What I'm looking for

I seek a mid-level software engineering role focused on full-stack or cloud-native development, collaborative agile teams, DevOps-driven workflows, and opportunities to design scalable systems and grow into architecture or SRE responsibilities.

I am a dedicated software engineer with 3+ years of hands-on experience building scalable web and serverless applications using React, Node.js, ASP.NET Core, and AWS. I have a strong foundation in computer science from the University of Moratuwa and a proven track record delivering production applications, design systems, and automated invoicing solutions.

I thrive in agile teams, implement DevOps and CI/CD practices, and build reusable components and packages. My notable achievements include creating a design system with Storybook, upgrading React Native applications, and designing a microservices-based enterprise simulation using modern .NET and cloud technologies.
