From idea toreal-worlduse.

I build products with immediate wow factor that deliver on their promise in real use.

My father built with concrete in groundworks; I build with code. Most of his work stayed underground, yet entire buildings stood on it. Today he's an inventor. We work with different materials, but the principle is the same: everything depends on what you don't see at first.

I started making things for screens at 14. Photoshop, banners, websites — if it appeared on a screen, I wanted to understand how it was made. I built my first sites with e107 CMS, then moved to WordPress. Wanting more than templates pushed me toward more complex systems.

Then came the questions: why does someone click here and not there? Why does one product work while another doesn't? I started looking beyond the interface and code for answers — in the business model and in how the product reaches people.

I wasn't following a preset plan. Each new problem forced me to learn something new. That's how design, development, business, and marketing ended up side by side.

Today I'm building two products of my own. titkar.ai turns one sentence into an invoice for Hungarian microbusinesses. gondnok.app reviews your online store at dawn and does the work you've entrusted to it.

What interests me is turning new technology into a product people keep using after the impressive demo is over.

How I work

I keep the whole process connected.

01

AI speeds up the work. I own the outcome

I work with AI agents every day, from research through code. I set the goals and constraints, then review the result.

02

Decisions don't get lost in handoffs

I make product, design, and technical decisions in the same context. That makes the consequences of each decision visible across the others.

03

I learn from working versions

I get the smallest working version into users' hands as early as possible. How they actually use it determines what I build next.

This site was built the same way
