PART-TIME / CONTRACT ONLY – about 15–20 hours per week, evenings CET (overlaps with US East Coast mornings).

Senior .NET engineer with 15 years in banking software. I take over large, partly undocumented .NET systems and keep them running and moving forward: bug fixing, new features, API integrations, .NET Framework to modern .NET upgrades, and SQL Server query and stored-procedure performance. Also led bank-merger and data-migration projects end to end.

Good fit if you have an existing .NET application or database that needs an experienced pair of hands a few hours a week.

Please get in touch only with a concrete role or project. I'm not interested in talent pools, candidate lists or paid career / job-search services.

Senior .NET developer with 15 years in banking software. I've built applications from scratch and maintained large legacy systems: core banking integrations, data migrations between systems (complex T-SQL, performance tuning), bank merger projects. Comfortable taking over undocumented codebases and shipping fixes fast.

Looking for a part-time contract (~15-20 h/week), evenings CET - overlaps with US mornings.
