A regional healthcare network had no unified operational view — executives couldn't distinguish structural failures from short-term demand shocks, and reporting was retrospective and fragmented.

Client was manually reconciling HR/payroll data between 2024 and 2025 employee datasets — slow, error-prone, and unable to detect ghost employees, underage employment, or suspicious salary changes. Built a one-click automated audit framework in Excel using Power Query, replacing the entire manual process with 15 systematic checks across data integrity, salary anomalies, workforce movement, and compliance — reducing processing time by 60%. Delivered full Power Query training so the client now runs and extends the system independently.

🔴Data Integrity (7 checks)

DOB mismatch across years, missing DOB (2024/2025), DOB after employment date, employment after valuation date, DOB after valuation date.

🟡Salary Anomalies (2 checks)

Salary decrease detection, salary increase >50% flag.

🟢Workforce Movement (3 checks)

Missing from 2025 records (ghost employee detection), new hires 2025, new exits 2025.

🔵Compliance & Policy (3 checks)

Underage at employment, underage at valuation, over-60 at valuation (retirement policy).

▸Built 15 automated M Language audit queries across 3 source datasets (EmployeeData_2024, EmployeeData_2025, ExitData_2025)
▸Detected ghost employees — records present in 2024 with no trace in 2025 active or exit data, impossible to catch manually at scale
▸Flagged salary anomalies and DOB/timeline integrity violations automatically on every refresh
▸Automated compliance checks for underage employment and retirement-age policy
▸Delivered full client training — one-click refresh, result interpretation, and adding new checks independently

Common Questions

Frequently Asked Questions

Everything you need to know before booking your first session.

No prior experience needed. We work with complete beginners through to intermediate and advanced users. During your free trial, we assess your current level and design the training around you — whether you're opening Excel for the first time or preparing for a senior analyst role.

Most sessions are conducted online via Zoom, which means we can work with students and professionals anywhere in Nigeria, the UK, and globally. For clients in Lagos, we can also arrange in-person sessions. All sessions are live and 1-on-1 — not pre-recorded videos.

AI training teaches you to use tools like ChatGPT, Microsoft Copilot, and Gemini to speed up your work dramatically — writing formulas, automating reports, summarising data, and more. If you use Excel, Power BI, or work in any data-related role, learning AI integration will make you significantly more productive and employable. It is rapidly becoming a required skill.

Tutoring is about teaching you a skill. Consulting is about solving your business problem. For consulting, we come in, assess your current processes, and build the solution for you — whether that's a Power BI dashboard, a Power Automate flow, or a full BI reporting system. We also offer corporate training to upskill your whole team as part of a consulting engagement.

Your first trial session is completely free. After that, pricing depends on the subject, session frequency, and whether you want a package deal. We discuss all of this during the free trial so there are no surprises. Book your free trial first and we will provide a transparent quote tailored to your needs.

Yes — corporate training is one of our core services. We design a customised curriculum for your team based on your industry, tools, and skill gaps. Training can be delivered onsite in Lagos, or remotely for teams anywhere in Nigeria or internationally. Book a free business audit and we will put together a custom proposal for your organisation.

Absolutely. All tutoring is available online worldwide. We work with clients in the UK, Europe, North America, and across Africa. We are 5-star rated on Superprof UK. Sessions are conducted over Zoom and we accommodate time zone differences — including evenings and weekends.
