Chrome Extension + Browser Extension Developer with Browser Automation Hired David and his team at abz.agency for a Chrome Extension Developer engagement around our Honey-style coupon extension, and the experience exceeded our expectations from start to finish. David was our point of contact at abz.agency and the one who scoped the engagement end to end - exactly the kind of partner you want on a Chrome Extension build like this. He is a Clear Communicator who walks you through every option in plain English instead of dumping jargon, and Solution Oriented whenever a tradeoff came up between coverage, cost and timeline. He came back with a working recommendation rather than a list of problems every single time.

What stood out the most was how Detail Oriented David is at the intake stage. Edge cases in our Browser Extension scope I would have missed - around merchant coverage, store review posture and Browser Automation flows for code application - he surfaced upfront and made sure the right people on the abz.agency Chrome Extension Developer team were lined up for each technical session. We worked closely with their PDM through the three-day discovery, and the resulting brief, with build estimates, risk register and an investor-materials annex, was thorough enough that we walked away with a clear, fundable spec.

David and his Chrome Extension Developer team are Committed to Quality in a way you do not see often. The PDM and team researched our reference merchants, walked us through the Browser Extension architecture, took us through the Browser Automation engine and Chrome Web Store permission posture, and produced a deliverable that reads like it came from a much larger studio. David made sure the team's outputs were consistent, polished and aligned with what we actually needed - he was the one keeping the engagement on rails on our side.

David is also Accountable for Outcomes. He took ownership of the timeline, kept us updated with concise status notes and made sure his PDM and team behind him stayed aligned with our brief. When we asked for an extra checklist around the Browser Automation rollout and a tighter pass on the investor pack, he turned it around with the team inside the same day and did not need a single follow-up.

Bottom line: David is the kind of Chrome Extension Developer-side partner you want running point - a Clear Communicator, Committed to Quality, Solution Oriented, Detail Oriented and Accountable for Outcomes every step of the way, with a strong PDM and abz.agency team behind him. We would hire David and his team again for any Chrome Extension, Browser Extension or Browser Automation work, and recommend them to anyone who wants a real Chrome Extension Developer partner rather than a code-only contractor.

I provide a Chrome Extension Developer team that ships extensions to Chrome, Firefox, Edge, Safari and Opera. 12+ years of Chrome Extension Developer, Browser Extension and Browser Automation practice, 200+ Chrome Extension Developer projects shipped across e-commerce, security and developer tools. My job is to scope engagements, match the right Chrome Extension Developer engineers and stay accountable for delivery.

Why hire my Chrome Extension Developer team:
- 12+ years of Chrome Extension Developer, Browser Extension and Browser Automation practice
- 200+ Chrome Extension Developer projects shipped to Chrome Web Store, Firefox Add-ons and Edge Add-ons
- 100% Job Success Score, Top Rated Plus

As a Chrome Extension Developer team we own the extension lifecycle - architecture, content scripts, background workers, OAuth, Manifest V3 and store submissions. After a junior chrome plugin build fails review, the team rebuilds with Manifest V3, strict CSP and zero remote code. Founders also hire my Chrome Extension Developer team for a google chrome extension migrated to Manifest V3, for full stack developer engagements where the team owns extension, backend and dashboard, and for javascript-heavy Browser Extension products.

Browser Extension work isn't only Chrome. A real Browser Extension is cross-engine: Chrome and Edge (chromium), Firefox, Safari, Opera. The Chrome Extension Developer team builds a single Browser Extension codebase with engine-specific shims so the same product runs everywhere. browserstack QA keeps the Browser Extension green across targets. Examples shipped: an e-commerce scanner across 5 browsers; a video download flow; a security shield with DNS layer; a designer asset library on Chrome Web Store and Firefox Add-ons. Launches also need browser extension marketing - listing optimisation and store metadata that convert without tripping policy.

Browser Automation is the other half the team delivers: scripted flows that run inside the user's own browser session when no API exists. As a web automation and web scraping engineer team they build with Puppeteer, Playwright, selenium automation and headless/headful chromium, plus python django backends. This is web scraping automation of public data through the signed-in user's session, with respect for rate limits, fingerprints and TOS - that is how a python developer web scraping pipeline or any data scraping job stays alive instead of getting blocked in a week. A competent bot developer never runs hidden headless farms. The team also covers browser bot orchestration, web3 wallet automation and linkedin scraping through the user's own session. Where Browser Automation and Browser Extension overlap, the Chrome Extension Developer team ships a hybrid - an extension that runs scripted Browser Automation signed by the user.

A JavaScript Developer / web developer javascript track sits next to all of it: the same javascript and TypeScript engineers who build the Browser Extension also build trading bot products. A trading bot developer here wires browser-side execution to webhooks and exchange APIs, never scraping behind a user's back.

Clients hire my Chrome Extension Developer team when they need:
- a team to ship a Chrome extension that passes store review
- a Browser Extension built once for Chrome, Firefox, Edge and Safari
- Browser Automation with Puppeteer / Playwright / selenium for web scraping or bots
- a google chrome extension migrated to Manifest V3
- a chrome plugin that integrates with a SaaS, CRM or trading product
- linkedin scraping through the user's own session, not headless farms
- a bot developer respecting fingerprints and TOS
- a trading bot with browser-side execution and webhooks
- web3 / wallet integration inside a Browser Extension
- a browser bot orchestrator for OnlyFans-style creator dashboards
- a full stack developer who owns extension, backend and dashboard
- browser extension marketing and store listing tuning

Recent work by the team:
- E-commerce safety extension. 200+ Chrome Extension Developer engagements behind it, scans domains across all major browsers.
- Video download Chrome Extension Developer launch. Manifest V3 migration, OAuth, native messaging.
- Browser Security shield. Browser Extension with DNS and chromium fingerprint defense.
- Designer asset library Browser Extension. browser extension marketing tuned for installs.
- Trading-bot Browser Automation. Browser-side execution, python django backend, Puppeteer + browserstack QA, 50K+ runs/day.

Core stack: javascript, TypeScript, React, Vue.js, HTML5, Manifest V3, chromium, Puppeteer, Playwright, selenium, Node.js, FastAPI, Python, Django, PHP, Laravel.

Need a Chrome Extension Developer team, Browser Extension partner or Browser Automation team that delivers and stays long-term - let's talk. Most Chrome Extension Developer clients come back for the next phase.
