A retrospective of quiet, durable machinery: APIs, event streams and real-time services, built in JavaScript and TypeScript and hung for daily use. Please walk slowly — most of the work happens where nobody looks.
Luu Buu Phuong works in the medium of the backend — composing services that answer quickly, fail gracefully and keep running long after the launch party ends.
Over nearly a decade, Phuong has built Node.js systems for fintech, logistics and media companies: payment APIs handling millions of requests a day, real-time dashboards streaming over WebSockets, and event-driven pipelines that keep distributed teams in sync.
The practice favours clarity over cleverness. Typed contracts with TypeScript, honest observability, small composable services and test suites that read like documentation are recurring motifs. Performance work — profiling the event loop, taming memory leaks, shaving p99 latency — is treated as craft rather than firefighting.
Phuong is equally at home pairing with frontend engineers on a GraphQL schema, mentoring juniors through their first production incident, or quietly migrating a monolith one module at a time without anyone noticing the floor move beneath them.
“Good backend work is like good gallery lighting: when it's done right, nobody notices it — they only notice everything else looks better.” — From the artist's statement
