ENGINEERING LOG // PROJECTS

Featured Full-scale Embedded System Projects

Over the years, I have work on a range of engineering projects starting from prototypes and MVPs to Design for Manufacturing (DFM). As the lead project engineer, I oversee the complete product lifecycle, including firmware development, hardware design, assembly, and deployment. Listed below, please find some of the projects.

BeeHappy IoT Solution

Merging apiculture with technology, the BeeHappy solution tracks hive weight, temperature, and humidity. This precision agriculture tool helps beekeepers optimize honey production and monitor colony health through automated data collection and analysis.

E-talking Stick Solution

A specialized Bluetooth-enabled microphone system designed for the US market. Integrated with AI meeting tools, this hardware features automatic timing capabilities and high-fidelity audio capture to streamline professional digital communication.

OpenHAP AQM Project

An indoor air quality monitor (AQM) focused on safety. OpenHAP detects carbon monoxide and other hazardous gases, bridging the gap between firmware and robust hardware to provide a reliable early-warning system for residential and commercial spaces.

Agha Khan HMI Solution

A custom Human-Machine Interface (HMI) designed for clinical excellence. This digital solution monitors Differential Pressure across hospital operating theatres, providing medical staff with instant visual feedback and data logging to maintain sterile, safe environments.

Songa Hub Station Solution

A powerful central gateway for electric vehicle infrastructure. Capable of managing up to 30 nodes via RS-485 and CAN bus communication, this MQTT-based station optimizes battery charging and swapping operations for electric trike fleets in Kisii Smart Community.

Songa Jinko Controller Solution

Songa Jinko Controller is an industrial-grade monitoring controller designed to interface with Three-phase Solar Inverters. It acts as the primary data acquisition and control master, collecting operational and electrical parameters from the inverters, processing them and publishing telemetry and events over MQTT.

Safaricom Cold Chain (Rafu)

An advanced industrial IoT solution leveraging BLE, GPRS, and WiFi connectivity. This system provides critical, real-time environmental monitoring for cold chain logistics, ensuring the integrity of temperature-sensitive goods during transit through remote telemetry and automated alerting.

HewaSense Project

A sophisticated environmental monitoring system designed specifically for modern office environments. This IoT-enabled hardware protects occupants from hazardous gaseous compounds by utilizing high-precision sensors and real-time data pipelines to ensure air quality standards are met at all times.
