I Built Financial Systems, Then I Questioned Them: My Journey into Bitcoin and Privacy

There's a moment, when you've worked long enough in traditional finance, when something quietly stops making sense.

For me, it wasn't dramatic. There was no single breaking point, just a growing discomfort. I spent over five years as a software engineer building systems for banks and fintech platforms, systems that moved money efficiently, reliably, and at scale. On paper, everything worked: the transactions were fast, the APIs were clean, the UIs were intuitive, the infrastructure was solid. But underneath all that engineering elegance was a trade-off we rarely questioned: privacy.

Every transaction required identity checks. Every movement of value left a trail. Every user had to reveal more of themselves than felt necessary just to participate, and as an engineer, I wasn't just observing this, I was helping build it.

That realization crystallized for me one evening after a ride-hailing trip in Nigeria. At the point of payment, I received the driver's account number, and paying into it triggered an automatic name lookup and the driver's full name appeared on my screen. In turn, once he confirmed receipt, mine appeared on his. He now knew my name, and because he'd just dropped me at my door, he knew where I lived too. Neither of us had asked for that information. The payment rail handed it over as a side effect of doing something as ordinary as paying for a ride.
