Live tracking map + courier API integrations
Rebuilding the real-time delivery tracking map using WebSockets and Redis pub/sub. 14 courier APIs are now integrated — the challenge is reconciling wildly inconsistent data formats from each partner. Hardest engineering problem I've worked on.
Active DevelopmentRobert O. Paxton · History & Politics
"Paxton's argument that fascism is better understood as a practice than an ideology — a set of behaviours rather than a coherent doctrine — is the most clarifying historical lens I've encountered this year. The chapter on fascism in power is uncomfortable precisely because it's so specific."
Charles T. Munger · Thinking & Mental Models
"Reading one talk at a time. The inversion principle and the latticework mental models idea have already changed how I think about product decisions. Munger's core insight — that wisdom comes from knowing what to avoid — is underrated in startup culture."
Mariana Mazzucato · Economics & Innovation
"The argument that the state has been the primary risk-taker behind most transformative technology is both convincing and inconvenient for Silicon Valley mythology. Processing what it means for how I think about public-private dynamics in African tech."

Zero to One
Peter Thiel
Third re-read. Still the clearest thinking on why you'd build something genuinely new versus optimising what exists. The monopoly argument applies to African markets more than people realise.
The Power of Now
Eckhart Tolle
More rigorous than expected. The distinction between pain (inevitable) and suffering (self-created) is genuinely useful — less so under real deadline pressure.
Meditations
Marcus Aurelius
A timeless guide to Stoic living. Marcus Aurelius' reflections on duty, virtue, and the impermanence of life are both humbling and empowering.
The Obstacle is the Way
Ryan Holiday
A practical guide to Stoic philosophy in action. Ryan Holiday's take on turning obstacles into opportunities is both inspiring and actionable.
The real bottleneck in African e-commerce isn't payments — it's trust. Mobile Money solved the payment problem. Nobody has fully solved the trust problem: how do you transact with strangers in a low-institutional-trust environment? That's a product problem, not a payment one.
Africa & CommerceMost AI productivity tools optimise for the wrong variable. They help you do more tasks faster. But task throughput is rarely the actual constraint — knowing which tasks are worth doing is. These are completely different problems, and the second one is much harder.
AI & BuildingEducation in Ghana might be the highest-leverage thing I could work on. One generation that learns to think clearly and use digital tools compounds for 50 years. Nothing I'm building in logistics or fintech comes close to that return on effort. I keep circling back to this.
EducationSolo founding is sustainable if you treat it as a craft rather than a grind. The grind framing is performative and counterproductive. The craft framing asks: am I getting better? Is what I'm building worth building? Those questions lead somewhere.
BuildingThe best product decisions I've made came from watching actual users try to do the thing — not from interviews, not from surveys, not from analytics. There's something irreplaceable about being in the room when someone is confused by what you thought was obvious.
Product DesignBuilding the live tracking layer for okSumame. Going deep on Socket.IO, Redis pub/sub, and connection state management at scale. The gap between theory and wiring up 14 different courier data formats is wide.
Most of our Ghanaian users speak Twi as their first language. Even basic conversational Twi changes the relationship with the team and shapes how I think about the products. It's slow going.
Investigating whether fine-tuning makes sense for Paralel Me's AI writing assistant, versus better system prompt engineering. Currently leaning toward prompts — the gap is smaller than the ML research suggests with good context injection.

SeriesStill the best piece of media about what it actually feels like to build something under relentless pressure. Every founder should watch it. The thing they get right that most startup content doesn't: the exhaustion is real.
Abstract: The Art of Design
DocumentaryRe-watching specific episodes. The Ilse Crawford episode changed how I think about intentionality in product design — the argument that space should serve human wellbeing, not the other way around, applies to software as cleanly as it does to rooms.
Bad Monkey
SeriesGenuinely funny. Vince Vaughn is unexpectedly excellent. Good Friday-evening watching when the brain is full.
Accra for a week of user research, okSumame courier partner meetings, and team catch-ups. Two investor introduction calls while I'm there — nothing formal, but worth exploring.
okSumame public beta. Courier integrations nearly complete. The merchant dashboard UX needs one more round of iteration and a proper closed alpha with 20 real merchants first.
Paralel Me public launch from beta. Hardest decision: pricing. The freemium model feels structurally right but the conversion threshold needs more thought. Running experiments over the next 6 weeks.
Long-form essay on trust dynamics in West African e-commerce. It's been sitting in my notes for months. Most important thing I know that hasn't been written clearly anywhere. Making time.
