ENGINEER BY CURIOSITY.

Singh Rajora.

I build systems.
I like knowing where they break.

An IT undergraduate at IIIT Lucknow, exploring the space between backend engineering, security, and really good problems.

Less talk.

A couple of projects that explain
how I think, better than a bio can.

NODE PLACEMENT

Same hash. Same content. One object is enough.

Split the input into content-defined chunks.

Sample data, not a benchmark. Physical multi-node copying is simulated.

DFMS

DISTRIBUTED SYSTEMS

A file is just the beginning.

A Go storage system that breaks files into content-defined chunks, avoids storing duplicates, and explores how data should be placed across nodes.

REAL-TIME WEB

Your skill. Someone else's next step.

A team-built platform for exchanging skills. I owned the backend and real-time systems: persistent chat, multi-tab delivery, and video-call integration.

02 / BEYOND THE BUILD

A healthy appetite
for hard problems.

Sometimes I build things.
Sometimes I try to break them.

03 / THE PERSON BEHIND THE CODE

Curiosity is
the common thread.

The parts you don't see are usually the parts I find most interesting.

I'm studying Information Technology at IIIT Lucknow. My work moves between backend systems, security challenges, and open source. Different problems, but the same instinct: understand what's happening underneath.

Outside my own projects, I help build the technical community at Axios through hands-on sessions, open-source initiatives, and CTFs.
