What I'm looking for

I’m looking to drive growth and impact in a Senior .NET Engineer role—building reliable backend services, optimizing performance, and delivering robust microservices with strong testing practices using AWS/Azure.

I’m a highly skilled .NET developer with over 10 years of experience designing, developing, and optimizing backend services and web applications. I’m proficient in C#, ASP.NET Core, AWS Lambda, and microservices architecture, with a strong focus on performance optimization and robust testing.

I’ve engineered and maintained backend services using ASP.NET 8 and AWS Lambda, orchestrating integrations with SAP CDC (Gigya) while optimizing event-driven architectures with S3, SQS, and SNS. I build comprehensive unit and integration tests to boost release confidence and create detailed technical documentation.

Earlier, I transitioned a legacy ERP system to a cutting-edge web-based ASP.NET Core application and improved system performance with SEO-friendly upgrades. I also designed payment kiosk services with ASP.NET MVC and Lucene.NET, streamlining search and log investigation through custom indexing and tooling.
