1,500 transactions, £1.9M processed, and a fraud problem hiding in plain sight. 20% of transactions were flagged fraudulent, but they accounted for 62.5% of transaction value, meaning the risk wasn't spread evenly, it was concentrated in a handful of customer relationships. I also found the bank's own risk categories were wrong: some "low risk" merchant types had fraud rates matching their highest-risk category.

174 on Contra. Top 1%.

I’ve spent the past few months refining my portfolio, case studies, and services, and I’m happy to see the effort showing up in my Discovery Score.

Let’s see what happens next. 🎉

If you run a busy team, I’m an operations and automation specialist. I help small businesses eliminate manual admin by turning repetitive tasks (like tracking forms, student/staff records, or timesheets) into automated background flows using Microsoft 365 tools they already pay for.

If your team is wasting hours copying data between Excel files or chasing updates, I’d be happy to build a quick, simple proof-of-concept flow for you.

Worth a quick 5-minute chat?

I designed a new digital experience for SackMoney, a fintech company that simplifies cross-border payments across Africa. The goal was more than creating a visually appealing website; it was to build a brand experience that conveys trust, simplicity, and speed, making a complex financial product easier to understand. From the visual direction to the website experience, every detail was designed to help turn visitors into users.
