Chrome Extension Developer (LinkedIn Tool) – Remote

RedditJosephh (R)NigeriaFreelance

About the Company

An individual finance professional is building Reach, a Chrome extension designed to help people network more effectively on LinkedIn. The product is fully specced with an 11-section product document ready for serious applicants.

Job Description

The developer is needed to build a Chrome extension that automates a manual LinkedIn networking workflow. When a user visits a LinkedIn profile and clicks a button, the tool will instantly provide a verified email address and an AI-drafted outreach message, then auto-log the contact to a CRM dashboard. The goal is to replace a 30-minute, multi-tool process with a 90-second workflow.

  • Project: Chrome Extension "Reach" for LinkedIn
  • Location Type: Remote
  • Timeline: 6 weeks
  • Budget: $1,500–$3,000 fixed price (not hourly)
  • Payment Structure: 25% upfront / 25% working prototype / 25% full integration / 25% final delivery

Key Responsibilities

What Needs to Be Built

Chrome Extension (Manifest V3)

  • Detect LinkedIn profile pages.
  • Read name, title, and company from the visible DOM (no scraping).
  • Call the backend to hit Hunter.io for a verified email.
  • Call the Claude API to generate a personalized outreach draft.
  • Display results in a popup UI.
  • Auto-log the contact to Supabase on send.

Backend API (Node.js or Python)

  • Handle all third-party API calls (Hunter.io, Claude).
  • Manage user credits and authentication.
  • Write to the Supabase database.
  • Send reminder emails via SendGrid.

Note: The React dashboard is being built separately. The hired developer is responsible for connecting the extension and backend to it, not building the dashboard from scratch.
