You will get a cross‑browser React extension for Chrome, Edge & Firefox
Project details
Do you need a reliable browser extension that works across Chrome, Edge, and Firefox, without dealing with Manifest V3 and complex APIs yourself?
I will design and build a production‑ready browser extension using React and modern WebExtension APIs. The extension will be cross‑browser compatible, following best practices for performance, permissions, and security.
What you will get:
UI built with React (or plain JS if preferred), tailored to your use case (scraping, productivity, dashboards, integrations, etc.).
Cross‑browser setup for Chrome, Edge, and Firefox using the WebExtension/Manifest V3 standard.
Core features wired to your API or backend (REST/GraphQL, Supabase, AWS, or custom Node/FastAPI services).
Clean, well‑structured code and instructions on how to build, load, and publish the extension.
Tech stack (depending on your needs): React, TypeScript, JavaScript, WebExtension APIs, Manifest V3, Supabase or AWS (Amplify/Lambda) for backend and auth.

Worked really well on the multiple projects he was involved with. He adapted well to change and was excellent at picking up new skills in the AWS infrastructure space that were required for AWS Amplify deployments.
