Are you losing track of your B2B leads in messy spreadsheets? Is your CRM outdated with wrong company emails, incorrect locations, or missing phone numbers? Or maybe you are spending hours manually copying and pasting information from competitor websites? Most growing businesses struggle with messy company (firmographic) and customer (demographic) data. I bridge that gap as your reliable data operations partner. I clean, extract, and update your business databases so your sales and marketing teams can work with 100% accurate information. You don't need to purchase complex software or learn how to code; you just need a dependable partner to keep your records spotless. 🛠️ How I help your business grow I offer three straightforward services designed to turn your data mess into a powerful, clean pipeline for your business: 1. 📊 CRM & Database Management (Company & Customer Profiles): Do you already use a CRM (HubSpot, Pipedrive, etc.), Airtable, or Google Sheets, but it’s a complete mess? I take your raw business information, organize it linearly, and upload it into your existing systems. I ensure your firmographic (industry, company size, revenue) and demographic data are always up-to-date and ready to use. 2. 🤖 Automated Web Scraping (Targeted Data Delivery): Need to extract product catalogs, local business directories, competitor prices, or B2B directories? You don't need to run or buy any code. Just give me the target URLs, and I will use my custom technology to extract the information and deliver a perfectly structured Excel or Google Sheet file. 3. 🔍 Manual Data Collection & Verification: For tasks where absolute precision is non-negotiable and automated tools or AI fail. I handle meticulous web research, manual data entry, and continuous updates in your spreadsheets with a strict eye for detail to ensure zero human errors in your lead lists. 🤝 My operational philosophy My clients appreciate that I combine a strong technical background (Python, SQL, and APIs) with a human, jargon-free communication style. I don't sell you code or complex promises; I sell you clean data, accurate target lists, and peace of mind. I adapt quickly to your existing workflow and implement rigorous quality controls. Whether you need a massive data extraction or a dedicated human eye to verify your accounts, I deliver accurate results on time, every time. 💬 What clients say ""He took our messy, unorganized leads and perfectly updated our systems.
