01 — ABOUT

Professional Narrative

Backend Engineer and AWS cloud architect with 3+ years of experience designing and shipping production systems. I specialize in Python, Django REST Framework, FastAPI, and serverless architecture on AWS — building systems that handle real scale, from 50+ Lambda functions to PostgreSQL databases serving thousands of daily users.

My work spans the full backend lifecycle: architecting cloud-native solutions with Lambda, DynamoDB, Step Functions, and API Gateway; optimizing PostgreSQL performance through query tuning and Redis caching; and automating deployments with GitHub Actions and AWS CodePipeline. I care about infrastructure as much as application code.

Currently engineering backend systems at TimesTX GmbH (Germany) for a global course search platform serving international students. Open to remote backend engineering and cloud architecture roles.
