I already have a functional Amazon A-to-Z shift-grabber, but it only works reliably when the window stays in the foreground and its reaction time is too slow to beat other workers. I’d like you to overhaul the code so it can operate unseen in the background and lock in blocks at the very first moment they appear. Performance upgrade • Cut response time to the absolute minimum—ideally within the same second a shift is posted. • Streamline the logic or API calls so the tool stays stable even when Amazon’s listings spike; no freezing or missed updates. New functionality • Build an automated selection engine: after I set rules such as station, day of week, start/end hours, or minimum pay, the script should claim any matching shift automatically without further input. Acceptance criteria 1. A demo showing the grabber running head-less or minimized while another app is in focus, still securing test shifts faster than the current version. 2. A configuration file or simple UI where I can edit my preference rules. 3. Clear, well-commented source and a brief README so I can tweak it later. Whatever language or framework the existing code uses is fine—as long as the upgrade is clean, efficient, and future-proof.

Hi there, You need the Amazon A-to-Z shift grabber rewritten to run head‑less, react within seconds, and auto-claim by rule , I’ve upgraded similar automation to background services and low-latency listeners, so I’ll shave your reaction time and make claims reliable under listing spikes. - Deliver a head-less/background grabber that secures test shifts within the same second they appear (demo provided). - Deliver an automated selection engine with rule set: station, weekday, start/end, minimum pay (config file + simple UI). - Deliver full source with clear comments and a concise README for future tweaks. - Risk/control: staged rollout, unit/integration tests, logging, and a rollback plan if Amazon behaviour changes. Skills: ✅ PHP ✅ JavaScript ✅ Automation (background/headless services) ✅ Deployment: daemon/cron, container or Windows service ✅ Reliability: rate-limiting, retry/backoff, logging Certificates: ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ cPanel® & WHM Certified CWSA-2 I’m available to start immediately. Do you want the grabber implemented as a headless browser service (Puppeteer/Playwright) or a lightweight API/agent combo (Python daemon + JS frontend) — which fits your current codebase better?

I already see a clean way to execute this. I specialize in browser automation and bot scripting specifically for platforms like Amazon, including maintaining reliability even when the window isn’t in focus or actively visible. I’ve upgraded similar “shift grabbers” before so they keep running in the background without random failures or needing constant manual oversight. You want your existing Amazon A-to-Z shift grabber to be more stable, run hands‑off, and keep grabbing shifts reliably without depending on the active window. In simple terms: same tool, same result, but smarter, smoother, and less babysitting from you. My approach would be to harden the current logic, improve how it interacts with the page (so it doesn’t rely on focus), and add light monitoring so you know it’s working without having to watch it. Quick question: is your current grabber running as a browser script/extension or a standalone app? Lets chat more about your project, worst case you walk away with a free strategy session Regards

Hi, I’ll rebuild your shift-grabber to run fully in the background and lock shifts instantly (sub-second response) by removing UI dependency and optimizing request handling. I noticed your current issue likely comes from foreground-bound execution and slow polling/response cycles—this is why it loses against faster tools. I’ll convert it into a headless, event-driven or ultra-fast polling system with parallel processing. My approach: • Refactor to headless/background execution (no focus required) • Optimize API calls + introduce concurrent requests for near-instant detection • Build rule-based auto-claim engine (filters: station, time, pay, etc.) I’ve built high-performance automation systems that reduced response times by 40–60% and handled high-load scenarios without missing events. You’ll get a working demo, clean code, config/UI for rules, and a clear README. Initial optimized version can be ready in 2–4 days. Can you share your current codebase or tech stack so I can suggest the fastest upgrade path? Thanks.
