Description

I help companies fix bugs, improve performance, and deliver small features in existing .NET / ASP.NET Core / Angular applications.

Most of my work involves jumping into existing or legacy projects, understanding the codebase quickly, and delivering practical, maintainable solutions without unnecessary overengineering.

Typical tasks I handle:

Bug fixing in .NET / ASP.NET Core APIs
Angular bug fixes and small UI improvements
EF Core performance and query optimization
API integrations (payments, third-party services)
Authentication and authorization issues (JWT, Identity)
Working with background processing and messaging (RabbitMQ)
Stabilizing applications and preparing them for production

I’m available 10–15 hours per week, work in the EU timezone (Prague), and communicate clearly in English.

If you need someone who can step into an existing application and start delivering value quickly, I’m happy to help.
