Curious by nature.
Careful by practice.

I’m John Eja, a collectibles writer with a statistics background. I help businesses explain products and markets, and research teams collect, check and report field data.

My Cardlines articles are published under John Bassey. My writing spans product guides, buying decisions, market analysis and collector education, with about six years of experience in the niche.

I build and modify Survey123/XLSForms and support the technical and data work behind field surveys. My contribution includes testing and validation, sampling and assignments, duplicate and GPS checks, data cleaning, analysis, mapping, and reporting.

My development-sector experience includes work through teams implementing survey programmes supported by international partners, including WHO, UNFPA and the World Bank. The work involved agreed methodologies, confidentiality, data quality and reporting.

I work independently and with my seven-person team when a project needs broader support. I can personally handle a defined writing, form or data assignment.

My freelance writing, including ongoing Cardlines contributions, has involved remote collaboration, client briefs, deadlines, revisions and email communication. For each project, we agree the scope, fee and deadline before work begins.
