I build web apps end to end for small companies that have outgrown spreadsheets. Next.js and TypeScript on the front, Node or Hono on the back, Postgres or Supabase underneath, deployed somewhere you own.

Recent work: an ERP for a creative school covering enrolments, classes, staff, billing and reports. A marketplace builder for Indonesian small businesses with payments, shipping and Meta tracking wired in. An AI chiptuning configurator for a German tuning company. A mobile Bible app. A handful of marketing sites built on a CMS the client edits themselves.

I work solo, so you talk to the person writing the code. I quote a range first, then a real number once I have seen the data, and I put scope in writing so the price holds. Based in Indonesia, GMT+7, one hour behind Perth.
