Building BarterBai: a barter app for stuff you already own
An iOS app where neighbors swap items instead of buying new. SwiftUI, Convex, and three different AI models doing the boring work.

I'm a developer. I like hard problems, small teams, and shipping things.
13+ years of it — I sit with your team, translate what the customer actually wants, and ship to production. SAP at Accenture, frontend architecture at Fednot, AWV and Digipolis, now AI and Web3 under my own name.

About
Turns scope into something that actually runs
Part consultant, part architect, part solo builder — 13 years of whichever was needed
I've been writing production code since 2011. I started in SAP and Dynamics AX consulting at Accenture, moved into frontend architecture working inside teams at Fednot, AWV, Digipolis and VikingCo, and over the last few years I've been shipping my own AI, Web3 and mobile products on the side. Sometimes I'm the solo engineer. More often I'm sitting with a team, translating what the customer actually wants into something that runs in production. I'm TypeScript-first (Next.js, NestJS, Convex) with working fluency in Python, Swift and Solidity — I follow the problem, not the stack. Newest chapter: building with Claude, OpenAI and Gemini on things like BarterBai, OBOL and Global Pet Sitter. I automate my own work, move fast, and prefer building over meetings.
