⛰ About Me

Hi! I'm Balachandra, a graduate student at UMass Amherst who loves turning ideas into polished, working software. I care about clean architecture, thoughtful details, and building things that actually feel good to use.

When I'm not coding, I'm usually outdoors, sketching something, or tinkering with side projects like this one.

By training, I'm a machine learning researcher and software engineer with 2+ years of experience spanning product engineering and applied AI. My M.S. work at UMass focused on LLMs, retrieval, and efficient ML systems, including research on controllable memory for LLM agents, RAG pipelines, and edge inference, I'm drawn to questions about how models behave and how to make them genuinely useful in the real world.

Before grad school, I spent time at Epsilon building backend systems and data pipelines that needed to just work at scale, and more recently I've been a Graduate Research Extern at Microsoft exploring memory frameworks for LLM agents. What excites me most is the space where solid engineering meets real research, that's usually where the interesting problems live.
