Who
About
I'm Dragoș Cătălin. I build products end to end — from cloud and network to the app in your pocket. I started coding at about ten, got paid for it at fifteen and have shipped for a living ever since.
Today I run my own products: codai, an AI gateway with desktop and phone apps; Brivio, invoicing and e-Factura for Romanian businesses; Horae watch faces on Google Play. I work from Romania, remotely, for startups that need an MVP end to end, Romanian companies that need invoicing and automation, and EU teams that need cloud, network and architecture done right. I take on few projects, and I finish them.

How I work
- 01
Verify, don't assume
Nothing is done until the verifying command ran and I saw the output. Preregistered thresholds in research, frozen test vectors in crypto, deflated Sharpe in trading.
- 02
Money must balance
Double-entry ledgers, immutable journal entries and hash-chained audit logs — in an ERP and in a game economy alike.
- 03
Every surface
Web, desktop, mobile, extension, MCP, SDK. A feature isn't finished until every consumer has it.
- 04
Latest stable, always
Next.js 16, React 19, TypeScript 7, Tailwind 4, Rust/Tauri 2. Upgrade early, upgrade in slices.
- 05
Agent-native
Rules, skills, hooks and memory for the AI agents I work with, so they decide with me — not for me.
- 06
Romania first, EU ready
e-Factura, ANAF, SAF-T, RON and BNR rates. Everything bilingual.
