A Bit About Me

The Journey So Far

I started coding back in 2004 with simple HTML sites, and somehow ended up building systems that handle millions of users. Along the way, I've discovered that the best software isn't just about clever code - it's about solving real problems for real people, especially for founders who need their vision turned into working software. Clients hire me because I'm reliable, I work with integrity, and I move fast when deadlines are tight.

These days, I work with TypeScript, React, Node.js, PostgreSQL, Docker, and AI coding tools like Claude and Cursor. This AI-augmented workflow lets me ship faster while maintaining the quality and stability that comes from 14+ years of experience knowing what works.

From my own projects like MoaiTime (a productivity platform) and WeWentCarRacing (because I love motorsports), to client work with companies like Philips, RWE, and Innogy, and smart-city projects for the government - I enjoy building things!

What Drives Me

✓ Building things people love - There's nothing quite like seeing someone actually use and enjoy something you've built. That's what keeps me coding.
✓ Learning constantly - The tech world moves fast, and I love keeping up. Whether it's a new framework or an old problem with a fresh approach.
✓ Sharing knowledge - I write about my projects, contribute to open source, and enjoy helping other developers when I can.
✓ Fast, but not rushed - I move quickly without cutting corners or stability issues, so you get dependable delivery without last-minute surprises.
✓ Making things simple - The best software is invisible to the user. Complex problems shouldn't require complex interfaces.
✓ Integrity in communication - I say what I know, what I don't, and what I'm doing next so you always have the full picture.

🇩🇪 Übrigens, ja, ich spreche natürlich auch Deutsch! Früher hatte ich eine deutsche Version dieser Webseite, aber oftmals habe ich die Texte vergessen zu übersetzen, deshalb halte ich es jetzt nur auf Englisch!

Client Work

Over the years, I've worked with companies ranging from early-stage startups to global enterprises. Here are some areas where I've made a meaningful, reliable impact:

Built for Startups & Founders

I work as your technical co-founder without the equity. Business requirements come first - I translate your vision into working software with clear timelines, honest tradeoffs, and dependable delivery so you can focus on growth.

✓ MVP to production in weeks, not months

✓ Solo full-stack (no team overhead)

✓ Business-first decisions

✓ Built for scale from day one

Scaling Platforms

I helped scale an EdTech platform from thousands to millions of users across the UK education system. This involved optimizing database performance, implementing caching strategies, and building resilient architecture that could handle rapid growth.

Technical Leadership

I've led development teams and guided technical decisions that improved product quality and accelerated delivery timelines without sacrificing stability. Part of this includes mentoring developers and establishing engineering practices that scale with the team.

System Modernization

I've successfully managed cloud migrations, containerization projects, and infrastructure modernization efforts. These projects typically involve migrating terabytes of data and legacy systems while maintaining service availability and data integrity.

My Personal Work

Here are some highlights from my work - personal projects, open source contributions, and experiments that showcase different aspects of my development skills and community involvement.

Deep Gamer

An experimental machine learning project that creates an AI capable of learning game controls through screen capture and neural network training. Built with TensorFlow and Python, it uses Inception V3 architecture to process 640x360 gameplay footage and generates control outputs for autonomous gaming. Features a specialized "WASD Network" optimized for driving games and supports 9 different control actions.
