I'm a backend engineer with 6+ years of experience building scalable, high-availability production systems using Java (Spring Boot) and Python (FastAPI, Django). I design and deploy microservices, champion Docker/Kubernetes on AWS, and model data with PostgreSQL and Oracle SQL for financial and telecom domains. Lately I’ve specialized in AI-enabled backends, integrating LLMs and RAG pipelines for automation, and I’ve improved CI/CD processes to shorten release cycles. I have an EU work permit, fluency in English, and I’m actively learning German to advance to B1/B2 in 2025.
