Designed and built a custom PCB-based embedded system integrating an ESP32 MCU, NRF24L01 transceiver, ILI9341 LCD, and custom input controls into a 3D-printed enclosure enabling real-time RF chess gameplay.
Designed and stabilized a shared SPI bus across modules by implementing manual chip-select arbitration and validating CPOL/CPHA timing.
Implemented low-level embedded firmware in C using ESP-IDF, configuring GPIO, SPI transactions, interrupts, and peripheral drivers.
Engineered a high-fidelity digital twin of an 800 V SiC traction inverter and PMSM system modeling switching dynamics and DC-link ripple under load.
Implemented state-space motor modeling, SPWM switching logic, and field-oriented control (FOC).
Designed a spectral degradation detection pipeline using FFT/STFT and PyTorch-based regression models.
Modeled signal-induced link degradation (SNR, BER, FEC effects) and dynamically adapted routing and congestion control to maintain distributed system stability.
