What I'm looking for

I seek backend/platform roles where I can build secure, observable, high-throughput cloud-native services, mentor teams, and deliver measurable business impact.

I am a senior Cloud-native Java engineer focused on building reliable, scalable insurance and fintech backends using Java 17, Quarkus, Jakarta EE and Spring Boot. I automate complex underwriting and claims workflows with Camunda, and obsess over clean architecture, performance and measurable outcomes.

At tech11 GmbH I automated underwriting and claims workflows, reduced turnaround by 50–60%+, implemented multitenant insurance modules with strict tenant isolation, and improved observability with Prometheus/Grafana/Loki/Tempo to shorten time-to-diagnose and prevent regressions.

I have shipped production REST APIs and payment aggregator services, mentored interns, and hold an OCP Java SE 17 certification; I thrive in cross-functional teams delivering secure, observable, high-throughput services on Docker, Kubernetes and AWS.
