Need structured data extracted from the web, fast and clean? You're in the right place. Web scraping and data collection are my core specialty. I build targeted scrapers in Python using BeautifulSoup, Requests, and Selenium, handling pagination, anti-bot measures, dynamic content, and geocoding. Deliverables land in Excel, CSV, or JSON, clean and ready to use from the first row. By day I'm a Data Analyst at ABN AMRO Bank in the Netherlands, where precision and reliability aren't optional. I bring that same standard to every project. What I deliver: ✔ Web Scraping & Data Collection: websites, directories, marketplaces, portals, and APIs scraped at scale. Pagination, login walls, and JS-rendered pages handled. Output in your preferred format. ✔ Excel Automation & Reporting: advanced formulas, pivot tables, dynamic dashboards, and VBA/macro automation. Messy spreadsheets turned into decision-ready reports. ✔ Data Analysis & Dashboarding: trends and patterns surfaced using Excel, SQL, Python, Power BI, and Tableau. ✔ Data Cleaning & Quality Control: deduplication, normalization, formatting, and validation. Fast and detail-oriented. ✔ NL-Specific Tasks (Netherlands): based in the Netherlands, I also take on Dutch-language and local-market work: photo categorization and visual data tasks, market research and mystery shopping, localization and UX testing, and voice/audio tasks in Dutch. Past projects: scraped 4,400+ records with geocoding from live websites; built multi-source restaurant databases with interactive dashboards.
