Senior Full-Stack Engineer

Pratyush Mahapatra

I lead Product Engineering at G5 AI Studio, and design, build and animate products across the full stack.

About

I enjoy working where product complexity meets frontend engineering: realtime state, large media assets, collaborative interfaces, data-heavy visualizations, and AI workflows.

I'm a Senior Frontend Engineer with 5+ years of experience building complex SaaS and enterprise applications with React, Next.js, and TypeScript. I specialize in frontend architecture, real-time applications, performance optimization, data-heavy interfaces, and AI-powered products, with strong full-stack depth across backend, cloud, and distributed systems.

At Collective Artists Network (Galleri5), I lead frontend development for G5 AI Studio, an enterprise generative-AI filmmaking platform. I own frontend architecture, lead a 3-engineer frontend team, and contribute across the full stack while collaborating with directors, producers, and Microsoft's ISE team. The platform supports real production workflows for feature films, episodic series, and AI-enabled micro-dramas, with real-time AI generation, asset management, review workflows, and multi-model orchestration.

Beyond product engineering, I've trained a 50-60M parameter language model from scratch, built video analytics systems at Gumlet, and delivered healthcare workflow platforms from scratch.
