About me
Backend .NET developer with 10 years of experience on real production systems. I build reliable backends and make slow ones fast.
My strongest areas: optimizing slow EF Core and SQL queries, migrating SQL Server databases to PostgreSQL, and building clean REST APIs (Clean Architecture, CQRS, MediatR). Stack: ASP.NET Core, EF Core, SQL Server, PostgreSQL.
I work inside existing codebases without breaking what works, and explain what I did in plain language. Tell me your problem before you order and I'll tell you honestly if I can help.
