About

I'm an engineer in Toronto working at the intersection of communications and digital design. My work spans FPGA acceleration, signal processing and applied AI.

Projects

Deep learning computer vision system for chess piece recognition achieving 99.5% accuracy using ResNet-inspired CNN with OpenCV preprocessing.

Built an RF front-end that filters, downconverts, and amplifies 8–16 MHz HF signals with quadrature mixer producing phase-accurate I/Q signals for SDR integration.

Zephron: Robotic Arm Controller

Mar 2025 – Apr 2025

Real-time robotic arm controller using C on NIOS V soft processor with AXI memory-mapped I/O, custom PID loop, VGA dashboard, and I²C bridge for PWM servo control.

FFT-based spectral analysis on FPGA using SystemVerilog for real-time audio DSP with MATLAB filter ports to ARM Cortex-M for embedded benchmarking.

Technical Writing

A first-principles walkthrough of OFDM, from delay spread and coherence bandwidth to orthogonality and practical FFT/IFFT-based implementation.

An intuitive build-up from signals and Fourier series to the DFT and twiddle-factor symmetry, showing why FFT reduces complexity from O(N^2) to O(N log N).
