I build engineering organizations, scalable SaaS platforms and high-performing software teams.

For more than 16 years, I have helped companies build, modernize and scale software platforms — from startups to enterprise organizations. My experience spans GRC, FinTech, Mobility, Healthcare, E-Commerce and EdTech, where I have led engineering teams, designed cloud-native architectures and delivered enterprise software.

Unlike many engineering leaders, I remain deeply hands-on. I enjoy solving complex technical challenges, writing production code, reviewing architecture and helping teams deliver high-quality software faster through modern engineering practices and AI-assisted development.

Throughout my career, I have been trusted to join organizations during periods of growth and transformation — building engineering teams, modernizing technology stacks, scaling cloud platforms and aligning technology with business strategy.

I enjoy mentoring engineers, building high-performing teams and creating engineering cultures where people can do their best work. My passion is solving complex technical and business challenges while turning technology into measurable business value.

Featured Project

Building Viamor, hands-on

Not just leading engineering — co-founding and building a product I co-own. Proof that I still ship, architect and scale in production.

Hands-on CTO & Co-Founder · Viamor GmbH

Viamor

A subscription dating & community platform · web, iOS & Android

A modern, real-time dating and community platform serving members across Germany, Austria and Switzerland — with matching, live chat, social feeds, groups and events, and a freemium subscription model.

I co-founded Viamor through my own company, C85 GmbH, and drive it technically end-to-end — from platform architecture and the Elasticsearch matching engine to the real-time messaging layer, the Flutter apps and the multi-provider billing system. A product I own, and still write production code for.
