What I'm looking for

I’m looking for a role where I can lead architecture and modernization—designing microservices, secure REST APIs, and cloud-native systems on AWS/Azure—while collaborating with product and engineering teams to improve performance, maintainability, and delivery speed.

I’m a results-driven Senior .NET Solution Architect with 9+ years of experience architecting, designing, and delivering scalable enterprise applications. I build secure, high-performance RESTful APIs and lead modernization from monolithic systems to microservices-based architectures.

I’ve consistently driven measurable improvements—like reducing API response times by approximately 35% and enabling bulk processing of 10,000+ records per operation (reducing manual effort by over 70%). I’m experienced with OAuth2/JWT authentication, advanced SQL optimization, and production support with troubleshooting and RCA.

My work spans cloud-native solutions on Microsoft Azure and AWS, including services such as Azure App Services, AWS S3, CloudWatch, SQS, and RDS. I also bring strong DevOps practices with Docker, CI/CD pipelines, release management, and collaboration using Git, Bitbucket, and TFS.

I enjoy leading cross-functional teams and translating requirements into reliable systems, supported by technical documentation, code reviews, and unit testing. I also leverage AI-assisted development tools such as GitHub Copilot and ChatGPT to accelerate delivery and improve code quality.
