A financial transaction REST API. Built to explore systems design and inspired by the idempotent design of the Stripe API. The API models money as a value object, derives balances from the ledger at request time, and retries colliding writes with randomized exponential backoff. Unit and integration tests run in CI.
A full-stack work order management application built using TypeScript end-to-end and backed by a PostgreSQL database. Generates AI analysis of work orders using structured OpenAI model outputs. Automated tests, application logging, and error handling improve its reliability.
A Moodle plugin that visualizes real-time course data. This plugin served as the implementation component of my undergraduate capstone learning analytics research project. It implements Ajax-like dynamic chart refreshes, alongside a random forest model, trained using Python, that analyzed the relationships between learning behaviours and student learning outcomes.
