Freelancer Overview

I am a detail-oriented data annotation specialist with hands-on experience in manual company profiling, legal-entity verification, and structured data validation using open-source intelligence (OSINT). My work involves verifying and correcting key company attributes—such as jurisdiction, directors, shareholders, revenue range, and payment types—by cross-referencing official registries, company websites, LinkedIn, and press sources. I excel at managing text-first datasets that require logical evaluation and manual verification without automation tools, ensuring high accuracy and consistency in every project. My expertise includes advanced Excel-based annotation workflows, structured data formatting, and meticulous quality checks to detect and correct inconsistencies. I am highly analytical, detail-focused, and comfortable working independently on large, ongoing remote projects. My strong research skills and ability to interpret complex business and legal documents enable me to deliver reliable, high-quality training data for AI and data-driven applications.
