Practical data work, explained in plain English.

A one-off analysis, a dashboard your team will actually use, or training to build confidence with data. Here is what I offer and how we would work together.

What I offer

Five ways I can help.

Each can be a one-off project or ongoing support, depending on what your team needs.

Data cleaning & analysis

Turn messy records into numbers you can trust.

Most organisations already hold the data they need, but it is scattered, inconsistent or sitting in a system nobody queries. I bring it together, clean it and explain what it shows.

  • A data health check of what you have
  • Cleaned, joined and documented datasets
  • Clear definitions for the metrics that matter
  • A concise written summary of findings

Tools: Python, SQL, Excel

Predictive modelling & machine learning

Plan ahead with models you can explain.

From energy demand and equipment faults to repayment behaviour, I build forecasting and machine learning models that support planning, and I document how they work so they are not a black box.

  • Forecasts with honest ranges, not single magic numbers
  • Risk and scoring models
  • What-if scenarios for planning
  • Plain-English model documentation

Tools: Python, Machine learning, Excel, MATLAB

Dashboards & reporting

Clear reports your team will read and use.

I design dashboards and reporting templates around the decisions your team makes each week, and automate the repetitive work of producing them.

  • Tableau, Power BI or Google Data Studio dashboards
  • Automated weekly and monthly reports
  • KPI scorecards
  • A walkthrough so your team owns it

Tools: Tableau, Power BI, Excel, Python

Operations & energy analytics

Find the waste in sites, buildings and equipment.

My background is in power systems, telecoms infrastructure and building maintenance. I know how to read fault records, energy data and asset logs in their operational context.

  • Fault and maintenance trend analysis
  • Energy consumption analysis and forecasting
  • Asset data clean-up
  • Advice on what to monitor and why

Tools: Python, CAFM systems, SCADA data, Excel

Training & mentorship

Help your team build confidence with data.

I have mentored analysts on the Full Stackers programme since 2023. I can run practical sessions for your team using your own data and your own questions.

  • Hands-on workshops in Excel, SQL, Tableau and Power BI
  • One-to-one mentoring
  • Process mapping sessions
  • Agile and Scrum fundamentals for data teams

Tools: Excel, SQL, Power BI, Tableau

How it works

Four steps, no surprises.

Every project is different, but the shape is the same, so you always know what is happening and why.

  1. 1

    An initial conversation

    We discuss the decision you need to make and the question behind it, so the work is aimed at the right outcome.

  2. 2

    A data assessment

    I review what data you hold and tell you plainly what it can and cannot answer before any significant work begins.

  3. 3

    Analysis and build

    I carry out the analysis or build the solution, sharing progress early so there are no surprises.

  4. 4

    Handover

    You receive the work, documentation and a walkthrough, so your team can continue using it independently.
