Sound Familiar?

Unreliable freelancers who disappear mid-project?
Code that breaks every time you add new features?
Technical decisions that slow down your team?
Turning your AI idea into a working product?

I've spent 10+ years solving exactly these problems.

Full Product Development

You have a product idea but lack the technical team to build it.

I take products from concept to launch, handling architecture, development, and deployment. You get a production-ready application without managing multiple contractors.

AI/ML Integration

Robin's expertise and implementation suggestions were invaluable while building our project. Correlation between focus on user experience and actual performance of the app is still rare these days, however Robin did excellent job in both areas.

About Robin

I'm a software developer based in the Czech Republic with over 10 years of experience building web applications for companies across Europe and the UK.

I've worked with startups shipping their first MVP, helped established companies modernize legacy systems, and led technical decisions for growing engineering teams. My approach: clear communication, quality code, and treating your project like my own.

I've been working remotely since 2014, long before it became the norm. This means effective async communication, proactive updates, and timezone-flexible scheduling are second nature to me.
