I am looking for an experienced full-stack developer or Chrome extension specialist to build a custom browser tool designed to handle high-traffic web portals efficiently. The primary goal of this tool is to allow a user to manage multiple isolated browser sessions/profiles simultaneously, pre-fill form data across all of them, and execute rapid, automated data injection and button clicks with a single action to bypass slow-loading traffic spikes and secure multiple bookings across different accounts instantly. Key Requirements & Modules: Multi-Session Isolation: Ability to run and manage multiple independent browser profiles or tabs simultaneously without shared cookies or session conflicts. Master Profile & Auto-Fill: A centralized settings panel to store pre-filled form data (such as names, contact details, and identification numbers) and inject them instantly into target fields. Single-Click Batch Automation: A trigger mechanism that simultaneously injects data, checks required agreements, and simulates click events across multiple open form windows in a fraction of a second. Speed Optimization: Lightweight script architecture built to minimize latency during peak server traffic and high-demand windows. Deliverables: Fully functional Chrome Extension or desktop automation script source code. Clear instructions on how to set up multi-profile environments and operate the tool locally. Please share examples of similar multi-session automation tools or high-speed form fillers you have built, along with your estimated timeline and cost.

I can build a custom browser automation tool for handling high-traffic web portals. Your main purpose is to manage multiple isolated browser sessions/profiles simultaneously, allowing each session to maintain its own cookies, login state, and account information without conflicts. The tool will be lightweight and capable of operating efficiently when the target website is experiencing heavy traffic or slow response times. It will also include a key feature where the user can centrally save information such as names, contact details, and identification numbers and then it will instantly inject that data into the relevant fields across multiple open sessions. The tool will also support single-click batch automation, where one action can trigger data injection, check required agreements/checkboxes, and perform button-click actions across multiple browser windows or tabs as quickly as possible. The latency will be minimized so the automation can be fast and efficient as possible during high-demand booking periods. The final delivery be a fully functional desktop automation script, including the complete source code and clear setup instructions for creating and managing the multi-profile environment locally.

Most bids will promise a single Chrome extension running across multiple tabs, but on high-traffic booking portals, that approach fails immediately - standard tabs share cookies, storage, and IPs, triggering rate limits and session collisions the second you click submit. I'm an engineer based in Ohio. We build high-speed browser automation, automated bot systems, and stealth session-management tools all the time. We recently engineered a high-frequency automation suite that manages multiple isolated browser sessions in parallel, executing synchronized form fills and submissions without session bleed or lag. Here is how I’d structure your tool to actually beat the traffic: - True Session Isolation: Instead of a brittle extension, we’ll use Playwright with isolated browser contexts. Each session gets its own independent cookie jar, cache, and optional proxy binding—zero collision. - Sub-Millisecond Injection: We store your master profiles locally and inject the data straight into the DOM via low-level JavaScript runtime execution rather than slow, simulated typing. - Synchronized Trigger: A centralized dashboard where you hit one trigger to fire injections, check agreement boxes, and execute submit clicks across all profile windows concurrently in a fraction of a second. This is a focused 4–5 day build. Let's chat, review the target portal, and get your setup running!

I will build an isolated multi-session browser automation system where each profile maintains independent cookies, storage, authentication, and form state, while a master panel securely manages reusable form data. I will implement the autofill engine to detect target fields, map stored values to them, handle checkboxes/dropdowns, validate required fields, and inject data efficiently without unnecessary page operations. I will create a single-action automation workflow that coordinates all permitted open sessions, performs field injection and required UI interactions, and provides clear success/error status for each session. For high-traffic conditions, I will optimize the architecture for minimal DOM operations, event-driven execution, parallel session coordination, timeout handling, and graceful recovery when pages load slowly or elements appear asynchronously. A major challenge in this type of system is keeping sessions truly isolated while coordinating actions centrally. I will address this through separate browser contexts/profiles, strict state management, and per-session execution queues. I will deliver clean, maintainable JavaScript/Chrome Extension or desktop automation source code, configuration instructions, and a practical setup guide for multiple profiles.

Hello, I can build a lightweight browser automation tool/Chrome Extension for managing multiple isolated sessions and performing fast, synchronized form actions. The solution can include: • Independent browser profiles/sessions with isolated cookies and storage • A master settings panel for reusable form data • Automatic field detection and data injection • Batch actions for filling fields, handling required checkboxes, and triggering permitted click events • Lightweight JavaScript architecture focused on low latency • Clear local setup and usage documentation • Clean, maintainable source code with configurable target selectors I work with JavaScript, PHP, web development, APIs, and automation, and I can structure the extension so the core automation logic is modular and easy to adapt when the target portal changes. I would first review the target portal and its form behavior, then implement and test the multi-session workflow carefully rather than relying on fragile timing-based automation. Estimated timeline: 5–10 days depending on the number and complexity of target portals. I can provide the complete source code and setup documentation at delivery. Best regards, Muhammad Umair
