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 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 — 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.

Benefits

Everything you need from a technical partner for AI agents, tools and automations — so you can focus on your business while I build and ship.

Task board

Kanban board — you always know what's in progress.

Production-grade code

TypeScript, tested and deployable — not throwaway prototypes.

Async-first

No standing meetings. Chat and email, on your schedule.

Fixed price

Same rate every week or month — no surprise invoices.

Flexible plans

Pause anytime. Paid days never expire.

Build + run

I deploy, host, and maintain what I build.

Modern stack

TypeScript, React, NestJS, Astro — production stack, not no-code duct tape.

Integrations

CMS, payments, email, analytics — wired into your stack.

Technical SEO

Search-ready when your product needs to be found.

Pricing

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

Here's how it works: you buy a bank of days for me to work on your projects. Don't need anything right now? Pause — by the day, with one click. Days you've paid for but haven't used don't expire. They stay in your bank, and you draw on them whenever you need them.

  • Maximum flexibility — pause by the day, anytime
  • Zero waste — paid days never expire
  • No lock-in — no binding contract, no notice period
  • Predictable cost — fixed price, no timesheets
  • A real partner — I know your project, no re-onboarding
  • Ready instantly — no recruiting, no agency overhead
