About

Trần Đình UY

Software engineer

Việt NamEst. 2024

I'm a software architect focused on high-performance systems, automation, and the digital experiences in between.

Whether debugging a JVM issue, refining automation pipelines, or training for a marathon, I believe in shared knowledge and well-documented systems.

Manifesto

Most engineering writing online is either sales copy or a tutorial. I want this to be the third thing — careful, opinionated, and useful five years from now.

Currently

Writing engineering essays, building Manul X, and exploring system-design problems in public.

What you'll find here

Long-form essays on systems and tooling. Postmortems with the timeline still intact. Notes on the boring parts of shipping software — migrations, observability, dependency budgets. Occasional Vietnamese and Japanese translations of pieces I think more people should read.

What you won't find here

Listicles. Tool-of-the-week posts. AI-generated rewrites of someone else's article. Anything I haven't tested or wouldn't recommend to a friend on call at 3am.

Influences

Writers and books that shaped how I think.

  • Dan Luuwriting on hiring, latency, and what actually breaks in prod
  • Julia Evansfor proving that approachable can mean rigorous
  • Simon Willisonfor showing what it looks like to think in public
  • Hillel Waynefor taking formal methods seriously without being precious
  • Designing Data-Intensive ApplicationsMartin Kleppmann's quietly definitive book
