What I'm looking for

I seek backend-focused roles building scalable, secure APIs and integrations with collaborative teams, strong testing and CI/CD, and opportunities to improve architecture and performance.

I am a .NET Backend Developer with extensive experience designing and building scalable backend systems, RESTful APIs, and admin platforms using C#, ASP.NET Core/Framework, WCF, and Entity Framework. I emphasize performance tuning, secure authentication, and reliable integrations to meet business needs.

I have delivered production systems for trading and payment platforms — including API backends, admin panels, and multi-gateway payment processing — improving responsiveness, scalability, and data integrity across services. I collaborate closely with frontend teams and apply DevOps practices to streamline deployments and QA.

I hold a Master's in Informatics and have a track record of migrating architectures and improving system reliability through database and tooling choices, automated testing, and security measures such as JWT, SSL, and tokenization.
