the brief

Moving money across borders still takes days and a form full of account numbers. Payflip settles it in seconds, to a name or an email.

what I didBuilt the React Native app end to end: onboarding, wallet, send and receive.Wired the stablecoin rails underneath so a transfer settles instantly instead of clearing overnight.Own the release pipeline: builds, crash reporting, and the 2am fixes.

the brief

Real estate, gold and private equity are assets most people can't touch. BREX tokenised them, splitting one high-value asset into units small enough to actually buy.

what I didIntegrated the EVM contracts that split a single real estate, gold, or equity asset into fractional, tradable units.Built the investor-facing flows for browsing assets, buying in, and tracking a portfolio across all three asset types.

Design it, build it, own it.

I started building because I wanted things that didn't exist yet, and I stayed because the interesting part is never the part you planned for. Three years in, that hasn't changed.

React and Node up front, Docker and cloud plumbing underneath, and the tangled problems that live in between. I'd rather understand the whole stack badly than one layer perfectly, since it means I can follow a bug wherever it actually lives instead of handing it off. Some of what I learn spills into open source; the rest ends up in my notes.

Got a problem that's more interesting than it is urgent? That's my favourite kind. Email is the fastest way in, and I read all of it.
