I sit at the intersection of business, product, and engineering — and I build things. If you need someone who thinks beyond typical patterns to ship your AI product, let's talk.

About me

I've been building for 20+ years. Not just code — products, teams, and businesses.

I started building websites in 2002. Since then I've been a frontend engineer, a product manager, a team lead, a startup co-founder, and an indie maker — sometimes all at once. Right now I focus on Generative AI at Tooploox, where I build AI-powered products and help businesses figure out how to actually use this stuff.

I've shipped Minibooks, Avai, Notka, Interior24 and other products from zero. I don't think in frameworks or buzzwords — I think in "what's the fastest way to get this into people's hands?" That usually means ignoring the typical playbook and finding a smarter path.

What sets me apart

Why work with me?

Builder who thinks in business

I've been on both sides — shipping code and deciding what to build next. I understand unit economics, user psychology, and React hooks. That means no gap between your goals and what gets built.

Unconventional problem-solver

I don't follow playbooks. 20 years of building across different industries taught me to spot shortcuts others miss — and to question assumptions everyone else takes for granted.

From enterprise to one-person startup

I've led teams at Opera and Tooploox, and I've built solo products on weekends. I know when you need process and when you need speed. I'll match your context, not force a method.

How I can help

Whether you need a sounding board or a shipped product.

Building

I design and build AI-powered products end-to-end. You tell me the problem, I'll figure out the fastest way to solve it — and deliver something real, not a pitch deck.
