Heshani Maddage
AI/ML Engineer
I'm passionate about building solutions powered by AI, turning complex problems into systems that actually work in the real world. I enjoy watching an idea go from a rough concept to something people can use.
About
I am a final year Computer Science undergraduate with a passion for building intelligent, scalable software that bridges artificial intelligence and modern software engineering. My work spans full stack AI/ML systems, LLM powered agent pipelines, workflow automation, and computer vision, complemented by research focused on solving real world challenges through data driven approaches. With a fast learning mindset and cross functional collaboration experience gained through technical leadership, I thrive in transforming innovative ideas into reliable, impactful, and production ready solutions while continuously exploring emerging AI technologies.
