I ship full-stack and AI products teams can rely on.

Eight years shipping products professionally, from backend architecture to polished frontends that hold up in production. Now I build AI into them too, from multi-agent assistants to models that run on the device.

From forum themes to AI agents.

I started building for the web in 2012, long before "full-stack" was in my vocabulary.

That early curiosity turned into a career spanning advertising agencies, startups, and independent client work.

Today I build with AI in the loop. I plan the architecture, write the specs, and design the screens, then direct coding agents through the build and review every change before it ships. The code is still mine to own, and I care most about the details users never see: clean architecture, fast load times, code that's easy to hand off.

// this is the tip of the iceberg: most of my work lives behind client NDAs I take seriously

01AI · Python · React Native

LUMI

A personal AI assistant built as a multi-agent system, with specialized sub-agents handling daily briefings and background tasks on a schedule, and personalized with my own knowledge vault. A JARVIS-style Android app lets me talk to her by voice with a wake word, control my smart home, and follow finance feeds, so she stays connected to my work, routines, and goals.

02Next.js

Nezopo

An all-in-one store app for small businesses that runs checkout, inventory, customer credit, and sales reports from the phone, tablet, or laptop they already have. It covers camera or scanner checkout with cash, e-wallet, QR, and split payments, low-stock and expiry alerts, stock transfers between branches, staff PINs and roles, loyalty points, and shift cash counts.

AniTrack

An offline-first farm and cooperative tracker for rice and corn growers. Farmers log plots, plantings, and harvests without signal and photograph pests to get an on-phone identification from a model I trained, which a technician then confirms. Cooperatives see harvest forecasts weeks ahead, while municipal agriculture offices see area totals only.

HustoAI

An offline-first personal finance app with an encrypted on-device database and a local AI assistant that surfaces spending insights without an internet connection. Money is stored as exact integer amounts with balanced ledger writes, and optional cloud sync resolves conflicts explicitly instead of letting the last write win.
