About Me

I'm Joseph Rodrigo — a software engineer from Colombo, Sri Lanka, currently working at Innovation Quotient Pvt Ltd. I build full-stack web and mobile applications, integrate APIs, and design scalable systems that ship. My work spans React, Next.js, .NET Core, Flutter, and Python.

I'm actively exploring AI and machine learning — my final-year project is an AI-driven Sinhala MCQ generator using RAG pipelines, LangChain, and Neo4j. I work async-friendly with clients worldwide and thrive on projects that demand both technical depth and creative problem-solving.
