# About Harjot Singh Rana

> A full-stack engineer and AI engineer in New Delhi, open to contract and full-time work, who takes early-stage products from a rough idea, a Figma, or a half-built codebase to something live and maintainable.

## Who I am

Harjot Singh Rana is a full-stack engineer and AI engineer based in New Delhi, India. He is available for contract, freelance, and full-time roles, remotely from India.

I'm Harjot Singh Rana. I work with TypeScript and Python, and I ship multi-agent AI products, multi-tenant SaaS, real-time backends, and developer tooling end to end: the product surface, the API, the data model, the billing, and the unglamorous production hardening in between.

This site is the canonical public record of that work. Every claim on it resolves to something you can open: a live product, a repository, a package, a post, or the [résumé](/resume.pdf).

## What I have shipped

- [The Whiskey Library](https://whiskeylibrary.com): e-commerce full-stack developer since August 2026. I build the Shopify storefront, the subscription backend on Recharge, and customer tools such as the subscription dashboard and the taste-profile quiz.
- [Helicon](https://helicon.sh): an open-source desktop app and VS Code extension for Meta's Muse Code CLI (unofficial). 3,500+ installer downloads and 88 GitHub stars within five weeks of the first commit.
- [Moonshift](https://moonshift.io): founding engineer on an AI app builder. I rebuilt the multi-agent generation pipeline, raising end-to-end success from 46.2% to 76.7% and cutting median prompt-to-live time 32%, for 1,200+ users generating 800+ apps.
- [Reinstate](https://reinstate.dev): an open-source Go CLI for encrypted, cross-machine Claude Code and Codex session continuity, with 23/23 cross-platform acceptance tests passing.
- [FixedLaunch](https://fixedlaunch.com): a fixed-price rescue service for broken AI-built apps. Founders get a bug video and a written fix plan within 48 hours of access.
- [Brio UI](https://brioui.com), a library of 50 interaction-first React components, and [Swoopcut](https://swoopcut.com), a pipeline that records a live web app and renders a 60 fps launch clip.

The full list, with stack and outcomes, is on the [projects page](/projects).

## Background

B.Tech in Computer Science and Engineering from Guru Tegh Bahadur Institute of Technology (GGSIPU, New Delhi), 2022 to 2026. Before Moonshift I was a full-stack engineer at SignVault.io, a multi-tenant e-signature SaaS where I owned the REST API, the ABAC permissions engine, and Stripe billing. Earlier I was a software engineering intern at LawSikho, where I built a multithreaded Python pipeline that scraped and deduplicated 100,000+ job listings, and a full-stack intern at Mindcase.

Recognition that other people can check: a $10K Avalanche ecosystem mini-grant (one of 10 teams selected across India), a top-120 finish out of 20,000 participants in the OpenCode Buildathon, and 770+ problems solved on [LeetCode](https://leetcode.com/u/HarjjotSinghh).

## How I work

I work remotely with founders, operators, and small product teams on contract, freelance, full-time, and fractional engagements. Every engagement starts with a written scope that says what is included, what is not, and what happens when that changes. The ways I can help, and the process, are described on the [work with me](/hire) page.
