Hello, I’m Vaclav
A small studio.
A personal commitment.
HLT3 Studio is my one-person design and engineering business in Zurich. I help businesses build a better website and founders turn a focused app idea into something people can use.
I handle the conversations, design, code, testing, and handover. The person you meet at the beginning is the person responsible for the finished work.

15+ years in software
I build things
I have to live with.
My work spans enterprise systems, cloud infrastructure, and mobile products. I started Health3 to make lab results understandable and useful over time, then built Unbuzz, Spoonlet, and Reelry around different everyday problems.
Owning these products means the work continues after launch: fixing confusing screens, handling releases, and maintaining the systems behind them. That experience shapes how I design and build for clients.
HLT3 Studio is the client-services brand of Health3 AG. My own products are shown in the portfolio so you can inspect the work directly.

Direct and practical
We agree what matters, I show you progress, and we make decisions together. You don’t need to translate your idea into a technical specification.
Small on purpose
I take on work I can personally deliver. We agree a realistic start date and clear limits. Larger parallel projects or round-the-clock support need a broader team.
Access from the start
You have access to the repository and service accounts from the start. Custom deliverables become yours after full payment. I use AI tools where useful and remain responsible for the design, decisions, and testing.
Your next chapter
Let's make something
you're proud to share.
A new website, an app idea, or a project that needs a fresh pair of eyes. Tell me where you want to go.
