Kushagra Bharti

I’m a Backend Engineer focused on building production-ready applications with Express.js. I specialize in RESTful APIs, authentication with JWT and Nodemailer, data management using Node.js and MongoDB, and real-time communication with Socket.io.

In my current role at Medoc Health IT Pvt Ltd (Medoc Health IT Pvt Ltd), I worked on Mplus—managing and maintaining structured data for phlebotomists, nurses, and pharmacists to support smooth healthcare operations. I designed and optimized backend workflows for staff onboarding, profile management, and role-based data access, and built features for termination, resignation, financial records, and form-based data to ensure lifecycle and compliance tracking.

I also build strong backend products through projects like Diffy (AI-Powered Code Reviewer), where I created an AI-based system to analyze code and generate automated reviews, and implemented validation to detect errors and improve code quality. With AuthNexus, I built secure authentication (registration, login, logout), OTP verification via email using Nodemailer, JWT session management, and protected routes with token verification middleware.

Across my work, I prioritize reliable data synchronization and system stability, plus clean API design and secure access patterns. I’ve deployed and supported applications using Render, Vercel, and Cloudinary, and I published research on “BNest: Advancing Personalized E-Learning with Scalable Solutions Using TypeScript and MERN Stack”.
