AI Infrastructure & Product Engineer · India Backend + AI infrastructure at Vault Wealth (Peak XV)
I build the rails AI runs on—and the products that ride them. Previously, I worked on real-time pipelines, vector feeds, and RAG agents at Front.Page (YC S'21).
These are independent products and research projects created and maintained by me.
