Prasad Sankar Prasad-178

Hey, I'm Prasad 👋

Founding Engineer building at the intersection of AI and web3

Building privacy-first AI + web3 infrastructure at a stealth startup — on-device inference, post-quantum cryptography, and zero-knowledge proofs.

On the side, two things I care about:

Opaque — privacy-preserving vector search over encrypted vectors using threshold CKKS homomorphic encryption. 99.8% Recall@10 at 464ms on 1M vectors, on a commodity 8-vCPU AWS box — and 98% recall at 814ms on 2M. Faster at scale than Compass (OSDI '25), RemoteRAG (ACL '25), PPMI, and SANNS (USENIX '20).
Kairo — an on-screen AI tutor for creative software. It watches your screen and teaches you the tool while you use it. It points; you act.

Tech I'm deep in: Agent orchestration, RAG systems, scalable inference, ZK/FHE, and distributed systems
