Freelance · Embarcadero MVP · Delphi → Web
Your Delphi expert — desktop to web.
I'm Dr. Holger Flick. With a Master's in Computer Science and a PhD in Mechanical Engineering, I bring a deep, well-founded engineering education to every project — the kind of rigor that holds up under real load. On top of that: 30+ years in Delphi and a long-standing Embarcadero MVP. Whether you're untangling a stubborn Delphi codebase or ready to bring it to the modern web with Next.js, React, and TypeScript, I'll help you ship it.
