Embedded · Capability
Wireless Sensor Nodes
Low-power firmware for wireless sensor nodes — a layered architecture, host-side unit tests, and CI that can flash real hardware. This is how we approach embedded work.
- Host-side unit tests with Ceedling/CMock — logic is verified before a board exists
- Thin HAL keeps drivers swappable and the protocol stack fully mockable
- Low-power design patterns: Stop mode between measurements, peripherals power-gated

Touchscreen HMI Panels
Qt/C++ touchscreen HMIs on fanless Linux SBCs — live telemetry, configurable alarms, and a fast cold boot that runs unattended. This is how we approach industrial UI work.
- Qt EGLFS on bare Linux — renders straight to the framebuffer, no desktop needed
- Unified driver layer so Modbus RTU (RS-485) and Modbus TCP look the same to the UI
- Watchdog + systemd auto-recovery patterns for unattended, long-running deployments
