I'm a fullstack engineer in Ho Chi Minh City, Vietnam. I like problems that touch the whole stack — from RTMP packets to React components to AWS bills. I write TypeScript and Go for production, Java when the job calls for it, and dabble with whatever else looks interesting.

Right now I'm at FAVOLIST5 ASIA, shipping a social content-sharing platform built as ~11 TypeScript microservices on AWS ECS Fargate. On the side I'm building letslive.work, a Twitch-like livestreaming platform — RTMP ingest, multi-bitrate HLS, Go microservices, the whole pipeline.

Before that I interned at HPT Vietnam, where I built an internal chat and video-call app over WebRTC and WebSocket. I just finished my Bachelor of Software Engineering at the University of Information Technology (VNUHCM).

I write occasionally at sen1or.blog. I read more than I write. Currently most interested in: media pipelines, distributed-systems observability, and making AWS bills smaller.
