Why Your Payment State Machine Is Probably Wrong
Most payment bugs are not bugs. They are design decisions that felt fine at the time and only revealed themselves when real money was involved.
Production-grade software. Real timelines. No surprises.
Simple solutions. Solid results. On time.
What we deliver
Every engagement ends with something you own: a brand, a product, a system, or a plan that your team can execute with confidence.
Real problems we were brought in to solve, and what we shipped.

Lightweight inference runtime for deploying vision models at the edge without a server round-trip.
Encrypted-at-rest PostgreSQL adapter with HIPAA-compliant audit trail baked in.
From the engineers
KraftCodes started at a terminal screen inside the math labs of Jomo Kenyatta University, where a small circle of engineers became obsessed with one question: why does so much software break under pressure?
The answer was never the code. It was the absence of architecture.
The Name
German. Noun. Power, strength, force.
01
We define every detail before we build, so there are no surprises in delivery. What we scope is what you receive, on time and working.
02
We build for the conditions that break other systems: real traffic, real load, real pressure. Not demo conditions. The kind that show up at 3am on a Tuesday.
03
We document every significant decision so your team inherits something they understand. Not a black box they have to reverse-engineer when we leave.
The Early Work
Not hypothetical problems. Each one forced a confrontation with what happens when the system is wrong and it actually matters.
Beyond the Build
Take a problem that seems too unstructured to engineer around, and build something precise and dependable on top of it.
Where We Are Now
Founded by Derrick Gitonga, KraftCodes partners with founders and teams building things that cannot fail. Engineering roots in Nairobi. Client footprint across London, the US, and Europe.
What we build
From FinTech infrastructure, custom school management systems, and enterprise ERP solutions to healthcare platforms, we build the systems that companies depend on when the stakes are too high for improvisation.
How we engage
We do not send you developers. We embed a team that takes ownership. Fixed scope, direct communication, and full accountability from kickoff to launch.
We build things that work. Then we make sure they keep working.
Built on the belief that the world has enough app builders and not enough architects.
