About

I'm Augustine, a Computing student at Queen's University (BSc, expected June 2028) who genuinely enjoys the full journey of building software — from sketching out the architecture to shipping something people actually use. I've worked across full-stack web development, computer vision, and system-level programming, and I care a lot about writing code that's clean, reliable, and easy for the next person to pick up. Whether I'm integrating a payment pipeline, building a real-time UI, or just making a feature feel right, I like doing it properly.

• Led demo execution at CUCAI 2026 for a Python application showing skeletal overlays and 3D vector-based angle calculations with an 8-frame smoothing window, presenting to physicians and competition judges.

• Wrote technical documentation that turned the team's orthopedic feasibility research into step-by-step reproducible workflows, cutting onboarding time for new contributors.

JavaScript / Web Developer Intern

NORCAT

May 2025 – Aug 2025 • Sudbury, ON

• Architected and shipped production-ready full-stack features across an e-commerce platform and internal admin dashboard, turning loosely defined requirements into clean, maintainable code that noticeably tightened product, inventory, and pricing workflows.

• Built role-based authentication/authorization across all core operational flows backed by MS SQL, meaningfully improving data integrity and platform reliability.

• Owned end-to-end Moneris payment integration, hardening the checkout pipeline with thorough validation and transaction logic to ship a secure, production-grade order flow from cart to confirmation.

Project Manager

Projects

TextBin

textbin.app

Architected and launched a production note-taking platform on Next.js 15 and PostgreSQL, with server-side AES-256-CBC envelope encryption — per-note keys protected by a master key — that keeps user data secure at rest without hurting performance. Built a full monetization layer with Stripe subscriptions, premium feature gating, and resilient billing/error handling, plus Better Auth sign-in, Resend email scheduling, and CI/CD on Vercel.

Peckodoro

peckodoro.vercel.app

Brought Spotify Web API (OAuth2) and OpenAI API together into a single Pomodoro interface, so users can manage focus timers, music, and an AI study assistant without switching tabs. Shipped on Vercel with Git-based CI/CD, cross-session settings persistence, and careful state and error handling that makes the app feel solid across real study sessions.
