Lucian Marin is a Senior Python Developer based in Bucharest with 14 years of experience building production-grade backends, CI/CD pipelines, and data-driven systems across automotive, payments, cybersecurity, and ad-tech. He specializes in modernizing legacy stacks—recently migrating a C++ pricing platform to Python, Flask/FastAPI, Celery and containerized databases—and has built release and test automation frameworks that scaled QA from manual to fully automated. Comfortable across the full stack, he blends Python, JavaScript (React/Node), SQL/NoSQL, and DevOps (Kubernetes, Docker, Jenkins, AWS) to deliver reliable, observable services. At Secureworks he designed real-time incident detection APIs and multiprocessing automation for security teams, and at ChargeAds replaced a Hadoop pipeline with ClickHouse for real-time reporting. Creator of Subreply, he likes building small, focused social tools that punch above their weight, reflecting a pragmatic approach to product-minded engineering.
