What I'm looking for

I’m looking for an Agile/Scrum environment where I can design and optimize .NET Core REST APIs, partner with frontend and API consumers, and deliver secure, scalable backend systems using Azure CI/CD, clean architecture, and strong code quality.

I’m a Senior .NET Developer with 9+ years of experience building .NET Core and .NET Framework applications using C#, SQL Server, and Web API. I design, build, and maintain efficient, reusable, and reliable code across backend and API layers.

I’m especially strong in Entity Framework Core, SQL query optimization, conceptual data modeling, and scalable application design. I shape API contracts with consumers—translating business requirements into high-quality, testable software features—while ensuring clear specifications and reliable integrations.

I’ve delivered measurable impact through SQL and performance improvements (including reducing API response times by 30% and production incidents by 25%), and I implement Azure CI/CD pipelines to improve deployment consistency and reduce release failures by 35%. I thrive in Agile/Scrum teams, mentor engineers, and lead code reviews to keep systems secure, performant, and maintainable.
