What I'm looking for

I’m looking for a product-first role where I can combine AI/ML thinking with backend execution—turning user insights into shipped features, improving retention and latency, and delivering measurable outcomes through rapid iteration.

I’m a product management intern and AI/ML-focused product engineer who thrives at the intersection of user research, shipping, and measurable growth. At Physics Wallah, I owned the end-to-end launch of the PW Games application, ran 200+ user interviews to pinpoint friction points, and improved Month-1 retention through targeted onboarding iterations. I also helped drive 2,000+ paying users in the first month post-launch with zero active marketing spend through product-led growth.

Previously, I led the Job Studio MVP from zero to launch at Roobaroo.ai—owning product scoping, Java + Spring Boot backend architecture, and cross-functional delivery with sub-200ms API latency. I’ve also built AI systems and product prototypes like a multi-agent resume enhancer that reduces manual tailoring time by 70%, a LangChain-based medical chatbot/report analyzer, and privacy-first experiences with encrypted storage and NLP sentiment tagging. I’m motivated to keep turning ambiguous problems into reliable products through crisp execution and data-backed iteration.
