At Material, I ship production features for an enterprise GenAI platform and community research SaaS using an AI-native workflow. I owned the frontend conversation experience for Muse, where moderated focus groups run with orchestrated AI personas, and built UI for SamurAI, a document-grounded RAG assistant.

At Ekanek Networks Pvt Ltd, I owned architecture and delivery for Foxy and AppX, a multi-tenant white-label platform that cut new-brand onboarding from two weeks to three days. Earlier, I led development of Together For Her at Avegen Healthcare Pvt Ltd and built products across healthcare, fintech, e-commerce, and community research.
