Hi, I'm Rajveer Singh!

Software engineer in New Delhi, building AI products end to end: the interface people touch, the backend and realtime underneath, and the infrastructure that keeps it up.

At IABTM, a US self-improvement platform, I rebuilt the live voice rooms on an SFU and the Stripe billing, and built the AI pipeline that picks what members read each morning. That code lives in private repos and is committed from the company's account, so it doesn't show on the graph below. The write-up, with the architecture, is on my site.

Things I've built

Project What it is
HyperPersona An agentic personalisation engine on AWS Bedrock that learns why a shopper buys. Cognizant Technoverse 2.0 finalist, top 24 of 5,600+ teams. Code
Safire A harassment shield for LinkedIn DMs, first at HackWIE 3.0 and Code Kshetra 2.0. I built the backend: the API, moderation that fails over, and PDF evidence reports. Code
Kernel Anonymous chat rooms with peer-to-peer voice, where the server only relays the WebRTC handshake. Code
10xAnswers A drop-in React chat widget that answers your visitors with AI, 13,000+ downloads on npm. Code
The AI me An AI version of me on my site that answers for my work, shows its sources and runs evals every night.
IEEE MSIT The chapter's website, kept current by a bot that turns its Instagram posts into events. Code
