Working as a Software Developer Consultant for Walmart as a Web Developer on the international team to build a next generation checkout system for Walmart Canada.

I focus on the Front End using React and TypeScript, but I also help implement backend APIs and maintain communication between the web app and the physical devices cashiers use such as hand scanners.

I work with multiple teams and have implemented high end features for the checkout staff lane such as purchasing and reloading gift cards, implementing SMART Serve Certification, and integrating tax modification and tax exemption to individual cart items.

Trained and onboarded new team members.

Worked as a Web Developer to build and maintain web app products for multiple clients worldwide in 50+ languages. Worked in a modern development process alongside other developers, designers, and product managers in the Agile methodology.

Developed custom libraries and components in a React JS monorepo. Wrote 100% code coverage unit tests via Jest. Used Git and Jenkins pipeline for continuous development and integration. Documented processes and instructions in Confluence and Jira.

Career highlight: Personally enchanced the quality of our code reviews by dramatically improving our documentation for our pull requests.

Side Projects

Tile Game

Android app game made in React Native. Mobile game is based on the old school tile game where you need to rearrange tiled numbers to put them back in numerical order. Download the game on Android and give it a try!

A PWA unit conversions web app. Progressive Web App made in React to help convert common units of measurement between the imperial and metric system. This came in handy when I was living in Ireland and needed to convert from my American units to metric and vice-versa.

When visiting the web app on your phone, you should get a notification to add the app to your device. If you do, then the web app will behave the same as if you had downloaded it from the Play Store. This even works offline.
