Amazon Shift Sniper: High-Frequency Automation Chrome Extension - Dominate high-frequency booking workflows with zero downtime by Pasindu Piumal

Amazon Shift Sniper: High-Frequency Automation Chrome Extension

Dominate high-frequency booking workflows with zero downtime. I engineered "Amazon Shift Sniper," a resilient, high-performance Manifest V3 browser extension built for real-time monitoring and automated slot booking.

To bypass rigid security headers and CSRF requirements, the engine uses a dual-layer strategy interacting across both Isolated and Main script worlds. It features a robust session interception system that discovers and inherits valid tokens dynamically. It includes a sophisticated 403 error auto-cooldown bridge and direct DOM configuration injection.

Amazon Hiring Automation: Custom Chrome Extension with OTP & AI-Sync - Eliminate login friction with advanced, human-like browser automation by Pasindu Piumal

Amazon Hiring Automation: Custom Chrome Extension with OTP & AI-Sync

Eliminate login friction with advanced, human-like browser automation. I engineered "AutomatePro," a Manifest V3 Chrome extension designed to bypass complex authentication bottlenecks on Amazon’s hiring portal. This isn't a simple script; it’s a robust automation engine featuring Human Emulation (simulated typing/clicks) and Smart OTP Retrieval via API bridges or direct Gmail DOM scanning.

To ensure reliability, I implemented a CAPTCHA Safety Lockdown and a persistent Service Worker keepalive.

Amazon Shift Availability Monitor: Real-Time Web Scraping Engine - Never miss a high-demand slot to rate-limiting by Pasindu Piumal

Amazon Shift Availability Monitor: Real-Time Web Scraping Engine

Never miss a high-demand slot to rate-limiting. I developed a high-frequency availability monitoring Chrome Extension (Manifest V3) that tracks real-time shift openings on Amazon hiring platforms.

Built with a React interface and a resilient background service worker, the extension polls target pages every second for specific "No Headcount" errors without triggering anti-bot flags. Crucially, I engineered a 403 CloudFront Recovery system that automatically pauses execution for 60 seconds upon detecting an IP block, ensuring continuous, long-term operation without detection.

Amazon Portal Session Recovery: URL Auto-Repair Chrome Extension - Eliminate candidate drop-off caused by broken web sessions by Pasindu Piumal

Amazon Portal Session Recovery: URL Auto-Repair Chrome Extension

Eliminate candidate drop-off caused by broken web sessions. I engineered an intelligent URL Auto-Repair Chrome Extension (Manifest V3) designed to detect and programmatically fix "Timeout," "404," and "No Shift Available" loops on Amazon’s recruitment platforms.

Built with React and Tailwind CSS, the extension uses the Browser History API to preserve query parameters while executing surgical redirects. To ensure high reliability, I designed a custom 1-minute cooldown retry loop and a smart DOM-polling mechanism that checks for specific error banners before modifying states—preventing refresh.

Amazon Real-Time Slot Tracker: High-Fidelity Data Extraction Tool - Unlock hidden workforce insights with real-time data synchronization by Pasindu Piumal

Amazon Real-Time Slot Tracker: High-Fidelity Data Extraction Tool

Unlock hidden workforce insights with real-time data synchronization. I developed a production-ready Chrome Extension (Manifest V3) that extracts deep-level job slot metrics from Amazon's hiring portals. To overcome the industry-standard "401 Unauthorized" and CORS barriers, I implemented a "Main World" script injection technique, allowing the extension to securely leverage the site’s own session context.

The tool features a high-performance React-based glassmorphic dashboard that tracks 11+ critical metrics, including labor demand, filled positions, and batch availability.

AWS WAF & Amazon Captcha Auto-Recovery: Shadow DOM Smart Reloader - Stop losing leads to stuck captchas by Pasindu Piumal

AWS WAF & Amazon Captcha Auto-Recovery: Shadow DOM Smart Reloader

Stop losing leads to stuck captchas. I engineered "NopeCHA Smart Reload," a specialized Manifest V3 extension that solves the "infinite loop" problem in automated browsing. Unlike standard scripts, this tool utilizes a Deep Scan Architecture to penetrate Shadow DOMs—detecting failure signals in AWS WAF and Amazon Captchas that other tools miss.

Built with a high-performance React/Tailwind frontend, it features intelligent recovery logic that monitors solver health in real-time. When a failure is detected, it triggers a surgical 3-second recovery countdown and page refresh.
