Your technical partner for AI — a builder, not just a consultant.
I build AI agents, tools and automations that take real work off your plate — from first prototype to running in production. No agency overhead, no timesheets.
Is this for you?
Solo & Consultants
Solo founder, coach or consultant? You've got an idea or an annoying manual process — but no desire to deal with the tech. I become your on-call technical co-founder.
Teams & Startups
Small team or startup? You may have your own engineers, but not enough hands for AI work. I plug in where it matters — as extra capacity for AI features, automations and agents.

How I work
Before
An Excel mess eating hours every day.
After
A lean web app with automations and clean UI.
That's how I work — I don't talk about AI, I build with it.
Services
AI agents, tools, automations and web apps
AI agents, tools, automations and web apps that run in production — not strategy decks alone.
Autonomous AI agents
Agents that act on your behalf — research, triage, respond, or orchestrate tasks. Built on modern agent frameworks like OpenClaw and Hermes.
AI tools that do real work
Custom tools that solve concrete business problems — calculators, dashboards, internal apps, and AI-powered workflows that save hours every week.
Automations that handle recurring work
End-to-end process automation: data sync, notifications, integrations between your tools, and workflows that run without you.
SaaS & web apps
From MVP to production-ready product — prototypes, SaaS platforms, and full-stack web apps with a modern TypeScript stack.
And yes — I build websites and landing pages too. But as the technical foundation for your tools and products, not as a WordPress page-builder.

Pay for outcomes, not hours.
Pause anytime — your banked days never expire.
