What I'm looking for

I’m looking for a role where I can combine full-stack development with strong QA, collaborating with teams to deliver efficient, secure, production-ready software in a fast-paced environment.

I’m a Senior Application Developer and software engineer with 2 years of experience spanning Full Stack Development and Quality Assurance at Sierra ODC Private Limited in Coimbatore. I build reliable, scalable applications using .NET and C#, with strong focus on REST API integration, MVC/MVVM architecture, and CRUD database operations across SQL databases like MySQL and SQLite.

I also own quality end-to-end—API testing, bug tracking, debugging, troubleshooting, and performance optimization—so releases are efficient, secure, and production-ready. I’m known for algorithm design, system architecture, and code optimization, and I enjoy collaborating cross-functionally while staying productive and adaptable in fast-paced settings.
