I specialise in large-scale web research and structured data collection, helping founders, teams, and growing companies build accurate, reliable datasets they can actually use.
As a Web Research & Data Collection Specialist, I’ve delivered projects across industries including tech, aviation, culture, and consumer markets. My work involves researching, verifying, and compiling 1,000–2000+ records per project, covering business listings, contact databases, lead generation, competitor profiling, audience segmentation, and influencer identification. I focus on clean structure, consistency, and accuracy, not just filling rows.
I don’t just gather data. I ensure it’s validated, organised, and decision-ready.
Beyond research, I bring experience as a Startup Generalist and Product Operations Coordinator. I’ve supported founders, managed interns, and set up internal systems and documentation that help early-stage teams operate with clarity. That said, my primary focus here is delivering high-quality research and data at scale.
What I bring to the table:
-Web research & data collection
-Business listings, directory building & contact research
-Lead generation & data verification
-Market & competitor research (B2B/B2C)
-Survey design & insight reporting
-Product operations & MVP tracking
-Tool setup: Google Workspace, Notion, Trello, GitHub
-Internal documentation & process creation
-Founder support & operational coordination
I’m adaptable, precise, and very particular about clean, useful data. If you need someone who can take an unstructured brief and turn it into a clear, reliable dataset, I can help you move things forward efficiently.
