When I tell people I work at a payment infrastructure company, the reaction is usually one of two things: genuine curiosity, or barely concealed surprise. The surprise, I have learned is rarely about the organization. It is about me.

I am a Senior Software Engineer at Zone Payment Network, Africa’s first regulated blockchain network for payments. I work at the protocol layer, helping build the foundational rails that will power a new era of financial services across the continent and beyond. It is, without question, the most technically demanding and most meaningful work of my career.

It is also a field where women remain significantly underrepresented. And this International Women’s Month, I don’t want to just acknowledge that gap, I want to talk about what it actually takes to close it.

The Room I Walked Into

Engineering, especially at the infrastructure and protocol level, has a demographic reality that is hard to ignore. The deeper you go into the stack (into consensus mechanisms, smart contract architecture, on-chain settlement logic) the fewer women you tend to find in the room. That is not because women cannot do the work. I am proof that we can.

What I have learned is that the barrier is rarely technical competence. It is access, access to the right information, the right networks, the right rooms. And when you do get into those rooms, it is confidence: the quiet, persistent belief that you belong there just as much as anyone else.

Why Zone Changed My Perspective on What Is Possible

Joining Zone was a turning point. Not just professionally, but in how I understood the relationship between mission and momentum. Zones were not born from a trend; they were forged from over a decade of building banking and payment software for Africa’s largest financial institutions. The founders saw a broken system and chose to rebuild the rails entirely.

That kind of Courage, setting audacious goals and acting on them despite uncertainty, is embedded in Zone’s DNA. It is one of our core values, and I felt it from day one. When you are building the world’s first regulated blockchain network for payments infrastructure that eliminates single points of failure, automates settlement on-chain, and connects every financial institution into one all-inclusive ecosystem, there is no room for imposter syndrome. The work is very important. The stakes are too high, and you must show up and show out. That environment gave me permission to stop shrinking and start leading.

What Leadership Actually Looks Like from Here

Leadership in engineering does not always announce itself. It is not always a title. Sometimes it is the moment you speak up in a technical review when you know something is wrong. Sometimes it is staying in a complex problem long enough to find the elegant solution. Sometimes it is being the most senior woman in a protocol discussion and choosing to take up space, fully and unapologetically.

At Zone, one of our values is Proficiency because we are the best at what we do and we prove it with results. I hold myself to that standard every day. Not to prove a point about my gender, but because the mission demands it. We have built an infrastructure that connects previously excluded financial institutions into an all-inclusive payment ecosystem. That work deserves precision, depth, and excellence.

To the Women Considering a Career in Blockchain or Engineering

The technology is learnable. The concepts, as complex as they seem, are learnable. What no one can teach you is the decision to commit, to stay in the hard problem, to raise your hand in the room, to apply for the role that feels just slightly out of reach.

Zone’s vision is one global network to pay anyone, through any means, in any currency. That network will not be built by a homogeneous group of engineers. It will be built by the most talented, most diverse, most driven minds in the industry. Women belong in that number. We always have.

This Women’s Month, I am not just celebrating how far we have come. I am extending a hand to the woman who is standing where I once stood, at the edge of a room that does not yet look like her and saying: walk in. The rails are being built and you should join us.
