Hire the Best Browser Extension Freelancers
in India

You get a Chrome extension or browser automation built to last, not just to demo well once. Proof: 10 completed jobs, five stars on every one, 100% Job Success. Whether you need a broken extension fixed, a new one built on Manifest V3, or a repetitive browser task automated, autofill, data extraction, Trello-style workflow tools — you get someone who's shipped exactly that kind of work, not someone learning on your dime. Not sure if this should be browser-automated or handled through an API? You'll get a straight answer and the reasoning behind it, before you pay for the wrong one. Need an AI feature? You get answers grounded in your actual data instead of a model guessing, the same document-chat and semantic-search pattern powering two of my own live products, Chat with Anything and AI Engine. • A Chrome extension built right the first time, or fixed fast if it's already broken (Manifest V3) • Trello workflows turned into one-click checklist/label automation, proven across 5 completed contracts • Browser automation that survives real-world use, retries and error-recovery built in, not a fragile script • AI features that answer from your real data, document chat, semantic search You're also getting 8 years of Amazon engineering discipline behind every build (SDET II, across Kindle, Alexa, Physical Stores), part of why what I ship is built to survive real usage, not just look good in a demo. Whatever you hire me for, expect it to still be running unattended months or years later, that's the bar, not the exception.
