SYSTEMSWITH SOUL
I’m Emmanuel, a product engineer in Nairobi. I turn complex ideas into useful, human software—from language games to commerce infrastructure.

01 / SELECTED WORK
Built to be used.
Six products, prototypes, and tools from my current body of work.
ACTIVEEMMANUEL
Language learning, decoded
A Wordle-style cognate decoder that turns English words into a Spanish reading on-ramp, then reinforces each discovery with spaced repetition.

Selected build / private repository02 / OPERATING PRINCIPLES
Useful first.
Memorable always.
My work lives where product thinking, systems design, and hands-on engineering overlap. I like hard constraints, real users, and software that still works when the network doesn’t.
I move from the product question to the data model, interaction, deployment, and the last awkward edge case—without losing the idea that made the project worth building.
Design the whole loop
Connect content, data, product behavior, operations, and deployment.
Build for the real context
Offline modes, local payments, physical devices, and honest constraints.
03 / NEXT SIGNAL
Have a hard problem
worth building?
I’m open to thoughtful product collaborations, ambitious prototypes, and systems that need both engineering depth and a point of view.
