[ 01 ] Story

Engineering as a craft.

From first commit to building systems that scale, the path has been deliberate: ship, measure, sharpen, repeat.

202201 / 04

First commit

Started shipping production web apps with React and Node, learning the craft by deploying real things to real users.

202402 / 04

Going full-stack

Pushed deeper into infrastructure: Postgres, Redis, Docker, and CI/CD pipelines that stay quiet under pressure.

202503 / 04

Performance focus

Specialized in scalable systems: cache strategy, database tuning, and front-end runtime optimization.

202604 / 04

Open to roles

Looking for teams that care about craft, velocity, and meaningful problems worth solving.
