Data analyst · Manchester, UK

Data that holds up, from the field to the boardroom.

I help teams make sense of messy operational, energy and financial data, then explain what it means in plain English so they can act on it with confidence.

About me

An engineer's discipline, an analyst's curiosity.

I am a data analyst and data scientist with a foundation in electrical and power systems engineering. I specialise in data analysis, machine learning and predictive modelling, turning complex operational and financial data into insight that decision-makers can act on.

My career began at a 330/132kV substation, recording load and energy data where accuracy is critical. Since then I have used Python, SQL, Excel and Tableau to forecast energy demand, automate reporting and reduce operating costs across the telecoms and energy sectors. Today I work as a Data Scientist with 10Alytics in Manchester, and mentor emerging analysts through the Full Stackers programme.

What I do

Four ways I help teams use their data.

Each area below comes with a real result from my work, so you can see exactly what it looks like in practice.

Data analysis

Turning raw records into clear answers.

I clean, combine and explore data to find out what is really driving performance, then check the findings against what is happening on the ground.

For example: Found the recurring faults behind a quarter of Oldham Council's emergency repairs.

Predictive modelling & machine learning

Using past data to plan for what's coming.

I build machine learning models that forecast demand, consumption and risk, so teams can act before costs rise or problems occur.

For example: ML energy forecasts improved energy use efficiency at telecom data centres by 15%.

Dashboards & reporting

Putting the right numbers in front of the right people.

I design dashboards and reporting templates in Tableau, Power BI, Excel and Google Data Studio that decision-makers can read in minutes.

For example: A Python and Excel reporting template made project reporting 30% more efficient.

Energy & operations analytics

Making sites, buildings and equipment run better.

After nearly a decade in electrical and power engineering, I understand where operational data comes from and what it means in practice.

For example: A data-led network consolidation cut operating costs by 18% and capital spend by 22%.

Published opinion · New Telegraph

Better data could close a ₦12 trillion funding gap.

In my New Telegraph opinion piece, I argue that many Nigerian small businesses are turned down for finance not because they can't repay, but because lenders can't see the evidence. Their payment and cash-flow data could change that.

Mentorship

I mentor new analysts through real business problems.

Since 2023 I have mentored new analysts on the Full Stackers Mentorship Programme, teaching Excel, SQL, Tableau and Power BI with a focus on practical, job-ready skills rather than textbook exercises.

How I can help

Ways we can work together.

You might need me if…

You have plenty of data but no clear answers.
Your reports take days to build and nobody reads them.
You keep fixing the same problems over and over.
Your team wants to get better with data, fast.
