Harshit Gangwar

I’m a B.Tech in Computer Science student focused on building scalable full-stack products with secure APIs, performance-minded architecture, and a strong AI orientation. In my recent internships, I developed full-stack applications with Next.js, React, Node.js, Express, and MongoDB, ensuring smooth frontend-backend communication and an optimized user experience.

I’m especially proud of the security and reliability work I’ve delivered: implementing authentication and authorization with JWT, HTTP-only cookies, OTP verification, password reset flows, protected routes, RBAC, CORS, and API rate limiting. I also engineered modular backends using Redis caching, Cloudinary integration, Zod validation, centralized error handling, Winston logging, and MongoDB query optimization to improve maintainability and performance.

On the AI and product side, I built Campus Pulse for fast college ID verification, using ML Kit in an end-to-end verification pipeline to reach 95%+ accuracy while cutting false rejections and manual effort. I also created AI-driven projects like SkillForge (resume generation, mock interviews, AI roadmaps), VOX HIRE (voice recruiting with Gemini evaluation), and GitPal (a Gemini-powered developer CLI published on npm)—all designed with deployability, scalability, and clean workflows in mind.
