Freelance .NET Tech Lead, fully remote
Nicolas Cousin joins your team as a freelance .NET Tech Lead, for long assignments, fully remote, in France and internationally. He has over 10 years of experience, including critical banking applications of around 500,000 lines of code.
When to call me
- Your .NET application is hard to evolve and every release is scary.
- You need to modernize without a full rewrite, or migrate to .NET 10.
- The team lacks a technical lead: architecture choices, code reviews, testing practices.
- Your releases are manual and risky.
What I bring
- Progressive modernization: splitting the work into batches, reducing technical debt, a testable architecture.
- Reliable releases: CI/CD pipelines, automated tests, quality checks.
- Team leadership: code reviews, technical decisions, helping developers grow.
How we work together
- Long contract / time-and-materials missions, preferably fully remote. Occasional travel possible from Lille.
- In French or in English.
- Direct contract, through an umbrella company or through your procurement / vendor platform.
- Availability: let's talk about it during a 15-minute call.
Not sure what you need?
Start with a Flash audit: in 2 days, you know where your code stands and where to start. If you then entrust me with the remediation, I already know your application.
