About

I build backend systems that need to be fast, reliable, and maintainable at scale. Currently at Satispay. Previously at Cy4Gate, where I designed SIEM systems processing 10,000+ events per second and modernized CI/CD pipelines for 18+ microservices — transitioning from legacy Java/Maven builds to containerized Docker solutions. I care about clean architecture, thoughtful testing, and systems that don't wake you up at night. Technologies I work with: Java (8–21), Kafka, Elasticsearch, Kubernetes, Docker, AWS, MongoDB, GitHub Actions
