Who I Am

Hi — I'm Gaurav Sharma, a Backend & Cloud Engineer pursuing B.Tech in Information Technology at Indira Gandhi Engineering College, Indore.

I go end-to-end. I write the backend, configure the cloud, and ship something real. My projects aren't just CRUD apps — they include WebRTC peer-to-peer video calling, AWS S3 media pipelines, real-time Socket.IO messaging, and multi-user systems with friend graphs and room management.

Everything I build runs live — behind Nginx, managed by PM2, secured with HTTPS. I care deeply about how systems actually work in production, not just in development.
