What I'm looking for

I’m looking for a role where I can build full-stack MERN products, integrate AI into real workflows, and own secure authentication plus performance-focused backend and frontend improvements.

I build full-stack MERN applications that turn uploads into decisions—like an AI-powered interview preparation platform that processes 1,200+ resumes monthly using Gemini AI for automated scoring and fast interview question generation.

I’ve worked end-to-end on authentication and protected APIs, adding token-based auth with role-based access across user tiers, plus versioned endpoints for analysis history and audit-ready tracking.

I also ship production-style frontends and performance improvements with React (hooks, memoization) and reliable backends with Node.js/Express, RESTful services, and optimized MongoDB schemas using compound indexing.
