# Rajveer Singh, the plain version > Everything on the site as facts: work, projects, record, stack, contact. ## Experience - **IABTM**, Software Engineer (internship), Sep 2025 to now. Building the core of a US self-improvement platform. Rebuilt its live voice rooms on an SFU, rebuilt its Stripe billing so no one is charged twice, and built the daily AI pipeline (Gemini) that curates what each member reads. Also built the email and the team’s admin tools, and runs the AWS. - [Inside the voice rooms and billing](https://rajveers.com/projects/iabtm) - **Wii Hop**, Software Engineer (contract), Jul 2025 to May 2026. Built most of the web app for a US local-deals startup: deals on a live map, table booking, events, loyalty streaks, and heists that turn a night out into a game (React, TypeScript, Leaflet). On the backend, wrote the parts where money and stock change hands, from the heist item shop to catering orders priced on the server. Also built screens for the Expo app. - [Inside the deals, bookings and loyalty](https://rajveers.com/projects/wiihop) - **Modulus**, Frontend Engineer (internship), Apr 2025 to Aug 2025. Built the product’s interface from the first screen: cohort pages, booking and payment on Razorpay, scheduling through Cal.com, and live sessions with chat running beside the stream (React, TypeScript, hls.js). Wired PostHog funnels so the team could see where people dropped off before they enrolled. - [Inside booking and live sessions](https://rajveers.com/projects/modulus) ## Every project ### [IABTM](https://rajveers.com/projects/iabtm) The core of a US self-improvement platform: live voice rooms, Stripe subscriptions, a daily AI pipeline and the AWS it runs on. - internship, Sep 2025 to now.
