I assist you from idea to launch.
Discovery & Planning
We discuss your project and examine how exactly I can support you. If everything fits, we create a detailed roadmap for your project. We define and prioritize the most important features before we start development.
Development & Testing
During the development phase, I implement the discussed features according to priority. I focus on clean code, regular updates, and thorough testing to ensure quality. You will receive regular updates and feedback rounds to make sure we are on the right track.
Launch & Support
When you are ready to release your product, I take care of deployment and long-term operation. Depending on your needs, we develop additional features and continuously improve the product.
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 Erfahrung, Flexibilität und klaren Kommunikation hat er maßgeblich dazu beigetragen, dass wir schnell vom Konzept zur funktionierenden Lösung kamen. Besonders wertvoll war seine Fähigkeit, schnell auf neue Anforderungen zu reagieren und dennoch strukturiert und nachhaltig zu arbeiten.
