About
Me.
Hello! I'm Srishan Mandawala — a passionate Software Engineer based in Galle, Sri Lanka. My journey in software development started with a curiosity about how things work on the internet, and it has since evolved into a deep passion for building intelligent, AI-powered applications.
Today, I specialize in full-stack development and Generative AI, building modern applications using technologies like React, Next.js, FastAPI, and LangChain. I'm passionate about Retrieval-Augmented Generation (RAG), NLP, and creating solutions that bridge the gap between cutting-edge AI and practical user experiences.
