Web Scraping, Crawling & Data Extraction Done RightMarc Brown
Need structured data you can actually use without brittle scripts or legal headaches?
I build reliable, compliance-aware scrapers that extract, clean, and deliver data in the exact format your team needs.
From product catalogs and pricing to real-estate listings and lead data, I focus on accuracy, scale, and maintainability so your pipeline keeps running.
What's included
Deliverable 1: Discovery & Data Map
We define targets, fields, frequency, volume, and delivery format. I create a clear data spec (schema + sample rows) before a single request is sent.
Deliverable 2: Robust Scraper/Crawler Build
Production-grade scraper using Python + Playwright/Selenium/Requests with smart retries, backoff, session management, and anti-bot strategies (rotating proxies, headless browsers, request fingerprinting).
Deliverable 3: Data Cleaning & Normalization
Deduping, field validation, type casting, currency/units normalization, and light enrichment (e.g., geocoding, category mapping) so data is analysis-ready.
Deliverable 4: Exports & Delivery
Delivery as CSV/JSON/Parquet, pushed to S3/Google Drive/FTP/Email or a database (PostgreSQL/MySQL). Includes sample dashboard/notebook if helpful.
Deliverable 5: Scheduling, Logs & Monitoring
Automated runs (cron/GitHub Actions/Airflow), run logs, alerting on failures, and simple status reports so you can trust the pipeline.
Optional Add-ons
- Headless browser captcha solving (where permitted) and residential proxy setup
- API fallback/augmentation when a first-party endpoint exists
- Lightweight admin dashboard to view last run, counts, and download files
- ETL to your warehouse (BigQuery/Redshift/Snowflake)
- Ongoing maintenance SLA (site changes, selector drift, proxy rotation)
FAQs
I operate compliance-first. We review robots.txt, site Terms of Service, and your intended use. I avoid protected content, rate-limit responsibly, and prefer official APIs when available. You confirm you have the right to collect/use the data.
Python stack (Playwright, Selenium, Requests/HTTPX, BeautifulSoup/Parsel, Pandas), plus rotating proxies and queueing where needed.
Polite crawling, randomized headers, proxy pools, backoff, and (only if permitted) captcha solving. Stability first, not aggression.
Yes scheduled jobs with monitoring and alerts. I also offer a maintenance plan to handle site changes.
CSV/JSON/Parquet, or direct to DB/warehouse. I include a data dictionary and a few sample queries.
Sure normalize categories, geocode addresses, match SKUs, or join with public APIs where allowed.
A focused single-site scraper typically 2–5 days (including spec + pilot run). Larger multi-site projects vary by scope.
