AI Product Engineer — leading AI product direction and shipping generative AI products that drive real business growth.

At Modelia, I lead AI product direction for the generative image & video platform — building the AI video production pipeline, unifying platforms, and shipping features that move revenue. Previously built AI-powered hiring automation at Asynq, a university LMS serving 5K+ learners at CCS University, and defence infrastructure at Bharat Electronics Limited.

About

Building AI productspeople actually use

I lead AI product direction and ship the code behind it. With experience spanning defence infrastructure, AI-powered hiring automation, and generative AI platforms, I focus on products that drive measurable business growth — and systems that stay alive at 3am.

My focus is on building systems that are not just functional, but maintainable, scalable, and production-ready.
