Sharing What I've Learned

Lessons worth passing on

Short, practical takeaways in my own words — general principles, not any organisation's internal practice.

Data & DMI

Start from usage, not systems

When data work starts with a system inventory it stalls. Starting with how the business uses data shows quickly what matters and who cares.

Payments

A card approval is a promise, not money moving. Many product and reconciliation questions come from mixing the two up.

Open Banking

Rules set the minimum. Whether customers trust data sharing depends on how clearly the purpose and control are shown.

Risk & controls

A control that cannot show evidence it ran is hard to rely on. Design the evidence at the same time as the control.

AI Governance

Most AI risks trace back to data: where it came from, what it means and whether it is good enough for the decision.
