Summary
🤩
Rockstar🎓
Top SchoolAmir Hosseininasab is a software engineer and Teaching Assistant with eight years of hands-on experience building high-performance backend systems in Python and Go. He has driven production-critical features like a dynamic pricing engine with 1400+ rules and a real-time gRPC reverse proxy, achieving sub-10ms responses and serving large mobile traffic. Equally at home breaking systems as building them, he’s pursuing an MSc in Computer Security at VU while actively competing in CTFs and hardening microservices against subtle bugs that once recovered 0.1% of revenue. His open-source work includes optimizing a proxy-scraper—refactoring for clarity, adding asyncio and multithreading, and improving observability—to make scraping both faster and more maintainable. Past roles span full-stack startup leadership, DevOps and mentoring, plus research work on random sampling designs, giving him a rare mix of product, performance and research sensibilities. Based in Diemen, he combines competitive programming roots and practical engineering to ship reliable, auditable systems.
