Pressure Ulcer Monitoring System

Published at September 10, 2025 ·  2 min read

Overview This project focused on building a medical system for pressure ulcer monitoring, combining a MIPI camera and a touch-screen interface on an NXP i.MX6 platform. The system was designed for clinical environments and required both low-level bring-up and user-space application development. Responsibilities Performed board bring-up for the i.MX6, including configuring the LCD touch screen. Integrated a MIPI camera module for real-time wound imaging and diagnostics. Modified and adapted the watchdog driver to fit the custom PCB....

Overview The Alyn project was a collaboration with the Alyn rehabilitation hospital, focused on creating an embedded system to support advanced assistive technologies. My role included both firmware development and integration with hardware for real-world patient use. Responsibilities Designed and implemented low-level embedded C++ code for microcontrollers. Worked with RTOS environments such as Zephyr and FreeRTOS to ensure deterministic performance. Integrated sensors and actuators through I²C, SPI, and GPIO. Developed safety mechanisms, telemetry, and diagnostics for medical-grade reliability....

Modular Data Injection Architecture for Embedded Systems

Published at September 5, 2025 ·  5 min read

Designing complex embedded systems — such as IoT devices, medical products, or industrial controllers — often requires supporting multiple hardware platforms: MCUs, Embedded Linux systems, and sometimes even mock environments for testing. To achieve clean separation between core logic and platform-specific implementations, I designed a modular data injection architecture based on virtual interfaces and dynamic backend registration. This post summarizes the approach and presents a practical C++ implementation of this architecture....
