Founder & CTO at EMENTECH · Nairobi, Kenya
I build software for Kenyan businesses — designed for local realities, built to scale globally. M-Pesa payments, SMS alerts, low-bandwidth optimization, real hardware constraints. If it doesn't work in the field, it doesn't ship.
B.Sc. Electrical & Electronic Engineering (JKUAT). The hardware background shapes how I think about software.
| Project | What it does | Stack |
|---|---|---|
| Dumu Waks · live | Maintenance & repair marketplace. AI-powered technician matching, real-time booking, M-Pesa payments. | TypeScript · React · Node · MongoDB · Docker |
| TomTin ERP · live | Multi-business POS for water packaging, laundry, retail, LPG. Mobile-first, offline-first. | React · Django · PostgreSQL · Chart.js |
| ArdaLink | Voice calls herders when NDVI drops 15% below baseline. Built for Red Bull Basement. | Python · FastAPI · Node · Azure OpenAI |
| TransitTag | IoT matatu transport — ride · pay · vibe. MQTT-to-WebSocket with M-Pesa. | C · libmosquitto · libwebsockets |
| Image Generator | Identity-preserving portrait generation with Strategy Lab comparison surface. | Python · Streamlit · Replicate · Fal.ai |

The six repos below are the ones worth your attention. Everything else in my profile is either coursework, scaffolding for what's next, or sleeping giants in waiting.

The infrastructure gap is real. Bandwidth is metered, payments are mobile-first, power is intermittent, and the customer is usually holding a 4-year-old phone in one hand. Software that ignores this isn't engineering — it's a demo.
I design for:
- Offline-first — the network is an enhancement, not a dependency
- Mobile money, not cards — M-Pesa is the rail; cards are the exception
- Low bandwidth — text where possible, images only when necessary
- Hardware-aware — if the chip can do it, the cloud doesn't need to
- Honest docs — if it doesn't work in the field, the README doesn't claim it does
