Current Status What We Already Have: · Functional proof-of-concept automation script · Core automation logic for interacting with the web portal · Basic session management · Basic error handling · Multi-profile structure for managing multiple sessions Key Technical Challenges 1. Unreliable Form Submission The script is unable to reliably execute the final form submission step after identifying the required data. This prevents the automation from completing its workflow. 2. Session Stability & IP Rotation We are experiencing issues maintaining stable sessions when rotating IP addresses. The system triggers security blocks, making it difficult to maintain long-running sessions without interruption. This affects our ability to run multiple concurrent profiles. 3. Security Verification Handling The portal frequently presents security verification challenges that interrupt the automation flow. We need a solution that can automatically detect and handle these challenges without manual intervention. Technical Requirements We need help building a stable, production-ready system that addresses the following: 1. Reliable Form Submission · Debug and fix the submission logic to execute consistently and reliably · Implement proper error handling for the submission step · Ensure the workflow works across different scenarios 2. Stable Session Management · Implement reliable session stability without triggering security blocks · Maintain session consistency for the duration of each workflow · Handle connection failures gracefully with automatic recovery · Support residential or mobile proxies with session persistence 3. Security Verification Handling · Automatically detect security verification challenges · Handle challenges without manual intervention · Maintain session continuity after challenge resolution · Minimize challenge frequency through consistent browser fingerprinting 4.

I have 8+ years of experience in web development and am familiar with modern web technologies, frameworks like Playwright and Python and other tools. You need a stable automation system for a secure web portal. I understand the main problems: the final form submission fails, sessions break when IPs rotate, security checks interrupt the workflow, and multiple profiles must stay isolated. My approach is to use Playwright with persistent browser profiles, consistent fingerprints, and sticky residential proxies. The solution will include automatic detection and handling of security verification, retry logic for form submission, and asyncio to run 5–10 profiles safely. I can start right away.

Hi, I can help improve your internal web portal automation, but I cannot build systems that bypass security checks, defeat verification challenges, or evade portal protections using anti-detect methods or proxy rotation. What I can offer is a stable, compliant automation enhancement focused on permitted workflows, reliable form submission, session recovery, logging, and maintainable code. My approach will be to first review your existing script, portal permissions, session flow, form submission issue, and allowed automation boundaries. Then I’ll fix reliability problems without bypassing security controls. I can help with: * Playwright/Selenium debugging * Reliable form submission * Session timeout handling * Error detection and retry logic * Multi-profile workflow organization * Connection failure recovery * Logging and status tracking * Clean Python/Node.js code * Setup and troubleshooting documentation Deliverables: * Improved automation script * Fixed submission flow * Safer session handling * Error recovery logic * Activity logs * README and configuration guide * Troubleshooting notes I’ll focus on a stable, authorized automation workflow that respects portal security rules and avoids bypassing CAPTCHA, MFA, anti-bot checks, or access controls. Best regards Ankit

Unreliable form submission and session instability with IP rotation are preventing the automation from completing the workflow reliably. I will refactor the existing script to add robust wait and verification logic for the final form step, ensuring the submit action is confirmed before proceeding. I will integrate a resilient session manager that tracks cookies, handles re‑authentication, and synchronizes IP changes through a proxy pool without triggering security blocks. Detailed error handling and retry mechanisms will be built to keep each browser instance alive for long‑running tasks. Comprehensive documentation and a test suite will be delivered to verify stability across multiple concurrent profiles. Does the current proxy solution support authenticated proxies or should I implement a custom rotation service? Let’s chat, lock in the exact scope, and get started.

Greetings!! We have experience developing Python/Node.js browser automation systems using Playwright, Selenium and Puppeteer, including multi-profile workflows, persistent sessions, error recovery and detailed documentation. We can review your existing POC and focus on making the automation stable, maintainable and production-ready—especially the form-submission workflow, session lifecycle, concurrency, logging and recovery mechanisms. For secure verification challenges, we can implement reliable detection, pause/resume and compliant recovery flows rather than attempting to bypass or defeat the portal’s security controls. We can also isolate 5–10 concurrent profiles and ensure failures in one session do not affect others. Proposed stack: Python + Playwright + asyncio, persistent browser profiles, structured logging and configurable session management. We’ll provide the source code, setup/configuration guide, troubleshooting documentation and dependency list, with regular progress updates. Relevant automation work and technical details can be shared upon request. Warm Regards, Deepika Sharma

Hi! My name is Vandini, and I’m an experienced Python/JavaScript developer with hands-on experience in browser automation, Playwright, Selenium, session management, and multi-profile workflows. I can review your existing proof-of-concept, identify the cause of the unreliable form submission, and improve the automation architecture for stable long-running execution. I can also implement isolated browser profiles, persistent sessions, concurrency management, connection recovery, logging, and robust error handling for 5–10 parallel workflows. For security verification, I can implement reliable challenge detection and pause/recovery flows that preserve session state, but I would not bypass CAPTCHA, MFA, bot-detection systems, or other security controls through stealth or anti-detection techniques. The automation can instead be designed to work within the portal’s permitted workflow and recover safely when verification is required. I’d primarily use Python + Playwright with asyncio, persistent browser contexts, structured logging, retry/recovery mechanisms, and a clean profile-management architecture. I’ll provide the updated source code, setup/configuration guide, troubleshooting documentation, dependency list, and a stable production-ready workflow. I’d be happy to review the existing POC and target workflow so we can identify the root causes, define milestones, and provide a realistic timeline. I can start right away.

The form submission drops out when the page reloads after a hidden token expires. I’ll add a wait for the token element and retrigger the click using Playwright’s force option. For IP rotation I’ll bind each profile to a persistent user-data directory and verify the proxy handshake before each request. A common pitfall is relying on default Selenium timeouts, which let security challenges slip through before the script can react. I’ll replace generic waits with explicit checks for captcha frames and use Camoufox’s fingerprint lock to keep the browser profile consistent. Ready to start immediately and get the automation stable.

Anti-detect browser automation only fails in three places: form timing, fingerprint drift, challenge handling. Everything else is glue. Your PoC handles the happy path. Real work is keeping ten browser instances alive for hours against active fingerprinting. Relevant experience: - Built multi-worker crypto monitoring using n8n with CoinGecko polling, Sheets persistence, per-worker Telegram alerts. Workflow docs on request. Scheduling pattern carries over, browser-side fingerprinting is new territory. What this covers: - Form submission: explicit waits on response state, retries with backoff, verify-before-mark-success - Session + proxy: sticky residential per profile, rotation triggered by challenge events - Fingerprint: Camoufox or Rebrowser with persistent user-data-dir, randomized canvas/audio/WebGL - Multi-profile isolation: asyncio pool, separate browser contexts, no shared storage Phase 1: Audit PoC, map where detection triggers Phase 2: Rebuild session layer with anti-detect stack Phase 3: Challenge detection and recovery logic Phase 4: Stress test 10 concurrent profiles, write setup docs INR 12,500-37,500 is tight for full hardening. Can phase it: critical fixes in the lower band, full hardening as a follow-on milestone. Open to a PoC audit first so the split reflects what actually needs fixing. Best regards, Mohammad Juned
