How to become a data analyst in Nigeria without a CS degree
The skills, tools and portfolio projects hiring managers in Lagos and Abuja look for — and a 12-week plan to get there on a budget.

Most entry-level data roles in Nigerian banks, telcos and FMCGs ask for the same three things: strong Excel, one visualisation tool and the ability to explain numbers to non-technical managers. A computer science degree is rarely on the list.
Weeks 1–4: Excel you can defend in an interview
Master lookups, pivot tables and charts using real datasets — sales by state, airtime top-ups, school results. Build one monthly report you can show.
Weeks 5–8: Power BI and storytelling
Turn your Excel report into an interactive dashboard. Practise a two-minute walkthrough: what changed, why, and what you would do next.
Weeks 9–12: Portfolio and applications
Publish three projects, add your Ilimexa verification link to your CV, and apply to analyst, reporting and MIS roles — not only jobs titled “data analyst”.
