Hoan Luu

I build backend systems that stay reliable under load.

Node.js / TypeScript engineer in Hanoi — Web3 trading platforms, blockchain products, and production backends at scale.

Senior Backend Engineer · Web3

Hanoi, Vietnam

I lead backend architecture for high-performance services: clear boundaries, observable systems, and decisions that hold up when traffic and teams grow.

Recent work centers on Web3 trading and blockchain products — TRON energy markets, TON trading, metaverse backends. I also run a small AI lab (blog + tooling) as craft proof, not the headline.

How I shape a backend

Traffic → load balancer → edge → runtime → messaging → data. Ops + AI wrap the whole path. Tap or click a block — see what I can contribute on that slice.
