Hey there!
I'm Amandi Udawatta

I am a Software Engineer based in Kalutara, specializing in full-stack development. I enjoy crafting seamless, intuitive user experiences, sometimes with a little bit of fun built in.

About Me

I'm a Fourth-Year Computer Science Undergraduate with over 1.5 years of industry experience, driven by the challenge of building reliable, scalable systems and seeing them come together end to end. I enjoy working across the stack and have experience delivering full-stack applications, with a strong foundation in backend development.

Most of my hands-on work involves designing APIs and data-driven systems using Spring Boot , FastAPI, and PostgreSQL , while also contributing to frontend features that focus on usability and performance. I value clean, maintainable code and systems that scale as requirements grow.

I've also participated in numerous hackathons securing Wins and Finalist spots along the way and am currently exploring VR cybersickness mitigation using Unity for my final-year research.

When I'm not coding, you'll find me binge-watching series, painting, doomscrolling, or hunting down the best food spots in town. I also enjoy competitive Scrabble (I won't say I'm a pro, but I can definitely hold my own on a triple-word score.)
