I write about transitioning to tech here

  1. Embracing building in public image

    Embracing building in public

    When we build in public, we’re not just sharing our progress; we’re creating a ripple effect. Each update, each insight, and each challenge we overcome becomes part of a larger narrative that others can draw strength from...

    Trust the process

    Trusting the process is just being deeply rooted in the belief that your effort will pay off in the future even in times when it doesn’t seem like it. This belief might be hard to build at first but you can cultivate it by never losing sight of your goal...

Interests

Having worked in payments in the African context, it is clear that for the continent to unlock its full potential, there needs to be a significant increase in trade between African countries. Currently, intra-African trade is remarkably low, accounting for only around 15-18% of the continent’s total trade. This is a stark contrast to regions like the European Union, where intra-EU trade makes up a much larger proportion, often cited as over 60%.

This disparity highlights a significant opportunity for growth within Africa. Increased trade within the continent can foster economic growth by expanding markets, encouraging specialization, attracting investment, and building resilience against external economic shocks.

I’m exploring building solutions that facilitate seamless cross-border transactions, reduce trade barriers, and promote regional economic integration.

Fun

I recently rediscovered my love for reading. I read every chance I get now, primarily classic fiction. My favourite book is The Count of Monte Cristo by Alexandre Dumas. I’m a casual gamer, I mainly play FIFA/EA FC. I love indie/alternative music, play tennis, and I’m a long-suffering (but ever-hopeful) Arsenal FC fan.
