Sid Abhinav Founder, DeepStack Labs

I help companies build production ML systems: RAG pipelines, fraud detection, ML infrastructure. PhD in Physics. 5+ years shipping ML at startups.

About Me

I'm Sid Abhinav. I run DeepStack Labs, a consulting practice focused on AI/ML systems.

With a PhD in Physics from the University of Florida and 5+ years building ML systems at startups, I've worked across fraud detection, telematics, and RAG/retrieval systems. I've shipped production models that process millions of transactions and built retrieval pipelines that power AI applications.

I work directly with teams. No layers of project managers or junior engineers. Whether you need help architecting an ML system, optimizing an existing pipeline, or just want to talk through your AI strategy, I'm happy to chat.
