I build high-load Python and Go backends that deliver major performance gains at scale.

At CodeScoring, I led performance-critical backend work for SCA and OSA products, processing large-scale code analysis workloads with Python, Go, Django, FastAPI, PostgreSQL, Redis, and Celery. I rewrote the policy evaluation engine in Go to run up to 32x faster on enterprise repositories.

Previously, I scaled Forkway’s learning platform to 5,000+ concurrent users with sub-200ms latency and built iGaming services at re:Bot for 100,000+ active users. I enjoy turning complex product requirements into reliable architectures, efficient databases, and production-ready systems.
