// About

Full-stack developer for web & mobile.

I build real-world applications with auth, role-based access, REST APIs, databases, payments and deployment — with practical Generative AI features where they actually help.

SDE Intern Full-Stack MERN · Next.js

I'm Mohan Vignesh, a Full Stack Developer based in Visakhapatnam, India.

I work across MERN, Next.js and React Native. Currently a Gen AI Intern at Sariki Technologies working on the FarmTally Next.js app, and previously a MERN Stack Intern at Headway Vision on Study Abroad projects. I'm actively looking for Software Developer Internships where I can contribute across the stack. I care about clean access control, server-authoritative state, and apps that hold up under real load — with practical GenAI features where useful.

Full-stack engineering

React and Next.js frontends, Node + Express APIs, JWT with role-based access — owned end to end, from schema to deployment.

Web & mobile apps

Next.js web apps and React Native mobile apps with Firebase — timetables, productivity flows, dashboards, and clean, usable interfaces.

Deployed, not demoed

College-used exam platform for hundreds of concurrent students, a cross-platform study app, and a franchise system with payments and invoicing.
