Senior Developer

MyTropolis Inc. Mobile App

Designed and built a mobile app to modernize Vancouver's downtown parking spaces by allowing city citizens to share their spaces. The app was similar to Uber, but for parking spaces. The completed product launched on time and on budget but was ultimately shut down due to a lack of product-market fit.

The app was build in React Native which connected to a Ruby on Rails API hosted on Google Cloud Platform.

eCommerce Sentiment Analyzer

Developed an API to analyze the sentiment of customer reviews on e-commerce products. The client had about 3,000 products in inventory, so automating the analysis of each plain-text comment from a customer was a scalable way for the client to understand how customers were receiving their products.

The API connected to Google Machine Learning services and was hosted on GCP.

Travel Time Analytics API

A Ruby on Rails API to gather travel time information from Google Maps services. The API provided endpoints to determine the travel time from point A to point B at any time of day, whether the user was walking, driving, or taking transit. The API also provided an endpoint for any combination of walking and transit, accounting for both busses and subways.

This API functioned by connecting to the Google Maps API and was hosted on Amazon Web Services.
