I extract data from any website and deliver it clean, structured, and ready to use. What I do best: • Web scraping (any size: 100 records to 10 million rows) • Login-protected and JS-heavy sites (I work with credentials you provide — never bypass auth) • API integration and automation (REST, GraphQL, Webhook) • Data cleaning, normalization, and dedup • Output in any format: CSV, Excel, Google Sheets, JSON, direct to your database How I work: You tell me the data you need. I deliver a working sample on 1-2 sites first so you can verify quality before committing. Then I scale to the full scope, on the schedule you set (one-time, daily, weekly). Each delivery is source-cited, deduped, and ready to plug into your workflow. Tools I use daily: Python, requests, Playwright, Selenium, BeautifulSoup, Scrapy, Pandas, SQL, and AI-assisted parsing for tricky HTML. For login-protected sources, I work with credentials you provide — a temp account, read-only API key, or a logged-in session. Typical projects: • E-commerce price/product monitoring across competitors • Real estate listing aggregators (Zillow-style feeds, rental sites, MLS data) • Lead generation lists from directories, Google Maps, LinkedIn • Market research datasets with citations • Routine extraction of reports, dashboards, or financials from client portals • API-to-API or API-to-spreadsheet automation For login-protected or paywalled sites: I work with credentials your team provides. I do not bypass authentication — I use access you give me. I focus on outcomes, not toolchain. You get the data you asked for, in the format you asked for, on the schedule you set — and I keep the build process out of your way. Reply with: (1) the data you need, (2) the source sites, (3) how often it should refresh. I'll send back scope + quote within 24 hours.

I build custom Python scrapers, automated data extraction tools, and clean research lists for clients who need data from websites that aren't easy to pull from. Every project is delivered as a polished CSV, Excel, or Google Sheet — ready to use from day one. 🐍 Custom Python Scrapers When a website has data you need but no easy way to get it, I write a custom scraper to pull it for you. This includes sites that block simple tools, sites that need search forms filled out, sites with thousands of pages to work through, or sites that need to be checked on a schedule. You get the finished data — cleaned, organized, and delivered in the format you want. 🔍 Data Extraction & Research I extract structured data from public sources: government datasets, business directories, company websites, industry association sites, public registries, court and permit records, Google Maps, and event or conference pages. I pull what you need, verify it against the original source, and hand it off in a clean file. 🎯 Targeted Contact & Business Lists I build targeted lists by industry and geography. If you need every business of a specific type within a state, region, or country, this is one of my most common projects.. I've built lists ranging from a few hundred contacts to several thousand, across service trades, hospitality, and niche B2B verticals. You tell me who you want to reach, and I deliver a clean, ready-to-use contact file. 🔧 How I Work I explain my approach in plain English before I start. You'll get a sample of the first batch for approval so you can confirm the format and quality match what you need. The full delivery follows once the sample is approved — no surprises, no rework. 💼 About Me Based in the United States (Virginia). Every project is handled personally — no subcontracting, no outsourcing, no agency layer. 100% Job Success Score, Top Rated status maintained on Upwork.
