Amazon Hiring Browser Extension
A Manifest V3 Chrome extension for real-time job-shift discovery and end-to-end booking across multiple accounts — fully client-side, with no server, proxy, or backend of any kind.
A Manifest V3 Chrome extension that detects and books high-demand job shifts in real time, across multiple accounts, entirely within the user's own browser. There is no server and no proxy — the constraint that shaped the whole design — so all detection, account handling, and booking logic runs client-side.
The hard part is speed under a strong anti-bot layer: the extension uses a tuned burst-and-cooldown polling ladder and a managed-popup plus page-bridge technique to carry anti-bot tokens through to the booking request. Delivered over six milestones with a warranty and full source handover.
Case Study
The Problem
The client needed sub-second detection and immediate booking of high-demand job shifts that appear and vanish in seconds, across more than one account, running entirely inside their own Chrome browser. No server and no proxy was a hard requirement — everything had to live in the extension itself — while still being fast and reliable enough to win shifts against a strong bot-detection layer.
The Approach
Built a Manifest V3 extension with multi-account drop-and-pickup handling and a polling strategy tuned against the site's bot-detection limits using a burst-and-cooldown ladder, since sustained sub-second polling from a single residential IP is structurally detectable. Used a managed hidden popup plus a MAIN-world page bridge to carry the site's anti-bot token correctly through to the booking request, then drove the full booking flow end to end — all without any backend. Delivered across six milestones with a warranty period, full source at handover.
The Outcome
Delivered a fast, fully client-side booking extension running across multiple accounts with no infrastructure to maintain. Shipped across six milestones with a bundled warranty; full source and repository handed over, and the client left a five-star review.
