High Power Interface Tolerance Evaluation System

Embedded C Flutter AWS Flask

Senior Design Capstone at Texas A&M University in College Station, completed from August 2019 to May 2020. I served as the sole software engineer on a 4-person team building a safety-critical intermediary system for evaluating tolerance thresholds between high-power electrical devices.

Role

Owned the full software architecture across embedded firmware, mobile application, and cloud backend
Designed software around a hardware risk profile that required fault tolerance, redundancy, and predictable control behavior
Coordinated software interfaces with the rest of the team so the mobile app, embedded module, and test workflow could operate as one system

System

RTOS-based embedded system in C for real-time hardware control
Bluetooth connectivity for mobile communication, plus I²C and additional hardware communication protocols
Flutter mobile app for iOS and Android to serialize tests, format customer data, and communicate with the hardware module
Containerized AWS backend using Flask and PostgreSQL as the central data layer between mobile and hardware workflows
