Software Engineer & CTO

Converting caffeine into code in real-time

CTO and passionate software engineer who loves building things that scale and make a real impact. I built Europe's largest influencer affiliate platform (Filify) from zero to millions in revenue, while also engineering resilient infrastructure handling €1M+ in annual payments. I thrive in fast-moving environments where ownership, responsibility, and teamwork drive results.

About Me

Zero to One Builder

Built Europe's largest influencer affiliate platform from scratch, scaling to $2.5M+ revenue and handling €1M+ in automated payments.

Full-Stack Engineer

Fluent in 15+ programming languages. From low-level Rust systems to high-performance TypeScript web apps, I build end-to-end.

Competitive Programmer

Advanced to NWERC 2023 in ICPC. Master's thesis on implementing groundbreaking maximum flow algorithms. Love algorithmic challenges.

Team Player

Thrive in fast-moving startup environments. I take ownership, ship fast, and believe great products come from great collaboration.

When I'm not coding, you'll find me at Copenhell (Denmark's biggest metal festival), hitting the gym for strength training, exploring Copenhagen by bike, or perfecting my coffee brewing technique. I also speak Danish Sign Language and love connecting with diverse communities.

I'm always excited to work on challenging problems with awesome people. Whether it's scaling infrastructure, optimizing algorithms, or building something completely new - I'm down to build cool shit together.
