I am looking for an experienced developer (Python, web scraping, anti-bot bypass) to finish and stabilize an existing scraping project. Repository: [login to view URL] The project is mostly complete, but it is currently not production-stable. Current state / problems: Scraper targets Allegro Allegro actively blocks scraping (blocked already on page 1, blocks after a few requests) Local execution (Selenium) works better than on a server On a VPS, the scraper gets blocked very quickly HTTP scraper (httpx) appears too static from Allegro’s perspective Browser fingerprint is almost constant Proxies are rotating residential proxies, but fingerprint and headers are not The project has mainly been tested locally, but must work reliably on a VPS (not local IP) What needs to be done: Implement and improve fingerprint rotation (UA, headers, window size, language, etc.) Introduce realistic randomness in behavior without changing the core scraper logic Adapt the scraper for high-volume request execution Focus on stability when running on a VPS No captcha solving - blocking is handled via fingerprinting + proxy rotation Do NOT change the business logic or architecture, only anti-bot hardening Requirements: Strong experience with web scraping and anti-bot systems Solid Python skills Experience with Selenium and HTTP-based scraping Understanding of browser fingerprinting Hands-on experience with residential proxies Ability to work with an existing codebase Budget: $150 USD Faster and stable delivery = higher bonus Looking for someone who can deliver results, not experiment for weeks If you have relevant experience, send a short description and preferably links to similar projects or case studies.

Hello, I’ve carefully analyzed your requirements and previously stabilized Python scraping systems targeting heavily protected marketplaces, including environments where local execution worked but VPS deployments were blocked quickly. In one similar project, I hardened an existing Selenium + HTTP scraper by improving fingerprint diversity and behavioral randomness without touching the core scraping logic, resulting in stable high-volume runs on a VPS using residential proxies. Your key issues—static browser fingerprints, insufficient header and environment rotation, and VPS instability—will be addressed by introducing controlled fingerprint rotation (UA, headers, viewport, language, timezone), realistic timing and interaction variance, and better alignment between proxy identity and browser signals. All changes will stay strictly within the anti-bot layer, preserving your current architecture and business logic. I’m available to start immediately and committed to delivering a stable, VPS-ready scraper quickly, focused on real-world results rather than long experimentation cycles. Best regards, Elenilson

⭐Hi, I’m ready to assist you right away!⭐ I believe I’d be a great fit for your project since I have extensive experience in web scraping, Python development, and anti-bot bypass techniques. My skills in implementing browser fingerprinting and utilizing residential proxies align perfectly with the requirements of your project. I have successfully tackled similar challenges in the past, optimizing scraper performance to bypass anti-bot measures and ensure stable operation on servers. Additionally, my expertise in Selenium and HTTP-based scraping will contribute to enhancing the fingerprint rotation and introducing realistic randomness to the behavior of the scraper. This project aims to address the pressing need for a stable and reliable scraping solution targeting Allegro while mitigating the challenges posed by blocking mechanisms and IP restrictions. By focusing on enhancing the scraper's stability on a VPS and fine-tuning the anti-bot measures, we can achieve seamless high-volume request execution without the need for captcha solving. If you have any questions, would like to discuss the project in more detail, or would like to know how I can help, we can schedule a meeting. Thank you. Maxim

Hi, I specialize in hardening existing scrapers against modern anti-bot systems—especially marketplace targets like Allegro where fingerprinting matters more than request volume. I’ve worked on multiple VPS-deployed scrapers where local Selenium “works” but fails remotely due to static fingerprints, headers, and behavioral signals. Based on your repo and description, the blocks you’re seeing are fingerprint consistency issues, not proxy quality. Rotating IPs without rotating browser and network signals will always fail on Allegro. My diagnosis (high level) Static browser fingerprint (UA, headers, viewport, languages) Deterministic Selenium behavior (timing, actions) HTTP scraper lacks realistic TLS/header diversity VPS environment exposes bot-like signals faster than local What I’ll do (without changing business logic) Implement full fingerprint rotation (UA, headers, viewport, timezone, locale, platform) Add human-like behavioral randomness (timing, navigation patterns) Align proxy rotation with fingerprint/session lifecycle Stabilize Selenium + HTTP modes for VPS execution Keep architecture intact—anti-bot hardening only Ensure scraper survives high-volume runs without page-1 blocking What I won’t do No captcha solvers No architecture rewrites No weeks of experimentation Deliverables Production-stable scraper on VPS Fingerprint + proxy rotation working together Clear notes on what was changed and why I’m ready to start immediately.

Hi — I can stabilize your Allegro scraper and harden it against bot blocking on a VPS without changing your core business logic. I’ve worked extensively with Python scraping, Selenium, and anti-bot bypass techniques, including fingerprint rotation, realistic behavior simulation, and proxy management. I understand how Allegro detects scraping (static headers, constant fingerprints, predictable timing, server-side bot detection) and how to harden a scraper for production. What I will deliver: Fingerprint rotation (UA, headers, viewport, language, timezone, WebRTC, canvas/audio entropy, etc.) Realistic randomness (mouse movement, scrolling, delays, request timing, viewport changes) while keeping your existing flow unchanged VPS-ready stability (better proxy handling, retry/backoff strategy, stealth Selenium configuration, anti-detection measures) HTTPX hardening (dynamic headers, rotating fingerprints, per-request variability) High-volume readiness with stable execution and minimal blocking No captcha solving, only fingerprint + proxy strategy as requested I will work directly in your existing repo, keep the architecture untouched, and deliver a production-stable version fast. I can start immediately and aim to complete this within 2–3 days. If you want, I can also provide a short report of the changes and recommended proxy/provider settings. Ready to begin.

The issue is not just the IP/Proxy. Allegro detects: The HTTP Client (httpx): Standard httpx sends a python-specific TLS handshake (JA3 fingerprint). I will fix this by wrapping the requests to impersonate a real Chrome browser handshake. The VPS Environment (Selenium): Running headless on a VPS leaks specific flags (like distinct WebGL rendering and font metrics). Simply rotating User-Agents is not enough. MY PLAN TO STABILIZE IT: Hardening: I will patch the Selenium instance (using undetected-chromedriver or specific stealth injections) to mask the "webdriver" property and normalize the fingerprint. Randomization: I will implement realistic mouse movement simulation and viewport resizing logic. Headers: I will align the header order and values to match the specific browser version we are mimicking. I respect the constraint: I will strictly modify the scraping driver/session setup, leaving your business logic and architecture untouched. I can start immediately. Best regards,

★★★ Python Web Scraping & Anti-Bot Hardening Specialist ★★★ Hi there, I can step into your existing Allegro scraper and make it production-stable on a VPS without touching your business logic or overall architecture. I have hands-on experience dealing with aggressive anti-bot systems, fingerprinting, and residential proxy environments, including cases where local Selenium runs fine but VPS traffic gets blocked almost immediately. I’ll focus on rotating and randomising browser fingerprints (UA, headers, viewport, language, timing patterns), adding realistic behavioural variance, and aligning Selenium and HTTP traffic so requests no longer look static or machine-generated. The goal is stable, high-volume execution under VPS conditions, not experimentation. I’m comfortable working inside existing Python codebases, strengthening anti-bot defences, and delivering fast, measurable results. I understand this is a results-driven task with a tight budget and timeline, and I can prioritise stability and reliability from day one.
