Summary
👤
Senior🎓
Top SchoolAndrei Andriushchenko is a Senior Software Engineer with over a decade of hands-on experience building and rescuing backend systems for high-throughput, mission-critical applications. He specializes in performance tuning, large-scale refactoring, and designing resilient microservices using Python ecosystems (Django/DRF, FastAPI, Tornado) and data stores like PostgreSQL, Redis, and ClickHouse. His work spans fintech and security domains, where he has shipped from-scratch internal platforms—antivirus testing pipelines, rules and signature management services, and metadata/authorization systems—while also stabilizing legacy message pipelines under heavy load. Colleagues rely on him for pragmatic instrumentation and operational practices (including regular on-call rotations) that reduce incidents and materially improve response times and server load. Based in Haarlem, he pairs strong systems thinking with a track record of turning messy legacy codebases into maintainable, observable services.
