Who I am

I'm an independent software developer and entrepreneur solving real-world problems for 10+ years. My expertise spans product design, full-stack development, system architecture, modern web technologies, infrastructure and operations.

I turned a green-field idea into a fully launched product, drafting the business plan, designing the UX, implementing it end-to-end, landing early customers, and running 24 / 7 cloud operations. I've built mission-critical systems in the financial industry from the ground up that dozens of banks depend on every day.

Between projects you’ll find me scratching my own itches - writing small utilities, experimenting with new tech, or tinkering with a half-finished hardware prototype.

Currently based in Switzerland, I’m running duupay and partnering with teams worldwide to turn ideas into reliable, production software. Open to select collaborations.
