About me
Senior C# / .NET Backend Developer with 16+ years of experience architecting and delivering high-load enterprise portals, financial systems, and robust integration services.
My core technical stack includes .NET Core/.NET 6/7/8, C#, ASP.NET Core Web API, MS SQL Server, PostgreSQL, Entity Framework Core, and RabbitMQ. I specialize in designing scalable backend architectures (SLA 99.9%), writing high-performance asynchronous services, optimizing complex database queries, and implementing secure authentication pipelines (OAuth2/JWT).
Beyond enterprise development, I build and maintain open-source solutions (such as custom auth systems and task-tracking tools). I follow Clean Architecture, SOLID principles, and clean code practices. Currently open to remote contract opportunities and direct project collaborations requiring solid backend engineering and secure API integrations.
