Eket, Nigeria - 9:07 pm local time
My hands-on experience includes transcribing and verifying election results data from public portals into structured Excel workbooks across multiple Nigerian states, flagging data quality issues along the way, and managing a 100+ record volunteer database with consistent, clean formatting. I'm also building practical SQL skills (SELECT, JOIN, GROUP BY, and more) to support data analysis work beyond spreadsheets.
I bring strong attention to detail, reliability, and a genuine interest in turning messy raw data into clean, accurate, and usable information. I'm currently seeking data entry, data cleaning, and data analysis projects where I can apply these skills and continue growing as a data professional.
