You will get a React Chrome Extension with API Integration for your SaaS

Project details
Looking for a professional developer to build a robust Chrome Extension? I specialize in creating high-quality SaaS products and Automation Tools using React and TypeScript.
I build software. My extensions are built on Manifest V3 (Google's latest standard), ensuring they are future-proof, secure, and ready for the Chrome Web Store.
✅ What I Can Build:
SaaS Products: Complex extensions with User Auth, Stripe payments, and Database integration.
Workflow Automation: Bots that fill forms, click buttons, and navigate pages for you.
API Integrations: Connect your browser to OpenAI (ChatGPT), CRMs, or custom backends.
💻 My Tech Stack:
Frontend: React.js, Tailwind CSS, HTML5
Logic: TypeScript (for type-safe, scalable code)
Backend: Node.js, Firebase, Supabase (if required)
🚀 Why Choose This Gig?
Clean Code: I use TypeScript to prevent bugs.
Modern UI: Professional interfaces that look great.
Ownership: You get 100% of the Source Code.
Let’s turn your idea into a browser reality. Choose a package to get started!

About Usama
Full Stack Extension Developer proficient in TypeScript and React
Hyderabad, Pakistan - 12:42 pm local time
I currently build and maintain a 12-module Manifest V3 downloader suite in TypeScript/React 19 - the flagship extension has 18M+ downloads. I designed a shared headless URL-to-MediaSource resolve engine so each new platform integration stays a thin adapter, built a scaffolding CLI with CI drift detection to speed up new-module setup, and reverse-engineered YouTube's Innertube API into a two-request, cookie-free 4K extraction path.
Previously, I built a Manifest V3 Chrome extension for digital wellness, including a real-time feed-interception engine processing 50,000+ DOM elements/second with zero main-thread impact, and a privacy-first local storage architecture handling 100MB+ of data with no server dependency.
On the full-stack side, I've built a Next.js contract-creation wizard that cut contract creation time by 90% for a small team, and led a 3-person team building an LMS on Next.js/Prisma with a 15+ model schema and AI-assisted assessment evaluation.
I also maintain a few open-source projects, including a Chrome accessibility extension with 44 automated tests in CI/CD and a Puppeteer-based job-application automation tool.
I write clean, tested TypeScript and I'm comfortable owning a feature end-to-end - from Chrome APIs and content scripts to React UI and backend integrations. Happy to talk through your project and what it needs.
