Featured Projects.
Designed a fully functional 8-bit Program Counter at the transistor level in Cadence Virtuoso. Built three sub-modules from scratch: a CMOS transmission gate MUX, a mirror adder ripple-carry full adder, and a master-slave D flip-flop register. Verified via full Spectre transient simulation.
Designed a 128-bit AES encryption coprocessor in Verilog on an FPGA SoC. Built a custom APB IP module in Platform Designer, implemented all AES transformations (SubBytes, ShiftRows, MixColumns, AddRoundKey), key expansion logic, and memory-mapped registers. Validated against NIST test vectors.
Designed a custom synchronous CPU at the RTL level in VHDL targeting FPGA. Architected a multi-stage datapath with register file, ALU, control unit, and memory interface. Developed FSM-based control logic managing fetch/decode/execute/write-back. Debugged in ModelSim, synthesized in Vivado.
Designed a hardware accelerator kernel in C/C++ for FPGA using Vivado HLS on a Xilinx Zynq SoC. Applied loop pipelining, unrolling, and dataflow architectures. Optimized memory via array partitioning. Analyzed HLS reports for clock, latency, II, and BRAM/DSP/LUT utilization.
Complete ARINC 429 Tx/Rx in VHDL on a Nexys A7 FPGA. Implemented 32-bit ARINC word formatting with label, SDI, SSM fields and odd parity. FSM receiver handles bit timing, word detection, and parity validation. Optimized in Vivado for minimal LUT/FF utilization.
Capstone: modified a Creality 3D printer to print directly from raw polymer, eliminating filament. Replaced control board with STM32-based SKR Mini E3, configured/modified Marlin firmware, tuned extrusion rate, temperature profiles, and motion synchronization. Enables recycled-plastic printing.

Real-time firmware in C using FreeRTOS on ARM. Task-based architecture for temperature sensing (ADC), control computation, actuator output, and system monitoring. Used queues and semaphores for deterministic inter-task data flow. Validated with oscilloscope-based timing analysis.
Wearable real-time obstacle detection for visually impaired users. Chest-mounted oscillating 2D LiDAR achieves effective 3D sensing. Cane-mounted rotary encoder detects traction loss. Directional haptic motors provide low-latency tactile alerts. Battery life ~12hr. Compliant with Accessible Canada Act.
Modeled and controlled a nonlinear magnetic levitation system. Derived equations from first principles, linearized the model, and designed hierarchical PI (inner current loop) + PID+feedforward (outer position loop) control. Validated in Simulink simulations and validated on real hardware via QUARC.
Designed an agent-based Sugarscape simulation studying how macronutrient distributions impact long-term fat loss. Modeled BMR, caloric deficit, and body-fat dynamics. Identified a stable optimal macronutrient ratio (~40/39/21) validated against real nutritional guidelines across thousands of simulation time steps.
Contributed features to the open-source Glances monitoring tool. Extracted and documented UML architecture, implemented NVMe-specific metrics (temperature, health status, performance tracking), added file system descriptions, and optimized metric displays. Managed sprints via JIRA, version control via GitHub, with comprehensive automated test suites.
