Now
I'm a Computer Science & Statistics student at the University of Toronto, contributing to open source and tinkering with cybersecurity and programming.
Day to day, that's a mix of coursework and freelance IT consulting. I've previously helped organize GenAI Genesis, a nationwide student AI hackathon, and Google Developer Group events, served as Executive Vice-President at AMACSS, and worked as a machine learning developer at UTMIST on a signal-processing project for an external company. Away from the keyboard, I train for mountain ultramarathons and lift weights.

Experience
-
Information Technology Consultant
Freelance
- Integrated, containerized, and fine-tuned a PHP-based CRM for a critical-infrastructure company, cutting maintenance costs 23% and saving 30 minutes/day of repetitive work.
- Cleaned up and migrated a production database to MariaDB with SQL, shrinking it roughly 50× with no data loss.
- Wrote Bash and Python scripts to automate backups and administration, cutting backup and recovery costs by 70%.
- Built Arduino-based monitoring for critical industry systems, averaging $1,300 saved per false positive and preventing production-line shutdowns.
-
Machine Learning Developer
UTMIST · for Aercoustics Engineering Ltd.
- Designed and trained PyTorch models to classify sound events on construction sites for automated noise-compliance monitoring, cutting false-positive detections 30% and lifting detection accuracy from 85% to 92%.
- Evaluated models on precision, recall, and F1, and diagnosed class-imbalance and data-quality issues, improving detection consistency 15% on underrepresented sound events.

Selected projects
Three builds up top, eight more below.
Recreating images with pizza
An evolutionary algorithm that rebuilds a target image using nothing but overlapping pizza-slice shapes. Each generation mutates shape, position, and colour, kept only if it scores closer to the source.
Raytracer, written in C
A ray tracer built from first principles in C: camera rays, intersection tests, and shading, with no graphics libraries to lean on.
UNIX-like operating system
Built out an operating system across four stages: kernel threads, user program execution, virtual memory, and a persistent file system. Each stage built directly on top of the last.
