I work remotely with clients across Germany, and on-site across the Ruhr Area and Rhineland. If your office is in Essen, Dortmund, Düsseldorf, or Cologne, I'm under an hour away by train.
I work out of Bochum for teams across North Rhine-Westphalia. The short hop to Essen, Dortmund, Düsseldorf, and Cologne makes same-day on-site work possible without losing a travel day. If you need a workshop, pair-coding session, or architecture review on short notice, that usually fits.
In Bochum itself, I regularly work with SaaS startups near Ruhr University and with mid-sized software teams modernising existing products. If your backend is solid and the frontend or AI side needs to move faster, the working model usually fits.

I'm Nils – Senior Fullstack Developer based in Bochum, Germany. I help SaaS companies and scale-ups reduce technical debt, bring products to market faster, and build websites that truly perform. I specialise in Next.js, Headless CMS, and Product Engineering.

I'm flexible with technology, but especially enjoy working with:

We discuss your project and figure out exactly how I can support you. If everything fits, we create a detailed roadmap. We define and prioritise the most important features before development begins.
During development I implement the agreed features by priority. I focus on clean code, regular updates, and thorough testing to ensure quality. You receive regular updates and feedback rounds to make sure we stay on track.
When you're ready to go live, I take care of deployment and long-term operation. We continue to develop further features and improve the product as needed.
„There aren’t many true full-stack developers. Fewer still can take on deeply complex problems and genuinely solve them. Nils is both, and more. He brings technical depth, clarity of thought, and a calm, reliable presence to every project. A highly respected and recommended addition to any team. And when he’s not coding, he’s out training for triathlons; a true embodiment of work hard, code hard, play hard. On all fronts, Nils is a machine.“

„At objego, I worked with Nils in different teams and phases of the company - from greenfield features to legacy migrations. What always impressed me was how quickly he could slot into new setups and immediately start contributing real value. He brings a strong mix of technical depth, calm communication, and the flexibility to adapt to changing requirements. You always felt in good hands when Nils was involved.“

„Nils war einer der ersten, die unser Produkt technisch mit aufgebaut hat. Mit seiner strukturierten Arbeitsweise, Flexibilität und klaren Kommunikation hat er maßgeblich dazu beigetragen, dass wir schnell vom Konzept zur funktionierenden Lösung kamen. Besonders wertvoll war seine Fähigkeit, Unklarheiten in Anforderung proaktiv und kreativ zu lösen und ein gutes Auge für UI.“
