Hi, I'm Jonatana 👋

Fullstack developer. I turn workflows that waste your time into systems that just run: web apps, Android apps, and the servers they run on.

Writing code since I was 12, and available for freelance work, remote or local.

What I've been building

• Brother: an AI research assistant for Bible study. It answers from a large library of publications, and every quotation is checked against its source.
• Wifi Efitrano: community Wi-Fi where every person has their own login, with FreeRADIUS in my homelab and a native Android admin app.
• LibraryLite: an offline-first mobile reader that keeps its catalogue current by detecting upstream changes.
• Karaoke Broadcasting: a desktop app that turns songs into karaoke videos, with local vocal removal and a per-syllable timing editor.
• Nofy: pay-as-you-go AI images, video, and music from a mobile money wallet.

Most of these live in private repositories. More on unviray.com, and I'm happy to walk through the code on request.

Open source

• pyplater: build HTML components with Python
• pyfield: field collections for your forms

How I work

1. Style and readability first, then scalability.
2. Spot how a workflow can be simplified, then automate it.
3. Every tool has to pass one test: is it sweet to use?
