At Synegrow, I developed a decoupled payment adapter in NestJS with custom Axios interceptors and automated retry backoffs, reducing webhook checkout failures to under 0.5%. I also designed a multi-tier MySQL schema for subscription coupons that lowered query latency by 35% under concurrent loads.
On MindFlow, I built an AI extraction pipeline using Google Gemini and LangChain to turn technical documents and GitHub codebases into connected knowledge graphs. I added fallback and recovery logic, and an interactive canvas that lays out concept nodes in real time.
For Ticketly, I implemented OAuth sign-in, Stripe payment workflows, and protections against concurrent double-booking. I also built NotesBuddy’s containerized file-management infrastructure and deployed it on a Linux VPS.
