Independent data & technology consultancy

Untangle the data.
Understand the system.
Modernise with confidence.

I analyse messy data and complex software estates, expose risks and dependencies, and turn the findings into practical tools and plans.

When the question is...

Where did this number come from?

What breaks if we change this?

Should we update, rewrite or replace it?

Can this safely move to the cloud?

What I do

Clarity before commitment.

I work where data, software and business decisions collide—making the real situation visible before you spend heavily fixing the wrong thing.

02

Data lineage & tooling

Trace where data comes from, how it changes, what consumes it and what is at risk when something moves.

  • Field and table-level lineage
  • SQL, Hive, Spark and lake estates
  • Impact and dependency analysis
  • Purpose-built investigation tools
03

Whole-system assessment

Look across architecture, code, data, integrations and operations to find structural risk—not just the loudest symptom.

  • Estate and dependency mapping
  • Technical debt and risk review
  • Security and resilience considerations
  • Upgrade, rewrite or replace options

Applied AI for business

Human judgement at the wheel.
AI under the bonnet.

The advantage is not access to AI. It is decades of experience knowing how to direct it, challenge it and turn its speed into dependable business outcomes.

AI is extraordinarily powerful, but it does not replace judgement. Grease Monkey Labs uses it as a force multiplier across analysis, engineering, testing and documentation—while experienced human judgement stays in control. The result is the full, rigorous job delivered in a fraction of the conventional time and team cost.

  • Experience defines the right problem before AI touches it
  • AI multiplies the analysis, engineering and delivery capacity
  • Human judgement tests assumptions, risks and real-world fit
  • You get dependable working tools—not impressive-looking demos

Corners cutSenior judgement remains accountable for quality, risk and the final result.

The target is radical efficiency. The actual gain depends on the problem, data and controls required.

How I work

Start with evidence.
Finish with a decision.

No transformation theatre. I get close to the data and systems, test assumptions and leave you with artefacts that are useful after the engagement ends.

Talk through an assessment
  1. 01

    Observe

    Understand the business question, inspect the estate and identify where the evidence lives.

  2. 02

    Trace

    Map data movement, system dependencies, ownership gaps and hidden coupling.

  3. 03

    Assess

    Separate material risks from background noise and test the realistic options.

  4. 04

    Act

    Deliver a prioritised plan, working prototype or hands-on implementation.

What you leave with

Useful artefacts.
Not another mystery deck.

System & dependency maps Data-quality findings Lineage documentation Risk register Options with trade-offs Prioritised roadmap Working prototypes Bespoke tools

Experience

Built in the real world.

Experience across government, finance, telecoms, gaming and startups—working from board-level questions down to individual fields and lines of code.
