I build full-stack apps end to end.
Next.js and React Native on the front, Express and MySQL behind it. I care about software that stays out of the way.
Selected work
All projects →CircleNet
2024A social platform with feeds, groups, anonymous messages and live streaming, built three separate times against the same Express and MySQL backend.
FixLog
2026A repair log for the phones I fix. Devices, faults, parts and turnaround. I use it daily.
MusicPlayer
2026A local-first music player for Android. Reads what's already on your device. No account, no streaming, no network.
Writing
All posts →React Native tells you something's wrong. It rarely tells you what.
22 September 2026Five bugs from one migration session. Every error was accurate. None of them pointed at the actual problem.
The right answer, the wrong shape
19 September 2026Five bugs from one day. Every one passed a value that was correct in one layer and unusable in the next. Nothing crashed, every endpoint returned 200, and every fix was a coercion.
There's no sender to hide
15 September 2026Whispers is CircleNet's anonymous message feature. The interesting thing isn't that it hides who sent a message. It's that there's nothing to hide in the first place.
I'm open to freelance work and full-time roles. The fastest way to reach me is email.
