About

A bit about me

I study Computer Science at Queen's University. I like building things: full-stack web apps, data tools, whatever sounds interesting and pushes me somewhere new.

I work mainly in JavaScript, Java, and Python. Outside of code, I'm usually hiking, playing hockey, or travelling.

Currently: Cerebro AI Technical Specialist @ FGF Brands · Queen's University

Markr — Stock Screener

Stock screener with a FastAPI backend, Redis cache, and PostgreSQL for range-partitioned price history. Pulls data from 6 sources (Finnhub → Yahoo Finance → FMP → Alpha Vantage → Stooq → Twelve Data) with per-source rate limiting via an atomic Redis Lua script across 12 REST endpoints. RSI(14), MACD, Bollinger Bands, MA50, and MA200 all compute client-side from raw price history; candle writes go async to a monthly-partitioned Postgres table.

Password manager with AES-256-GCM encryption (per-entry keys via PBKDF2 at 600k iterations), bcrypt auth, JWT rotation, TOTP 2FA, and HaveIBeenPwned breach checking via SHA-1 k-anonymity. 18 REST endpoints across auth, vault, password tools, and a security dashboard; containerized behind nginx with a pytest suite.

ctx — Browser Session Tracker

Local-first browser session tracker as a TypeScript npm workspace monorepo: Chrome MV3 extension, Hono/Node.js backend, and a CLI. Sessions batch via chrome.alarms and persist to chrome.storage.local with no server required. A privacy guard in the content script checks URL patterns, a sensitive-domain list, and live DOM fields (password inputs, credit card autocomplete) before capturing anything.
