I’m an electrical engineering student interested in the connection between firmware, digital hardware, and physical systems. My projects span embedded audio, circuit design, FPGA peripherals, robotic mechanisms, and local software tools.

Hardware & embedded projects

Project Engineering focus Current stage
ESP32 MP3 Player Embedded C++, shared SPI display/storage, I2S audio, and button controls Hardware project with firmware and photo
PWM Fan Controller 555 timing, MOSFET switching, prototyping, and circuit debugging Circuit design and build report
MNIST FPGA Digit Recognizer Quantized VHDL neural network, VGA canvas, and PS/2 input RTL and Quartus source; simulation project
EEG32 32-channel acquisition board, hierarchical schematics, and PCB layout KiCad design; bench validation pending
FPGA Switch Counter VHDL edge counters, memory-mapped I/O, and SCOMP interfaces VHDL source subset; integration files pending
ESP32 Robotic Hand Parametric fingers, tendon routing, printable parts, and servo control Printed index prototype; powered tests pending
Mimic Animatronic Head Five-axis mechanism, CAD validation, and ESP32/PCA9685 commissioning Digital prototype; physical tests pending

Software projects

  • SignBridge — Local fingerspelling tutor using webcam landmarks, a NumPy classifier, temporal decoding, and a Qt interface.
  • ATS Resume Tailor — Evidence-based resume review, document export, and internship tracking with Streamlit and SQLite.
  • UFC Market Lab — Event capture, deterministic replay, a React dashboard, and simulated execution for market-data research.
  • Blackjack: Mafia Debt — Python terminal game with object-oriented design, JSON persistence, and interacting game-state systems.
  • Summer Command Center — React/Firebase dashboard for planning, habits, and daily reflection.
