About

Sune Kara

I'm originally from Port Harcourt, Nigeria. I owe most of what I know to open source.

I started the way most people do by picking up tools, following up tutorials, shipping things that looked finished but did not hold up under real conditions.

At some point I stopped trying to learn more things and started trying to understand fewer things better and that shift changed everything about how I build.

I use expo, neon, polar.sh, upstash, and many other known tools regularly enough that I can tell you exactly where each one gets annoying.
