AI-first

How I can help

I build products from the first idea to the first customers — or advise you while you build it yourself.

Web apps & SaaS
Got a product idea? I'll turn it into an app that's ready to sell — with user accounts and online payments built in.
AI features & agents
Let AI handle the repetitive work. I build assistants and agents that save your team and your customers time.
Websites & landing pages
A fast site built for Google that leads visitors straight to getting in touch — like this one.
Consulting & architecture
Make sure you're building it right before you spend the budget. I'll help you choose the architecture, the stack and the rollout plan — including how to bring AI into your team's work — as a one-off consultation or ongoing advice.
