I will build a custom chrome extension for automation or web scraping


About this gig
Every site has something it won't do. A button that isn't there, data locked in a table you copy by hand, a form you fill in fifty times a week. An extension fixes that.
I build Chrome extensions on Manifest V3, so what you get keeps working instead of breaking at the next browser update.
What I build: scrapers that pull page content into CSV or JSON, popup tools, content scripts that change how a page looks or behaves, form autofill and bulk actions, right-click menu tools, and background workers for scheduled jobs.
Everything gets tested before it reaches you. I load it into a real browser, run it against real pages, and check the edge cases that bite: duplicate rows, missing fields, CSV that breaks Excel. My last build passed 21 checks before delivery and I'll show you the output.
You get the full unpacked source, a guide for loading it, and notes on what each file does. Nothing is minified or locked, and the code is ready for the Chrome Web Store.
I'm a computer science student, not an agency. You deal with me directly, and bugs in what I deliver get fixed free.
Tell me what the site won't do and I'll tell you honestly whether an extension can fix it.

FAQ
Will this work in Edge or Brave?
Yes. Both run on Chromium, so the same extension loads in either one. Firefox needs a small manifest change, which I can do if you ask up front.
Can you publish it to the Chrome Web Store for me?
I build it store-ready, but the listing has to be published from your own developer account, which costs a one-time 5 dollar registration. I'll walk you through the upload.
Do you need my login for the site?
No. I build against publicly reachable pages or a sample of the page HTML you send me. I never ask for your credentials.
