Mohammed Iliyas Pasha

• Embedded systems and electronics engineer with approximately three years of hands-on experience in embedded hardware, firmware, and signal processing for sensing and medical devices.
• Designed and developed end-to-end embedded systems, covering hardware architecture, firmware, and system integration for precision sensing, and medical devices.
• Designed multi-layer PCBs using industry best practices, including component selection, schematic capture, layout, power integrity, signal integrity, and EMI/EMC considerations, in line with applicable standards.
• Developed bare-metal and HAL-based firmware for ARM Cortex-M-based microcontrollers (STM32 series), handling peripheral drivers, timers, ADC/DAC, SPI, I2C, and interrupt-driven architectures.
• Implemented sensor interfacing and signal conditioning for differential pressure, calorimetric flow, gas, and acoustic sensors, ensuring accurate acquisition of low-level analog signals.
• Interfaced electrochemical gas sensors requiring low-noise analog front-ends.
• Designed and implemented analog front-end circuits, including amplification, filtering, biasing, and protection circuits for the microcontroller ADCs.
• Performed signal processing and calibration using MATLAB/Python, including filtering, curve fitting, linearization, compensation, and validation against reference data.
• Developed communication protocols and data handling for embedded devices, supporting reliable data exchange with PCs and external systems.
• Conducted system debugging and root-cause analysis using oscilloscopes, logic analyzers, and multimeters to diagnose hardware, firmware, and integration issues.
• Managed power management and low-noise design, including LDO/DC-DC selection, grounding strategies, and thermal considerations.
• Prepared technical documentation, including design documents, schematics, test procedures, calibration reports, and firmware documentation, to support development, testing, and the regulatory process.
• Collaborated on a prototype, bringing up testing and validation, while iterating designs based on performance, reliability, and manufacturability feedback.
• Followed structured development practices, including modular firmware design, version control, and systematic testing, to ensure maintainable and scalable codebases.

Regulatory and compliance exposure.

• Hands-on experience with pre-complaints and compliance testing of medical devices at TUV.
• Supported EMI/EMC, and safety testing activities, and implemented design changes based on test observations.
• Assisted in debugging and design modifications based on pre-compliance test findings to improve regulatory readiness.
