Düsseldorf: agencies, SaaS teams, and the finance scene

In Düsseldorf I often work with agencies building content platforms for clients in finance and advertising, and with SaaS teams scaling their products. The focus is usually on speed of delivery and on clean handover when the agency project moves to an internal team.

Train from the Ruhr Area takes about forty minutes. That makes weekly on-site meetings realistic without hotel costs or time lost on travel.

Testimonials

„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.“
