me.

A developer, occasionally a human being.

[ summary ]

Hey — I'm Antoni Saputra, though most people know me as Lixu :). By day I work as a front-end engineer; outside of that I build things for fun and try to document the journey here.

Most of my time goes into the React ecosystem — shipping product, integrating APIs, and keeping the front end from falling apart.

I'm drawn to software that's built with genuine care for the people who use it.

“Programs must be written for people to read, and only incidentally for machines to execute.”

  • [o] Working as a Front-End Engineer at Logika Data — building UIs, integrating the APIs, and tuning SEO and performance.
  • [o] Getting sharper at web and API development — reading more, thinking more, shipping more.
  • [o] Slowly working through new programming languages and competitive programming — minimal crying, decent progress.
  • [o] Writing it all down as I go.
