C++ · Python · OpenCV · ESP32 · YOLOv8 · Fusion 360

• Built a real-time embedded firmware stack on an ESP32 driving a 5-channel servo array via 12-bit hardware PWM at 50Hz, utilizing native PWM drivers without external convenience libraries.
• Wrote a custom 3D geometric Inverse Kinematics engine in C++ to convert Cartesian target vectors into joint duty cycles in real time.
• Implemented an automated wrist self-leveling loop to counter-rotate the end-effector and hold a stable posture through fast movements.
• Built a vision pipeline with a custom-trained YOLOv8 model to map pixel coordinates to physical workbench coordinates for closed-loop pick-and-place.
• Designed a parallel-tracking gripper with passive compliance, and every mechanical component of the arm, in Fusion 360.

C++ · ESP32 · TinyML · KiCad · I2C

• Wrote a bare-metal C++ I2C driver for an MPU-6050 IMU, parsing raw 6-axis accelerometer and gyroscope data.
• Built a spatial orientation and kinematics engine using Mahony sensor fusion and quaternion math, feeding an on-device Edge Impulse TinyML model across 10+ exercise classes.
• Engineered real-time peak-detection algorithms to identify rep boundaries and segment eccentric and concentric phases.
• Designed a custom two-layer PCB in KiCad integrating the ESP32 and IMU into a wearable form factor.

SystemVerilog · PyTorch · ModelSim · Quartus · DE1-SoC

• Architected an INT8 deep learning accelerator on a Cyclone V FPGA (DE1-SoC) for MNIST inference, engineering a custom post-training quantization pipeline with 20-bit accumulator-scaled biases to resolve input background DC offsets.
• Designed an RTL datapath featuring an 8-bit signed MAC engine, a 27-bit accumulator, and fixed-point hardware requantization (∗1462⋙20) with saturation clamping alongside custom ReLU and ArgMax modules.
• Implemented a multi-state control FSM executing full inference in 31,610 clock cycles (632.2 μs latency at 50 MHz), achieving over 1,580 classifications/sec verified on-chip via Signal Tap Logic Analyzer.

C++ · RISC-V Assembly · FTXUI · Linux

• Built a cycle-accurate CPU emulator in C++ decoding and executing the RV32I base instruction set, with a 32-entry register file and a 1MB simulated RAM system bus.
• Developed an integrated single-pass assembler to compile human-readable assembly into 32-bit machine code in real time.
• Built an interactive terminal debugger with FTXUI featuring live register visualization, aligned memory hex dumps, and single-step execution.

C++ · GTK · GDB · Linux

• Architected high-performance spatial data structures using hash maps and sets to index OpenStreetMap entities, enabling low-latency intersection lookups and street topology queries.
• Implemented geographic distance algorithms using spherical to Cartesian equirectangular projections and engineered set-intersection routines to identify multi-street junctions.
• Built an interactive GTK search interface featuring real-time autocomplete via case-insensitive prefix-matching algorithms and dual-point intersection highlighting.
