Full Stack Engineer building production AI systems that serve real businesses at scale.
At Modelia, I work across the full AI product platform — generative image engine, merchant-facing app, Studio, and internal tools. Previously built AI-powered hiring automation at Asynq, a university LMS serving 5K+ learners at CCS University, and defence infrastructure at Bharat Electronics Limited.

Uptime
I build and ship AI systems that serve real businesses. With experience spanning defence infrastructure, AI-powered hiring automation, and generative AI platforms, I focus on systems that stay alive at 3am and code the next engineer can read.
My focus is on building systems that are not just functional, but maintainable, scalable, and production-ready.
