About me

I am Kavinda Rathnayake, a software engineer who enjoys building reliable products across the stack.

I bring three years of experience, with most of my time spent on backend engineering while still staying very comfortable on the frontend.

I am a big fan of open source, and I enjoy building my own tools. TypeScript, Rust, and Java are the primary languages I keep returning to.

Most of the products I build are web applications, especially backend systems and REST APIs shaped around different architectures such as microservices and monoliths.

On the frontend, I usually work with React, Vite, TanStack Start, and Next.js depending on the requirement, with Tailwind CSS and shadcn/ui helping me move fast without losing design quality.

Working style

Backend-first, product-minded, and always curious.

About me in code

A TypeScript flavored version of how I think, build, and ship.

This section turns the same profile into code: a small, expressive module that reflects my engineering focus, tools, and working style.
