## About

I build systems that scale e-commerce brands.

For the past 2+ years as CTO at Stay Cold Apparel, I’ve been responsible for transforming the tech, data, and growth infrastructure of a fast-scaling DTC brand — moving from 7 to 8 figures, with a clear path toward 9.

The focus was never just tech. It was:

- Conversion rate optimization at scale  
- Data-driven decision making (A/B testing, surveys, behavioral analysis)  
- Custom Shopify Plus architecture  
- Automation across marketing and operations  
- Sales psychology applied to UX and lifecycle  
- Retention and loyalty systems  

Alongside that, I’ve been running Nerds of all Trades GmbH since 2016 — building, scaling, and advising digital businesses.

One of those was Uhrwerk Berlin, a watch brand I founded and scaled to 100,000+ units sold.

Today, we focus on:

- E-commerce consulting for scaling brands  
- Building SaaS products for DTC (currently: audience growth tools)  

Before that, I spent years in senior and principal engineering roles at companies like ImmobilienScout, RTL, and others — building large-scale systems and leading frontend architecture.

### What I bring

- 28+ years in software and internet businesses  
- Deep understanding of both engineering and revenue  
- Proven ability to scale systems and organizations  
- Strong bias toward execution and measurable outcomes  

### What I’m interested in

- Working with brands doing €10M–€100M+ aiming for the next level  
- SaaS collaborations in the e-commerce ecosystem  
- High-impact projects where tech directly drives revenue  

Not actively looking for roles. Open to relevant conversations.
