What I'm looking for

I’m looking for a Mid-Senior .NET backend role where I can take greater ownership, ship end-to-end features in Agile teams, and keep building high-impact microservices with strong debugging and performance work.

I’ve spent the last 4.5+ years building backend features in .NET, with a big focus on ASP.NET Core microservices.

At ExamRoom.AI in Bengaluru, I extended and maintained BFF-pattern services like ClientBFF, ExamBFF, ProctorBFF, and OnboardingBFF for an AWS-hosted AI proctoring platform processing 450–800+ live exams per day.

I designed and optimized REST APIs using CQRS and repository patterns, improved performance with EF Core for domain operations and Dapper for high-throughput reads, and used async patterns like Task.WhenAll and IHttpClientFactory to reduce latency.

I also debugged complex distributed issues, including auth/CORS failures across Cognito JWT flows, and supported releases through GitLab-based workflows and xUnit testing in Agile/Scrum teams.
