Three months of onboarding for a new hire already costs you a quarter of roadmap.

I embed in small dev teams and start shipping roadmap work by week two. You won't have to walk me through the architecture three times, and after the project, your product keeps running.

How I help

I'm Nils – Senior Fullstack Developer specialising in modern web applications. Over the past years I've guided several SaaS products from the first line of code to launch and know what it means to deliver production-ready work under pressure.

With me you get:

  • Fast onboarding: I'm onboarded and productive within days – not weeks.
  • Clean handover: Every feature is documented, tested, and seamlessly integrated into your codebase.
  • Product thinking included: I question before I build – and deliver what's actually needed.

From initial planning to handover to your team

03 phases

  1. 01— Discovery

    Discovery

    Together we look at where your team stands today – which features are waiting, what takes too long, and where bottlenecks occur. We then plan my role within the team and decide together how I can best help.

    Development

    During development I work closely with you and the team. Regular exchange and code reviews are a natural part of my process.

  3. 03— Launch

    Launch & Handover

    After launch I stay as long as everything is running stably. I document everything so you don't remain permanently dependent on me. When new requirements arise later, I'm there.

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.

Jurij Peters

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.
