What I'm looking for

I'm looking to contribute to innovative software engineering and machine learning projects, building efficient, user-friendly applications and intelligent systems that solve real-world problems in a collaborative environment.

I've built software for CodeGen International's Lia R&D project and One World Duty Free POS system, using Python, LangChain, Jinja, JavaScript, MariaDB, and Redis. At Square1Ai, I designed Course and Payment Service modules for online education, including multi-gateway payment integration with Checkout.com and PayHere.

I'm completing a B.Sc. (Hons) in Computer Science and Engineering at the University of Moratuwa while building microservices, multimodal RAG systems, and user-facing applications. My work spans Spring Boot, React, FastAPI, Docker, Kubernetes, and cloud deployments, with a strong interest in software engineering and machine learning.
