I build enterprise data infrastructure for companies where external data directly supports products, operations and business decisions - from complex websites and APIs to marketplaces, travel platforms, PDFs and scanned documents. ⭐ Top Rated Plus Developer · 150+ Projects Delivered · $500K+ Total Earnings · 14,100+ Hours Delivered My focus is not one-off scraping. I build production-grade data systems designed for scale, reliability and long-term operation - with validation, monitoring, error recovery and structured delivery. WHAT I DELIVER Enterprise Web Scraping & Data Extraction Complex, login-protected and JavaScript-heavy sources, marketplaces, APIs and high-volume extraction using Python, Playwright, Scrapy and Apify. Historical & Bulk Data Multi-year and large-scale datasets with completeness checks, reconciliation, deduplication and clear visibility into missing data. Travel & Booking Automation Hotel and airline pricing, availability and inventory, plus automated reservation and purchasing workflows with validation, retries and human review for high-risk actions. Document AI & OCR Invoices, contracts, statements and scanned documents processed at scale with structured extraction and confidence-based human review. Data Engineering & Enrichment ETL/ELT, normalization, entity matching and enrichment across APIs, CRM/ERP systems, PostgreSQL, Snowflake, BigQuery and internal platforms. HOW I WORK Validate → Architect → Scale → Monitor I start with the business requirement and real data sources, validate the critical edge cases, then design for production scale. Monitoring, quality controls and recovery are built into the system from the beginning. Data is delivered directly into your API, database, warehouse, S3, BI platform or internal application. For larger engagements, I can bring in specialists across data engineering, AI/ML, cloud and custom software from the wider engineering team.
