I will build a python web scraper for javascript heavy and protected sites
Full Stack Web Developer
About this Gig
Anyone can write a script that works once on their laptop. You are here because the site fought back.
I take the scrapes that break: content that only exists after JavaScript runs, pages behind a challenge, endpoints that start returning 403 halfway through a run.
WHAT I HANDLE
JavaScript-rendered sites through a real headless browser when the HTML alone has nothing in it.
Sites that block naive scripts: proper delays, rotated headers, proxy support built in from the start.
Pagination, filters, category trees, and detail pages for the fields that only live there.
Output in the shape you use: CSV, Excel, Google Sheets, JSON, PostgreSQL, or your API.
SCRAPERS THAT SURVIVE PRODUCTION
The interesting failures come later: memory creeps until the process is killed, headless browsers pile up as zombies, a site adds a challenge and your check returns a happy 200 on a dead page. I build against them: retries with backoff, restart on crash, log rotation, Telegram alerts, and checks that verify content not status codes.
I do not touch logins you do not own or paywalled content.

FAQ
The site blocks bots. Can you still do it?
Often yes, with proper delays, rotated headers, a real browser where needed and proxy support built in. But I check the target before you order and tell you if it is not realistic. I will not take the money and then discover it cannot be done.
Will it keep working if the site changes?
Scrapers break when the target changes its markup; that is true of every scraper ever written. I keep the selectors in one place so a fix is quick, and on Premium you get an alert when a run returns nothing instead of silently collecting empty rows.
Is scraping legal?
Public data collected at a reasonable rate generally is, but it depends on the site terms and your jurisdiction, and I am a developer not your lawyer. I will not scrape behind logins that are not yours or harvest personal data against a site's terms.
