I'm a full-stack developer and health informatics engineer based in Dar es Salaam, Tanzania. For the past six years I've been building systems that help governments and health programs collect, understand, and act on data, because better information systems mean better health outcomes for real people.
I lead a team of developers at HISP Tanzania, where we build and maintain DHIS2-based health information systems deployed across East and Southern Africa.
- Health information systems — DHIS2 implementations, custom apps, and data pipelines for ministries of health across Africa
- Public health data portals — making health data accessible and meaningful to the public, not just analysts
- Climate and health — exploring how climate data can improve disease surveillance and prediction
- IoT and connected systems — LoRaWAN-based tracking and sensor solutions using LilyGO/ESP32 and ChirpStack, from firmware to cloud dashboards
- Open source tools — reusable components, utilities, and frameworks for the DHIS2 ecosystem
- 🏆 2× DHIS2 App Competition Winner (2022 & 2025)
- 🌍 FlexiPortal deployed in Somalia, Mozambique, and Tanzania — enabling public access to DHIS2 health data
- 🔬 Contributed to DHIS2 core — API token naming and relative periods generation
- 📜 Five DHIS2 certifications across implementation, development, and analytics
- 📡 Built LoRaWAN-based vessel tracking systems using LilyGO/ESP32 and ChirpStack, bridging physical sensors to cloud platforms
- 🎓 Best Graduating Student Award 2020, Engineers Registration Board of Tanzania
| Project | What it does |
|---|---|
| DHIS2 FlexiPortal | Customizable public portal for sharing DHIS2 health data without authentication |

Frontend — React, Next.js, TypeScript, Tailwind CSS, Angular
Mobile — Flutter, Dart
Backend — Node.js, Express, Bun, Prisma, PostgreSQL
Health — DHIS2 (apps, APIs, metadata, tracker), CHAP, ERA5, CHIRPS
IoT — LoRaWAN, ChirpStack, LilyGO/ESP32, Arduino
Infra — Docker, GitHub Actions, VPS, PM2
I'm always interested in collaborating on open source health tools, DHIS2 implementations, or anything at the intersection of data and public health.
