Hi! I’m a freelance/contract-based Java developer who helps teams deliver clean, reliable software – the kind that’s easy to maintain, performs well, and doesn’t fall apart under pressure.

I’ve been building backends, APIs, UIs, and cloud infrastructure for several years. These days, I focus on projects where code quality, scalability, and real-world usability matter.
I can work hybrid in german-speaking switzerland or remote, and I’m open to collaborations worldwide.

☕ Java – My Core Stack

Java is where I’m most at home. I’ve worked with the language through many of its evolutions — and I keep up with new features all the way up to Java 24.

What I bring to the table:

  • Solid experience with modern Java: Records, Pattern Matching, Virtual Threads, Sealed Classes, etc.
  • Strong testing mindset: JUnit 5, AssertJ, Mockito, and Testcontainers
  • I practice TDD when it makes sense – not as a religion, but to keep code focused and testable
  • Familiar with patterns like Clean Architecture and Hexagonal Design (without overengineering)
  • I like Domain-Driven Design – especially when working on complex business logic
  • I’ve used a lot of classic patterns (Strategy, Specification, Builder, Visitor etc.) when they help keep things clean

🌱 Spring Boot & Ecosystem

Most of my backend work is based on Spring Boot or JavaEE/Jakarta – whether it’s building APIs, handling business logic, or integrating external systems.

What I usually work with:

  • Spring Boot (2.x / 3.x), Spring Security, Spring Data JPA
  • Flyway, QueryDSL, OpenAPI/Swagger, Actuator
  • Reactive services with WebFlux (when needed)
  • Modular monoliths or microservices – depending on what the project really needs

🌐 Frontend: Angular & Vue.js

While backend is my main focus, I’ve also built and maintained plenty of Angular and Vue.js frontends – mostly as part of full-stack projects.

  • Angular (strong TypeScript, RxJS, forms, routing)
  • Vue 2 & 3 (clean, component-driven architecture)
  • REST integration, state management, and UI frameworks like TailwindCSS

☁️ Cloud, Containers & DevOps

I’m comfortable building and deploying systems in the cloud – and I understand how to run things in production.

Tools & platforms I’ve worked with:

  • Docker, multi-stage builds, slim images
  • Kubernetes, health checks, Helm, namespaces, scaling strategies
  • OpenShift – often in enterprise settings
  • AWS – EC2, ECS/EKS, RDS, S3, IAM, CloudWatch, API Gateway
  • CI/CD pipelines with GitHub Actions, GitLab CI, ArgoCD

Whether it’s a lift-and-shift or cloud-native setup, I can help get things running smoothly.

⚙️ Performance & Code Quality

I enjoy digging into tricky performance issues – especially when things “almost work” but still feel slow or flaky.

Here’s what I typically do:

  • JVM profiling with JFR, VisualVM, or YourKit
  • Optimizing database queries and indexes
  • Improving memory usage and GC behavior
  • Frontend performance: bundle sizes, load time, LCP, etc.
  • Add automated checks to CI (tests, code quality, metrics)

🤝 How I Work

  • I work either hybrid oder remote near Zürich, Switzerland
  • I can work either on-site/hybrid in german-speaking switzerland or fully remote globally
  • Open to collaborating globally, async or real-time
  • I’m fluent in german (mother-tongue) and english and I understand swiss german very well
  • You’ll get clean code, honest communication, and practical results
