Building software
since 2005.
I'm Royendgel Silberie — a fullstack developer and founder based in Hoensbroek, Netherlands. For over 20 years I've built software for governments, enterprises, and startups across 3 continents.
I don't just write code — I architect, deliver, and operate software. I run three live SaaS products myself, which means I know what it costs when architecture decisions go wrong at 2am. That perspective shapes every decision I make on your project.
Principles that don't bend under deadline pressure.
Code you can be proud of
Clean, documented, tested. Not rushed to hit a deadline, not a mess to maintain. Every codebase I deliver is one I'd sign my name to.
Business first, tech second
Technology is a means, not an end. I spend time understanding your business before writing a line, so every decision serves a real purpose.
Transparent by default
Regular demos, honest progress updates, no black boxes. If something is harder than expected, you hear it from me immediately — not weeks later.
In it for the long run
Many of my clients have worked with me across multiple projects over several years. That's not an accident — it's the relationship I aim for.
Technologies I know deeply, without stack dogma.
Python, Django, and FastAPI are strong foundations, but I work wider: Rust for performance, React or Vue for interfaces, and the cloud/data stack that fits your system. Not a list of buzzwords — tools I've used at production scale.
