Develop FreeRTOS/RTOS-based applications.
Develop drivers and integrate sensors, displays, memory and peripherals.
Work with UART, SPI, I²C, DMA, interrupts and timers.
Design modular, scalable firmware architecture.
Develop display and memory subsystems.
Integrate ECG, SpO₂, NIBP, Temperature, Respiration and other patient-monitor functions.
Debug hardware–firmware integration using oscilloscope, logic analyzer and JTAG/SWD.
Implement watchdogs, fault handling, diagnostics, bootloaders and firmware updates.
Optimize firmware for reliability, performance and memory usage.
Collaborate with hardware, biomedical and software teams.
Support verification, validation and productionization.
Mentor junior firmware engineers and interns.
