Software Engineer · Nairobi, Kenya 🇰🇪
Backend, desktop, mobile — I build products end to end.
Python and TypeScript on the server, C# on the desktop, Dart when it needs to be in someone's pocket. I've shipped multi-tenant web platforms, a Windows application that runs AI models on the user's own GPU, and an Android build signed and packaged for the Play Store.
🔭 Right now — a C# redaction application on .NET 10 running GLiNER and whisper.cpp locally through ONNX Runtime with DirectML, so nothing a user redacts ever leaves their machine.
🧩 The bug I'm proudest of this year — two NuGet packages shipping competing builds of the same native library to the same output path, silently forcing every AI detector onto the CPU while the startup check reported GPU acceleration as available. Found it in one line of a field log.

|---|---|---|
| Platform (Django + React) | 461 / 2,027 commits · 3rd of 9 |
Per-tenant branded email, a generic real-time broadcast layer, OAuth mailbox refresh, multi-tenant isolation fixes, knowledge base, shared component library |

Local ONNX/DirectML inference, OCR coverage tracking, canvas editing, page operations |
| Survey product (React) | 17 / 41 commits |
Search layer, legal pages, domain migration |
Before engineering full time: seven months on the ICT service desk at Kenya Power — Windows support, LAN/WAN and Cisco kit, VHF/HF radio. It's why I read logs before I guess.
