About this gig

A Manifest V3 Chrome extension for your team, living where they already work: the browser.


I've shipped 60+ releases of a Chrome extension used daily by sales teams: uploads, page capture with automatic pagination, screenshot OCR, and a compose tool that talks to a backend API. Yours gets the same build discipline: Manifest V3, least-privilege permissions, tests, and a handover your developer can maintain.


What you send

- What the tool should do, in plain words, and on which sites

- Your API, if it needs to save or fetch anything

- Who uses it: your team (unpacked install) or the public (Web Store)


What you get

- Full source, MV3, no unnecessary permissions

- Popup, content scripts, options page, background sync or browser automation as needed

- Two builds if you need them (production and local test)

- Install guide for your team, or a complete Web Store submission package

- Tests for the logic and a manual checklist for the UI


Ground rules: no scraping behind logins the user does not own, no data collection beyond what the listing states, no permissions the tool does not need. Message me with what it should do before ordering and I'll confirm feasibility and the package.

Mention a first customer bonus and get substantial discounts on your project! I turn messy data into systems that run themselves. 7+ years in healthcare, aviation, and retail: PostgreSQL databases holding millions of records, Python ETL pipelines that clean, deduplicate, and sync data across platforms daily with no hands on it, and reports that give leaders answers instead of spreadsheets. I build database schemas, automation, API integrations (CRMs, Mailchimp, SMS), and dashboards your team can actually maintain. Tell me the problem and I'll map the fix before you commit.
