About
I’m a Full-Stack Software Engineer from Colombo with 4+ years of experience building and maintaining production applications, especially with C#, .NET (ASP.NET Core), REST APIs, and SQL Server. I enjoy working end-to-end—from designing backend services and optimizing database performance to creating responsive, user-friendly frontend experiences with Angular, React, and TypeScript.
In my work, I focus on clean code, reliable architecture, debugging and root-cause analysis, and delivering improvements through Agile collaboration. I’ve contributed to healthcare and revenue cycle management platforms and I also build customer-facing SaaS-style applications (including booking and facility management) using React and React Native, while supporting CI/CD and cloud-ready workflows with Azure and container tooling.
