Senior engineering that fits you —
personal, focused, complete.
As a freelance senior full-stack developer, I support companies, founders and development teams where it matters most: as the developer for your project, as reinforcement for your team or as a technical sparring partner. You work directly with me – from the first idea to software running in production.
- Remote-first across Europe & internationally
- German & English
- On-site in Fulda by arrangement
- Limited capacity for selected projects
How I can support you
Every project is different. That’s why there is no standard package, but the model that fits your goal, your team and your timeline.
Project development
I take ownership of delivering your project – from websites and web apps to custom software. With clear milestones, early releases and a complete hand-over.
- Websites, web apps & portals
- APIs, integrations & microservices
- You own the source code & documentation
Team augmentation
Your team needs senior experience for a while? I get up to speed with existing codebases quickly and bring architecture, code quality and pace to your project.
- Working within your processes & tools
- Code reviews & architecture decisions
- Knowledge transfer instead of dependency
Interim CTO & founder advisory
For non-technical founders and young companies: sound technical decisions from the start – and the certainty that the source code stays in your hands.
- MVP scoping & prioritization
- Make-or-buy & tech stack selection
- The source code stays in your hands
Team enablement & process setup
Clean branching strategies, CI/CD pipelines, agile rituals and technical interviews for new hires – so your team delivers fast and safely, even without me.
- CI/CD & branching strategies
- Agile processes & code review culture
- Technical interviews
Freelancing alongside a permanent senior role
I’m also employed as a senior developer in industry. For you, that means current practice from large systems, independence from your project and a deliberately small number of clients.
Current industry practice
Microservices, cloud and quality processes from daily use – not textbook theory.
Few clients, full attention
I only take on as many projects as I can handle with full care. We discuss capacity and start date openly in the intro call.
Reliable planning
Fixed time slots, clear milestones and transparent communication instead of surprises on delivery day.
Direct line
You always talk to me. I answer questions personally, and we make decisions together.
From your inquiry to production
Five clear steps – so you always know where your project stands.
Intro call
We talk about your goal, your users and the scope – without obligation and in person.
Scoping & quote
I define the scope, prioritize the MVP and prepare an individual quote with clear milestones.
Iterative delivery
Early, working increments and regular check-ins: you see progress instead of waiting for it.
Go-live
Delivered complete: authentication, error handling, tests, documentation and hand-over of the source code.
Operation & support
If you like, I stay on board: monitoring, updates and further development through support packages.

Questions about freelancing
The essentials of working together – and if your question is missing, just write to me.
How much capacity do you have for my project?
I freelance alongside my permanent role and deliberately take on only a few projects at a time. How much time your project needs and when we can start is something we discuss openly in the intro call. I only make commitments I can keep.
Do you work remotely or on-site?
Remote-first for clients in Germany, Austria, Switzerland and internationally, in German and English. On-site meetings in and around Fulda are possible by arrangement.
Who owns the source code?
You do. Source code, documentation and access credentials are handed over completely, so you never depend on me.
How is the work billed?
Every project is calculated individually. After the intro call, you receive a transparent quote with clear milestones. For ongoing collaboration, such as team augmentation, we agree on a suitable model.
Do you also provide support after go-live?
Yes. Through support packages I take care of monitoring, security and dependency updates, functional testing and further development – with defined response times, guaranteed in the Premium package.
