Sarthak Singh

Skilled in building scalable and distributed systems.
I build LLM-based RAG pipelines and tools for automation.

I am a Master’s in Software Engineering student at the University of Maryland, graduating in December 2025. I previously worked as a Software Engineer at IBM India Labs and as a full-stack developer for Influenced (US startup). I specialize in Python, Golang, Kubernetes, AWS, FastAPI, and high-performance backend systems. I enjoy sports, outdoor activities, and working on AI automation projects.
