I want a Google Chrome extension that automatically secures hard-to-get personal-event slots for me. Once I enter the event URL and preferred time range, the add-on should keep checking availability in the background and complete the booking the instant a spot opens—no manual refreshes on my side. Core abilities I need built in: • Calendar integration so the confirmed booking is pushed straight to Google Calendar. • Reminder notifications inside Chrome and, if possible, as push notifications. • Support for recurring bookings (e.g., every first Monday of the month). Please use the standard Chrome Extension stack—JavaScript/TypeScript, Manifest V3, and the Chrome Alarms or Background Service Workers API—to keep the polling lightweight. A small, clear options page where I can set URLs, preferred dates, recurrence rules, and notification preferences would be ideal. Deliverables • Compiled .crx and full source code with comments. • Setup/readme so I can load it in developer mode and later publish it to the Web Store. • Short walkthrough video or screenshots showing the extension detecting an open slot and completing a booking. Acceptance criteria The extension must (1) successfully detect an available slot on a test site, (2) auto-book it without further clicks, and (3) create the corresponding calendar entry and browser notification.

What you need is essentially a fast-response booking assistant inside Chrome, and the real challenge is making the checker lightweight enough to run repeatedly without becoming unreliable. I’d structure it with Manifest V3 background scheduling, configurable recurrence rules, and a simple settings screen so you can manage URL, preferred time window, and alerts without touching code. We handle custom JavaScript/TypeScript work where automation has to be practical, not just theoretically functional. In projects like this, success usually depends on how well the extension handles edge cases on the booking page, how safely it stores preferences, and whether the notification/calendar steps happen cleanly after the slot is secured. A few specifics would be useful before locking scope: - Can you share the test site or at least the booking flow steps? - Should recurring booking mean repeated monitoring for future dates automatically, or cloning the same rules each cycle? - Do you want Chrome notifications only, or should we also plan Web Push/Firebase-style push if the browser is closed?

Hi, The tricky part is the booking moment itself - MV3 service workers get suspended, so I'd drive the polling through Chrome Alarms and keep the click flow resilient to the site's DOM changing. Extensions and TypeScript are everyday work for me; I'd want to see the booking site first to check how it loads slots. Lets get in contact first.
