DeSilva S
GenAI Engineer / AI Developer at Tata Consultancy Services (TCS)
Developing production-grade GenAI systems focusing on LLM fine-tuning, Agentic AI, and RAG at TCS.
Intro
I'm DeSilva S, a GenAI Engineer at TCS specializing in building production-grade AI systems. My journey has taken me from deep-diving into medical data summarization during my internship to fine-tuning LLMs and developing Agentic AI at scale. I’m passionate about moving beyond simple 'prompt experiments' to create reliable, grounded products that solve real-world problems. Outside of the technical stack, you'll likely find me capturing macro shots of wildlife, training for my next marathon, or geeking out at Comic Con. I'm always looking to collaborate on applied LLM systems or offer my expertise as a GenAI freelancer to help teams turn AI demos into robust solutions.
