Hire the Best Scrapy Developers

If your team is manually logging into systems, copying data between platforms, or verifying records by hand — that process can be automated, and I build the bots that do it reliably, long-term. I'm a Python automation and backend engineer with 5+ years building production-grade RPA bots and data extraction pipelines, currently at a financial institution where accuracy and stability aren't optional — they're the whole job. WHAT I CAN HELP YOU WITH • Web scraping and structured data extraction • Web automation — logins, form submission, verification workflows, 2FA and CAPTCHA handling • Python RPA using Selenium and Playwright • Excel/CSV → database automation • API integration and backend automation (Flask, FastAPI) • LLM API integration — adding AI-powered extraction, classification, or summarization into your existing workflows • Bots built with logging, retries, and proper error handling — not scripts that break silently • Data visualization to support business decisions SELECTED EXPERIENCE • High-performance data extraction pipeline: Redesigned a document extraction system for a financial institution, cutting processing time for 1,000-page files from ~60 minutes to ~40 seconds — a ~90x speedup — while maintaining accuracy on high-stakes, compliance-sensitive data. • Browser automation for regulatory data collection: Built a Python/Playwright automation platform to pull credit bureau files from a government portal, replacing a manual process that consumed ~13 person-hours/day across two staff members with a single automated pipeline — freeing that time for higher-value work. • Large-scale web scraping platform: Built and deployed a statewide property data extraction system (2,700+ properties scraped and growing), running as a nightly automated job that checks for new listings and scrapes them without manual intervention. Includes an admin dashboard to monitor the pipeline and backend APIs powering web and Android apps used for real-world purchasing decisions. WHY CLIENTS WORK WITH ME • Clear communication and realistic estimates — no surprises mid-project • Clean, maintainable code other developers can pick up later • Built for edge cases, not just the happy path • Enterprise-level experience applied to projects of any size I treat every project as something I'll maintain, not just ship and disappear. Send me your workflow or automation idea — even if you're still evaluating options, I'll tell you honestly what's worth automating and what isn't.

I help businesses turn Frappe CRM into an AI-Enhanced CRM with AI Sales Automation that captures prospects, qualifies opportunities, enriches customer data, automates follow-ups, prioritizes high-intent buyers, and helps sales teams build predictable pipelines that close more business. My primary specialization is Frappe CRM. Unlike developers who only connect APIs, I build directly inside the Frappe ecosystem by developing custom apps, extending CRM functionality, creating custom DocTypes, integrating AI services, building messaging modules, and deploying self-hosted environments. Alongside Frappe CRM, I build AI Sales Automation using n8n, Zapier, Make, Python, OpenAI, Claude, and Gemini to automate sales operations, AI Sales Workflows, AI Sales Pipelines, and customer engagement.

I build web scrapers and data pipelines that actually stay alive in production — even on sites protected by Cloudflare, DataDome, and advanced bot detection. After 5+ years of solving the hardest scraping challenges, I know the #1 reason most scrapers fail: they get detected and blocked within hours or days. I fix that by making scrapers look and behave like real users while delivering clean, structured data on schedule. What I deliver: • Robust multi-site / multi-country scraping systems with reusable architecture • Advanced bypassing for Cloudflare, DataDome, PerimeterX, and similar protections • Reliable daily or real-time pipelines feeding Google Sheets, BigQuery, PostgreSQL, or your database • Fast fixes for broken or brittle scrapers (with proper error handling, monitoring, and change detection) Recent projects include: • Multi-country e-commerce price and product monitoring across Europe and Asia with automated Google Sheets output + long-term BigQuery storage • Shared checkout automation framework working across multiple retail sites • Complete rebuild of large-scale public records pipelines from fragile to production-grade My stack: Python, Playwright, Scrapy, BeautifulSoup, Docker, AWS, GCP, BigQuery, PostgreSQL Best fit for: • Scrapers that keep getting blocked or breaking • Complex, multi-site, or high-protection targets • Ongoing pipelines that must run unattended for weeks/months • Inherited scrapers that need to be stabilized and maintained If you have a specific site or pipeline that’s causing headaches, send me the details and I’ll tell you exactly how I’d approach it. Looking forward to helping you get reliable data without the constant maintenance hassle.

If your team is stuck doing manual work, buried in spreadsheets, or struggling to collect data from sites nobody else could figure out - I build the system that fixes that. I specialize in Python automation, large-scale web scraping, data pipelines, and AI integrations. I've delivered 100+ projects including extracting 10,000+ product records from Amazon and Kohls, building scrapers for Cloudflare-protected platforms, and developing AI-powered backend workflows that run 24/7 without babysitting. Here's what I can build for you: • Web scraping systems — Scrapy, Playwright, Selenium, BeautifulSoup. Handles dynamic JavaScript-heavy sites, login-gated pages, anti-bot detection, rate limiting, pagination, and proxies. If a site has data, I can get it. • Data pipelines — Full ETL pipelines that extract, clean, deduplicate, and deliver structured data into PostgreSQL, MongoDB, CSV, Excel, or directly into your app. • API integrations — Connect third-party services, build REST API backends with FastAPI, Flask, or Django, and wire up webhooks and automation triggers. • AI agent workflows — OpenAI API, Claude, LangChain, RAG pipelines, and vector databases. I build intelligent automations that replace repetitive decision-making, not just repetitive clicking. • Workflow automation — n8n, Make, Zapier, or custom Python. Automated pipelines that handle lead generation, data mining, data extraction, and reporting without manual input. I work on ongoing projects and one-time builds. My systems are production-ready, with retry logic, error handling, monitoring, and documentation - so they keep running long after I've delivered them. 100% Job Success Score | 5.0★ rating | Top Rated MY STACK Scraping: Python, Scrapy, Playwright, Selenium, BeautifulSoup, Puppeteer, Proxies, Anti-bot Bypass Backend & APIs: FastAPI, Flask, Django, REST APIs, Webhooks, JavaScript AI & LLM: OpenAI API, Claude, Gemini, LangChain, LlamaIndex, RAG, Vector Databases, AI Agents Automation: n8n, Make, Zapier, ETL Pipelines, Data Mining, Data Extraction, Lead Generation Databases: PostgreSQL, MongoDB, MySQL, SQLite, CSV, JSON, Excel Cloud: AWS, GCP, Docker, Kubernetes, Lambda, EC2, Cloud Run If this sounds like what you need, send me a message or shoot me an invitation, I'll jump on a quick call or send back a Loom video walking through how I'd approach your project.
