Most guides teach you tools.
This one teaches you the job.
One real business problem — a retailer's mysterious revenue drop — solved end-to-end in SQL, Excel, Power BI, and Python. Follow the 90-day plan, build the portfolio, get hired.
This is a toolkit, not an e-book
You don't just read about the analysis — every file to actually run it yourself is in the download.
-
The 90-day guide (14 parts + 4 appendices)The skill stack employers pay for, week-by-week roadmap, portfolio blueprint, a 15-question interview bank with model answers, verified certification info, and a curated free-resource directory.
-
Step-by-step Setup & Installation GuideEvery tool downloaded, installed, and verified before Week 1 — system requirements, download sizes for metered data, free alternatives to every paid tool, a no-install cloud path for low-spec laptops, and beginner troubleshooting. Never get stuck on "how do I even get the software."
-
A working Excel workbookSample data pre-loaded, live SUMIFS & XLOOKUP formulas — click any cell and see exactly how it's built. No pasted numbers.
-
Runnable SQL + Python filesEvery query and script from the guide, commented, working against the included sample datasets the moment you download.
-
Two sample CSV datasetsThe fictional retailer's orders and customers — so every example is something you open and run, not just read about.
Look inside before you buy
Two real excerpts, straight from the guide.

| 4–6 | Excel: pivots, XLOOKUP, data cleaning | Portfolio Project 1 |
| 7–9 | Power BI: DAX, dashboard design | Portfolio Project 2 |
| 10–12 | Python: pandas, automation | Portfolio Project 3 |

What this is — and what it isn't
A $19 "career accelerator" deserves a straight answer before you pay. Here it is.
A complete self-paced starter system. The full 90-day roadmap, beginner-proof setup and installation guides for every tool, a real end-to-end portfolio project, working Excel/SQL/Python files, and the 3 bonus guides.
One payment. Everything included. $19, once. Lifetime access, free updates, instant delivery by Gumroad, re-downloadable any time. No subscription, no upsell needed to finish the program.
The same skills bootcamps teach — SQL, Excel, Power BI, Python — the exact stack employers ask for, in hiring order.
Not a bootcamp. There are no live classes, no 1-on-1 mentorship, and no job-placement guarantee — programs offering those charge ₦175,000 to ₦1,000,000+, and that's a different product for a different budget.
Not a magic shortcut. You bring the discipline; the guide brings the structure, the order, and the answers to "what next?" so none of your effort is wasted.
Not padded theory. No filler chapters to justify a bigger price tag — it's the working system, drawn from real engagements, at a price a beginner can actually afford.
Questions, answered
I have zero experience. Is this really for beginners?
Yes — the guide assumes nothing beyond basic computer literacy. Every tool is introduced from first principles, in the order that actually matters for getting hired.
Do I need to buy any software?
No. Excel or Google Sheets, Power BI's free desktop app, and Python are free or already on your machine. Tableau Public (free) works too if you prefer it.
What exactly arrives after I pay?
One ZIP bundle: the full guide, the step-by-step Setup & Installation Guide, the working Excel workbook, the SQL file, the Python script, and both sample datasets — plus the 3 bonus guides as separate files. Delivered instantly by Gumroad to your email, re-downloadable any time from your Gumroad library.
Is the case study a real company?
No — "Northwind Retail Co." is a fictional business built specifically for teaching. The investigation pattern applies directly to real portfolio projects and real job data.
How is this different from free YouTube tutorials?
Free tutorials are organized by tool. This is organized by problem — you'll never wonder how the SQL you just learned connects to a dashboard, because you build that dashboard from that query in the next chapter.
