Client Projects: From Idea to Working Software

A portfolio of digital products, web apps, and UX redesigns built by David Rozsa, from enterprise workflow digitalization to health-tech MVPs and EdTech platforms. Each project went from initial brief to shipped software.

What kind of projects do I take on?

I work with founders and product teams who need a complete digital product built: not just mockups or a prototype, but working software they can ship. Each project on this page went through the same process: understanding the actual problem, making architecture decisions, designing the UX, and delivering a production-ready result. My clients range from enterprise teams digitalizing internal workflows (Magyar Telekom, GLS) to solo founders building their first health-tech or EdTech product from scratch. What they had in common: they needed someone who could own the full product journey from vision to launch, without assembling a large agency team. If that sounds like your situation, the contact link is at the bottom of this page.
