About

A student engineer obsessed with shipping clean, scalable systems.

I'm Mayank Raj, a Software Engineering student at Scaler School of Technology, pursuing a B.Sc. in Computer Science with BITS Pilani.

I build resilient backend systems and explore where AI engineering meets product. My work lives at the intersection of distributed architectures, data, and developer experience — shipping fast without giving up on craft.

Currently focusing on:

DSA
Backend Development
System Design
AI Engineering
