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 can help stabilize and harden your Allegro scraper for VPS execution, focusing on anti-bot measures without altering your existing business logic. I’ll implement dynamic fingerprint rotation—varying user agents, headers, window sizes, and languages—and introduce realistic randomized behavior to mimic human browsing. I have extensive experience with Selenium and HTTP scraping, residential proxies, and bypassing anti-bot protections, ensuring high-volume requests run reliably on a server. I will work directly with your current codebase to optimize stability, prevent rapid blocking, and maintain full compatibility with your workflow. I can deliver this promptly, with clear testing to confirm VPS stability, and provide examples of similar scraping projects I’ve successfully hardened in production. Regards, Zafar

I’m Muhammad Muneeb, a Python developer specializing in high‑resilience web scraping and anti‑bot hardening. I’ve reviewed your Allegro use case and understand the exact pain points: aggressive fingerprinting, VPS instability, static headers/UA, and the gap between local Selenium success and server-side blocking. I can stabilize your existing codebase without altering business logic or architecture, focusing purely on anti‑bot improvements. I’ll implement robust fingerprint rotation (UA, headers, locale, viewport, timezone, navigator hints), introduce human‑like randomness in timing and interactions, and align proxy + fingerprint coherence for residential IPs. I’ll also harden the HTTP/Selenium paths for high‑volume VPS execution, ensuring consistent behavior under load—no captcha solving, no experimental rewrites. I work quickly, cleanly, and professionally, with proven experience on blocked marketplaces. I can start immediately, deliver within budget ($150), and prioritize fast, stable results suitable for production.

As an experienced full-stack developer, my expertise extends to web scraping, providing me with powerful tools to tackle intricate projects like yours. Over the last eight years, I have gained hands-on experience with Python and web scraping libraries, notably Selenium and httpx. This places me in an excellent position to help stabilize your existing scraping project, making it production-stable, scuffing off Allegro's anti-bot blockade. My familiarity with browser fingerprinting and residential proxies empowers me to address one of the core challenges you've mentioned. I will not only actively improve fingerprint rotation for enhanced anonymity but also introduce realistic randomness within the bounds which won't interfere with the core scraper's logic. The skill set I possess is exactly what you are looking for as I encompass a comprehensive understanding of the anti-bot systems you need. Staying within your budget of $150 USD, I promise not just efficient delivery but a robust and reliable solution as well. Quality is a non-negotiable element in my work and that reflects in my client satisfaction rate. Let my track record speak: I am results-driven and ensure that my clients don't endure extended experimentation periods. Choose me for a faster turnaround that doesn't compromise on stability or capability."

I can help you stabilize and harden your existing Allegro scraper without touching the core business logic or architecture. I have strong hands-on experience with Python scraping, Selenium, httpx, browser fingerprint rotation, and working around anti-bot systems using realistic behavior and residential proxies on VPS environments. I will implement proper fingerprint and header rotation, add human-like randomness (timing, viewport, language, minor interactions), and adapt the scraper to run reliably under higher load on a server. I’ve worked on similar blocked-marketplace scrapers where local success didn’t translate to VPS stability and know how to close that gap. I can move fast, focus only on what matters for stability, and deliver within your budget, with clear improvements you can immediately verify.
