keys is, you guessed it, organizational policies that enable effective and efficient knowledge sharing which in turn promotes Technical Excellence. This is crucial for scaling your organization successfully. At Tide we’ve seen our Engineering Team more than double in size in the past year. Based on our experiences I’ll discuss what we’ve learned about policies and practices that do NOT scale well and ones that DO scale well as the organization grows. The talk will try to answer the following questions:
- Why Tribal Knowledge doesn’t scale well?
- What is “The Bus Factor”?
- Why does your Organization need Software Engineering Principles?
- Why does your Organization need Guidelines?
- Why do you need to automate them?
- What is Chesterson’s principle?
- How to create documentation that would allow readers to understand decisions made years ago?
- What is LADR?
- How can you automate documentation creation? (Open API, Async API etc.)
- Why does your Organization need a structured process for onboarding new engineers?
- Why does your Organization need Induction Sessions?
- Why are Code Reviews important for Technical Excellence?
- Why does your Organization need a Service Catalogue? (Backstage etc.)
- How do you handle Deprecation?
- Why does your Organization need Interest Groups?

Workflow engines: The missing piece
With the prevalence of microservices, whole architectures are cut into smaller pieces that are loosely coupled. Useful business processes typically span more than one service, though. In this talk I will discuss what does this mean for your architecture and the role a workflow automation technology can play within it. We’ll discuss visibility/orchestration of cross-microservice flows, error monitoring, compensating transactions, and more.
DDD and JPA: Proceed with caution
Domain-driven design promotes the use of a rich domain model, as opposed to an anemic one. However, mapping potentially complex value objects, entities and aggregates to a relational database can be a challenge. In this talk we’ll see how this can be tackled with JPA, what are some problems and limitations of the approach, and discuss several alternatives.

Now working to enlighten and education developers on software safety in all its guises. A seasoned speaker and regular presenter at international conferences on technical and software engineering topics.
Practical steps for creating safer software (Code included)
The world runs on software: we all know that but so do the bad guys. Now, more than ever before, understanding your role in designing, building and deploying safer software is critical. In this session I’ll take you through the basics. Learn the three principles of software design specifically aimed at creating more secure and robust solutions. From code to deployment to production there are steps you can take to keep the cyber-attacks at arm’s length and reduce the impact when something bad happens. It’s not all the problem of the developer but we have a crucial part to play in tackling cybercrime. That needs us to understand how our actions help or hinder both the bad guys and the others involved in the software lifecycle. This session will show you a little of how attacks happen, what’s out there to help with the defences and how your coding and design approach can make things worse or, hopefully, so much better.

API-first! Contract-first! Make API development great again!
In the current situation of increased remote working, having a common, easier to understand medium of communication such as an OpenAPI spec document is indispensable.
Things get exciting when this so-called OpenAPI spec document can help you build APIs and AUTOMATICALLY VALIDATE YOUR APIs! An OpenAPI spec document can also serve as a contract, generate clients, servers, documentation, and much more…
When this OpenAPI document can also:
- Put your developers, clients and client’s developers first!
- Have Automatic, Fail-fast, API Contract Validation!
- Be Cross-Platform and Language Agnostic!
- Generate clients, servers, and documentation from OpenAPI specs in a plethora of languages!
- Simplify communication by means of a common document in YAML or JSON!
- Speed up development, prototyping, R&D, etc.!
- Reduce costs! Using contract tests in conjunction with (or as a replacement for) traditional end-to-end integration tests will be cheaper in the long run.
… things get even more interesting in the demo…
Come at our talk and find out more!

Rise of captain hindsight: Finding Log4Shell with CodeQL
CodeQL is a free and powerful static analysis tool to look for vulnerabilities in OSS projects. It is commonly used to detect known vulnerability patterns and their associated variants in code. CodeQL queries are usually aimed towards very specific vulnerabilities for variant analysis purposes and are often integrated into CI/CD pipelines to automatically detect bugs. For this reason, CodeQL is configured to operate in a developer-first mode which will reduce false positives to a minimum and return the most accurate results. However, CodeQL can also be configured to operate in a less conservative, more security researcher friendly mode which results in more false positives but also less false negatives.
In this talk, Alvaro Muñoz of the GitHub Security Lab will use Log4Shell to demonstrate CodeQL in action. He will review Log4Shell’s root cause, how it manifests in code and how it could have been discovered using CodeQL. In this process he will discuss some specific examples of what it means to operate on each of the above-mentioned modes and how someone could configure CodeQL to better serve their objectives, either as a security researcher or a developer.

Evolving with Java – How to Remain Effective
Take Control of your Integration Testing with TestContainers
How easy is it to write and maintain integration tests when your system under test interacts with databases, message stores, and other external systems? It can be quite challenging, can’t it? For example, the lack of control over the setup of databases can increase the cost of integration testing. Sometimes we take the route of using an in-memory database instead of the one we employ in the production environment, making the tests less effective. With Docker containers, you can simplify this to some extent by running the setup before invoking your tests. Imagine if you get to control the database environment right from within the test code. TestContainers bring in this convenience.
TestContainers is a tool that you can invoke from your test code. It provides lightweight, throwaway instances of common databases, web browsers(Selenium tests), or anything else that can run in a Docker container. In this presentation, I walk you through how TestContainers is the most effective way to take advantage of Docker containers for integration testing. I present through several use-cases and demonstrate how TestContainers simplifies integration testing.

Future vehicle will run on AIoT
“Once, software was a part of the car. Now, software determines the value of a car. The success of a car depends on its software much more than the mechanical side.” – Manfred Broy, TU Munich. Many car drivers expect their vehicles to be fully integrated into their digital lives. In addition, new connectivity, automation, and personalization features will be increasingly implemented with software in the future. While in the past the customer’s experience of a car was primarily defined by hardware, data and software is now taking on a much more important role. This trend of software massively shaping the customer experience and, in some cases, even the specification of the hardware is referred to as the “software-defined vehicle”.
This evolution not only affects development and operation, but also makes new business models that rely on emerging AI and IoT technologies. So new types of collaboration are possible. German auto industry top managers always proudly stated that they have “gas in their blood”. But do they have electricity and code in their blood?
In 2025 all Bosch products either possess intelligence themselves, or AI will have played a key role in their creation. It is intended business to be more data driven and digital analytics to be used as a base for many decisions.
I will dive into the reference architecture for software defined vehicle platform developed jointly with Microsoft. I fully support that the automotive and IT industries do not have to be competitors. More than ever, they will complement each other.
