I'm Mavis — a freelance data & financial analyst. Businesses, finance teams, institutions and individual professionals send me the numbers they can't read; I send back a clear picture of what's working, what's costing money, and what to do about it first. Plain English, no jargon. Excel, Power BI, SQL and Python do the work in the background — you only ever see the decision.

I trained through ALX Africa's Data Science programme and a professional data analytics certificate, then went straight into applied work as a Data Science & Analytics intern — every task a real company question answered with a real dataset.
I'm now studying towards the ACCA (Chartered Certified Accountant) qualification, which is deliberate: it means I read your numbers the way your accountant and your auditor read them, not just the way a data tool does. Analytics on one side, accounting discipline on the other.
Every project ends the same way — a plain-English page that says here's what's happening, here's why, here's what I'd do about it. No chart dump, no jargon, no homework left for you.
View my services →Financial reporting, audit and assurance — the accounting side of the numbers, alongside the analytics.
Dashboards, sales & profitability analysis and reporting clean-ups for small and medium businesses — remote, worldwide.
Sales performance, RFM segmentation and conversion-funnel projects delivered as dashboards with written recommendations.
Data modelling, warehousing and database administration.
Python, SQL and statistics applied to African business datasets.
You have invoices, till slips, a bank feed and three versions of the same spreadsheet — but no straight answer to simple questions.
By the time the numbers are compiled by hand, the month is gone and the decision was already made on instinct.
Strong top-line sales often carry loss-making lines underneath. Nobody sees it until year-end.
Totals typed over formulas, duplicate codes, subtotals inside the data. Clean structure saves you money.
A free 30-minute data review — sales, stock or expenses. No cost, no obligation, no sales pitch. Just what your numbers are already telling you.
Book the free reviewEach one is a fixed-price project with a defined deliverable and a date. You know the price and the outcome before I start.
Product, category, channel and region performance with margin attached to every line — so you can see which best-seller is quietly costing you money and which slow-mover is carrying your profit.
Revenue, gross margin, expenses, cash position and budget-versus-actual — modelled once, refreshed on demand. The reporting a board, a bank or a buyer will accept without arguing.
Not every customer is worth the same. RFM segmentation, churn risk, lifetime value and basket analysis tell you who to protect, who to win back, and what to sell them next.
Before analysis comes trustworthy data. I restructure the workbooks businesses grow into — hardcoded totals, duplicate codes, buried subtotals — into clean, auditable form, and put controls in so it stays that way.
Send one file. I tell you what your data can and can't answer today — and whether you even need me.
A short written proposal: the question, the deliverable, the timeline, the price. You approve before anything starts.
Cleaning, modelling, dashboard, findings — plus a walkthrough so your team owns it after I leave.
Most clients start with the free review and we decide together. Bring your messiest spreadsheet — I've seen worse.
