COFFEE FIRST

Rajdeep
Chaudhari.

I'm a Computer Science graduate in London who builds small honest software, represents colleagues as a union rep, and thinks Demon Slayer is genuinely underrated.

First Class BSc from UEL, May 2026. I'm focused on GRC and cybersecurity — governance, risk, compliance, the layer where policy meets engineering. Currently studying CompTIA Security+ and working through ISO 27001 and NIST CSF on the side.

The Work

Built, not just talked about
● LIVE 01

Webnite

Game-based CompTIA Security+ training

A pixel-art narrative game that teaches CompTIA Security+ SY0-701. Covers threats, risk management, cryptography, and network security through short lessons and hand-built minigames — because flashcards shouldn't be the most interesting study tool we have.

Patchbay

Browser-to-browser audio pipe

WebRTC audio routing between two browsers. Opus HD or lossless PCM. No install, no backend, no cloud. A weekend build that turned into a reliable little utility.

The Human

Who's behind the page

I grew up taking things apart to see what was inside, and I never really grew out of it — just swapped the screwdriver for a terminal.

I moved from India to London for university in 2023. Since then I've been quietly assembling a strange but coherent life — a retail job, a union role, a mentoring gig, some software projects on the side, and a Computer Science degree holding it all together.

I'm drawn to cybersecurity, especially the GRC side — policy, controls, risk, the bits where the human and the machine have to agree on the rules. It rhymes with the union rep work, which is funny.

Outside all that, I like making small tools that respect the person using them — no tracking, no dark patterns, no "we've updated our terms" emails. If you use Voxlit or Patchbay, no server of mine knows about it.

Let's
talk.

I like meeting people who care about the thing they're working on. Drop me a line about a role, a project, a book recommendation, or just to say something nice about Voxlit. I reply to almost everything.
