About Me

I am a Senior Backend Engineer with 18 years of experience building and operating enterprise-grade backend systems, primarily in financial and banking environments.

My focus is on designing scalable microservice architectures, running reliably in Kubernetes/OpenShift environments, with strong emphasis on performance, stability, and long-term maintainability.

I value clean architecture, pragmatic engineering decisions, and production-grade quality over hype.

Core Expertise

  • Java / Spring Boot
  • Microservices & Distributed Systems
  • Event-Driven Architecture (Kafka)
  • Kubernetes / OpenShift
  • REST APIs
  • Oracle (data modeling & performance tuning)
  • CI/CD & automation
  • Production performance optimization

What I Care About

  • Building systems that survive real production load
  • Reducing operational complexity
  • Clear service boundaries and maintainable code
  • Observability and measurable performance
  • Engineering over buzzwords

Currently

Working in a complex banking environment in Switzerland, focusing on backend services and distributed architectures.
