Ideas into code.
Lessons into practice.

Production software, collaborative university projects, and focused explorations of the fundamentals. Each one added something to the way I think and build.

01 / FULL-STACK WEB

Grocery Price
Comparer

University project · Fall 2024

React / TypeScriptFlask-RESTXFirebaseSeleniumDocker

A grocery platform that connects shopping lists with retailer pricing and price history, making comparison more useful than a one-time search.

The build

A Vite-powered React interface communicates with a Flask-RESTX API. Firebase supports authentication and data storage; Selenium collects retailer pricing, and Chart.js visualizes price history. The application was containerized and deployed to DigitalOcean.

Engineering highlights

  • Connected frontend state, API contracts, authentication, and normalized pricing data.
  • Used longest-common-subsequence matching to associate free-text items with catalog entries.
  • Added caching and retention handling for collected data.
  • Configured headless browser scraping within a Docker deployment.

What this demonstrates

Full-stack integration, API design and validation, data processing, containerization, and user-focused workflows.

02 / REAL-TIME MOBILE

Hell On Earth

University project · Spring 2024

Unity / C#Firebase AuthCloud FirestoreOpenStreetMapAsync / Await

A location-driven mobile AR RPG with a GPS-powered 3D world, live player presence, and reflex-based combat.

The build

Unity and C# connect the game client to Firebase accounts and Firestore data. OpenStreetMap and Overpass provide spatial data for the environment, while asynchronous workflows coordinate networking, movement, and real-time updates.

Engineering highlights

  • Implemented account and profile workflows, session restore, and persistent character customization.
  • Connected GPS updates to world movement and map data retrieval.
  • Worked with real-time presence, proximity notifications, and synchronized player data.
  • Handled cancellable requests, update timing, and interactive combat state.

What this demonstrates

Client architecture, asynchronous networking, geospatial data, real-time state, and mobile user experience.
