About

Who I Am

I’m Richard Feng, a freelance web automation expert with 12+ years of coding experience. I specialize in web scraping, data extraction, and API reverse engineering — turning complex, protected websites into clean, structured data.

My toolkit spans Node.js (TypeScript), Python, Golang, and Java, with deep expertise in frameworks like Crawlee, Playwright, and Cheerio. I’ve built production systems that handle millions of requests with >99% success rates.

What I Do

I build and maintain 15 production-grade Apify actors serving over 3,100 users with a consistent >99% run success rate. The public-data actors need no API key and ship structured, RAG-ready JSON. My work spans four areas:

E-Commerce & Retail Data

Scrapers for major beauty and fashion platforms including Sephora (21 global storefronts), Ulta Beauty, Farfetch, Lululemon, Boohoo, and a universal Shopify scraper that works with any Shopify-powered store.

Public, Financial & Legal Data

Official U.S. datasets as clean, RAG-ready JSON — SEC EDGAR filings & XBRL financials, USAspending.gov federal awards, CourtListener court opinions, and ClinicalTrials.gov studies.

Social & Media Intelligence

Bluesky posts, profiles, and interactions via the AT Protocol, plus a YouTube subtitle & transcript scraper that outputs JSON, SRT, VTT, or LLM-ready text in 100+ languages.

Developer Utilities

Tools beyond scraping — SEO & structured-data auditing, web-to-PDF/image conversion, and high-performance load testing.

Specialties

• Reverse engineering private APIs — turning undocumented endpoints into reliable data sources
• Anti-bot bypass — Cloudflare, Datadome, Akamai WAF, and custom protections
• Multi-region scraping — handling different locales, currencies, and compliance requirements
• High-reliability systems — building scrapers that maintain >99% success rates at scale
