Mechatronics Engineering Student @ JKUAT, Kenya
Building practical hardware–software systems that solve real problems.

I design and build end-to-end mechatronic systems — from PCB and embedded firmware to IoT connectivity and web dashboards.

My work focuses on creating solutions that are not only technically sound, but deployable, low-power, and useful in real-world conditions, especially in agriculture, water systems, and autonomous platforms.

• 🎓 BSc. Mechatronic Engineering — Jomo Kenyatta University of Agriculture and Technology
• ⚙️ Focus: Embedded Systems · IoT · Motor Control · Hardware Design
• 🎯 Goal: Turn engineering principles into working systems that create measurable impact

• Low-power IoT devices for livestock monitoring and geofencing
• Open-source motor control hardware (ESCs) for drones and robotics
• Practical engineering solutions for water harvesting and rural applications
• Full-stack systems that connect sensors → firmware → cloud/dashboard

Problem: Free-grazing livestock are difficult to monitor for location, health, and activity.
Solution: A low-power ESP32 + LoRa electronic tag with GPS geofencing, accelerometer-based activity tracking, temperature, heart rate, and SpO2 monitoring, paired with a real-time web dashboard.
Stack: ESP32 · LoRa · FreeRTOS · GPS · Sensors · Next.js

Problem: High-performance, open-source, and compact 4-in-1 ESCs for custom drone builds are limited.
Solution: Custom 4-in-1 Electronic Speed Controller based on STM32F407 + DRV8323RS gate drivers, designed for 4S LiPo and ~7A continuous per motor. Full schematic and PCB in KiCad.
Stack: STM32F407 · DRV8323 · KiCad · BLDC Control
