At Giga Ltd, I built a concurrent Go flight search engine that queries airline providers in parallel and streams results in real time, cutting complex search response times from around 10–15 seconds to about one second.
I also redesigned voucher allocation and top-ups to address race conditions and database-lock bottlenecks across 400+ resellers and 300K+ orders. The updated allocation logic guarantees exactly-once issuance.
At Giga Ltd, I built a Laravel and Filament reseller platform and developed Django microservices to decouple billing. I also integrated Zoho Desk ticket routing and mentored junior developers.
Previously at TechLines for Telecom & IT LLC, I optimized MySQL schemas and maintained Laravel server-side rendering features. I also built a side-project multiplayer chess platform with Go, WebSockets, Redis-backed matchmaking, and Stockfish-powered analysis.
