"I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it." - Bill Gates I am that person who is always Lazying around, does that mean anything to you? Is it Crazy for me to say this? Well, no I'm not. I want to get your job done as quickly as possible, but I also want to make sure it's done right the first time. I would rather finish my job and be able to relax than have to do it over again. Who am I, you might be asking? I am a Python, SQL, HTML, and PHP developer and an all-around nice guy. I have built systems that can scrape emails and phone numbers from the entire web. I can scrape Amazon and eBay, and everyone knows how hard it is to scrape Amazon. I have also built drop shipping systems, websites and CRM systems. I automated my position out of my job. It got so bad that I would show up to work and sit there with nothing to do. But Simon, if you're that good, why are you here? I am here to challenge myself. I want to take on new tasks and improve my skills. I want to increase my knowledge and the only way I can do that is by working with wonderful people like you. So what are you waiting for? Drop me a message and you won't be disappointed.
A Web Crawling Developer builds automated programs that systematically browse websites, extract structured data, and deliver it in usable formats for analysis, monitoring, or integration into business systems. Hiring a skilled web crawling developer turns scattered online information into reliable datasets that power pricing intelligence, market research, lead generation, SEO audits, and machine learning pipelines.
A web crawling developer designs, builds, and maintains crawlers and scrapers that navigate websites at scale. Crawlers discover and traverse URLs across domains, while scrapers parse the underlying HTML, JSON, or rendered DOM to pull specific fields. The developer handles the full data pipeline, from request scheduling and proxy rotation to data cleaning, deduplication, and storage.
The commercial value is direct. Clean, structured web data feeds price monitoring dashboards, competitor tracking, sentiment analysis, real estate listings, job aggregators, e-commerce catalogs, and research datasets. A capable web scraping developer makes the difference between a fragile script that breaks weekly and a production-grade crawler that runs unattended for months.
Engagements with a freelance web crawling developer typically produce one or more of the following:
Strong candidates show fluency across the standard scraping stack. Look for direct experience with:
Adjacent skills that often appear on the same profile include data engineering, ETL pipeline development, API integration, Python backend development, and machine learning data preparation.
Web data extraction is used across nearly every digital sector. The most common use cases include:
The right hire combines coding skill with practical experience handling real-world scraping obstacles. Strong signals to look for include:
Useful interview questions to copy and use:
Freelancer.com gives you access to a global pool of web scraping experts, data extraction engineers, and Python developers with proven crawler-building experience. You can review portfolios, completed project counts, client reviews, and verified skill tests before you shortlist. Clients set their own budgets and receive competitive bids, so you control scope and cost while comparing approaches from multiple developers in parallel. Freelancer.com's Milestone Payments hold funds securely and release them only when you approve delivery, which protects both sides during multi-stage scraping builds.
Hiring the right web scraping developer comes down to a clear brief, careful bid review, and evidence-based final selection. The steps below walk through how to source, evaluate, and award a web crawling project on Freelancer.com so you end up with a reliable crawler and clean data, not a brittle script.
The project brief is the single biggest determinant of bid quality, because it filters for developers whose experience genuinely matches your scraping use case. A vague brief attracts vague proposals; a precise brief attracts developers who can quote a realistic timeline and approach. Head to the
Bids are short proposals, not just price quotes. They reveal how each developer interprets your brief, what scraping approach they propose, and what they consider realistic for timeline and infrastructure. Read carefully and shortlist candidates whose understanding of the work matches your requirements.
The final decision combines proposal quality with profile evidence. Look beyond a single impressive sample and assess consistency across past scraping projects, because reliability matters more than flash for crawlers that need to run unattended.
A simple single-site scraper with clean HTML can be delivered in a few days. Multi-source crawlers, JavaScript-rendered targets, or pipelines with anti-bot handling and database integration typically take two to six weeks. Ongoing maintenance is common because target sites change their structure over time.
Scraping publicly available data is generally permissible, but legality depends on the target site's terms of service, the type of data, and applicable laws like GDPR or CCPA. A professional web crawling developer will respect robots.txt, avoid scraping personal or copyrighted content without permission, and advise on compliant approaches. Always confirm legal boundaries with your own counsel for sensitive use cases.
A crawler discovers and traverses URLs across one or many websites, mapping their structure. A scraper extracts specific data fields from individual pages. Most real projects combine both — a crawler finds pages worth visiting, and a scraper pulls the structured data from each one.
Yes. Experienced developers use headless browsers like Playwright or Puppeteer to render JavaScript, handle authenticated sessions, and interact with dynamic elements. These targets take longer to build for and require more careful maintenance than static HTML sites.
Both options are common. Some clients want delivery of the source code only, while others ask the developer to deploy the crawler on AWS, Google Cloud, or a managed service with scheduling and monitoring. Specify your preference in the brief so bids reflect the right scope.
