MS Data Science @UCSD

Master's in Data Science at UC San Diego with hands-on experience building ML systems, GenAI applications, end-to-end data pipelines and scalable backend & data infrastructure.

About Me

I'm a Master's student in Data Science at UC San Diego. I transitioned into data and AI to work on problems that scale from building RAG pipelines and LLM evaluation frameworks at Johnson & Johnson to designing data pipelines and REST APIs as a Senior Data Engineer at LTIMindtree.

I care about clear metrics, maintainable systems, and deploying solutions. My work spans GenAI & LLMs, classical ML, backend development, and cloud/MLOps.
