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 that eats hours every day and is error-prone.
After
A lean AI agent or 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.
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.
Websites and landing pages too, when they’re part of a tool or product we’re building. Coded, not drag-and-drop.
