Key Skills

Freelancer Overview

I am a detail-oriented data annotation specialist with extensive experience in manual data labeling, company profiling, and OSINT research. My background includes verifying and correcting structured company attributes—such as jurisdiction, leadership, ownership, revenue range, and payment methods—using open-source materials like corporate registries, company websites, and press sources. I excel at resolving conflicting information through multi-source cross-checking and delivering clean, audit-ready datasets for downstream use. Skilled in Excel and Google Sheets, I consistently maintain high accuracy across large, repetitive datasets and thrive in remote, independent work environments. My academic research focused on information verification and data quality, and I am committed to upholding rigorous documentation standards and logic-driven annotation practices in every project I take on.
