## About

```text
At Deutsche Bank, I optimized a heavy HTTP request from 6 minutes to 20 seconds using multithreading. I also increased unit test coverage from 15% to 92% and improved Kafka consumer performance, with p95 latency under 150ms.

At MediaMarkt, I reduced API response time by 35% with Redis caching and full-text search, and led the migration from RabbitMQ to Kafka. I also automated releases with a GitLab CI and Docker pipeline.

At SHELL, I automated sick leave and vacation notifications, reducing application processing time by 30%, and built test analytics with per-topic percentage reporting. I work primarily with Java and Kotlin, and have experience across backend services, databases, and CI/CD.
