Experience
You Just Go Travel Website
A website for travelers to be able to plan and book a trip across a country in minutes. It required only basic details like dates and number of travelers, and the routing algorithm would generate the best route. The user could reserve hotels and activities for every day of their trip, all in one transaction. While on the trip, they were accompanied by our travel companion app.
The application was built from the ground up in one of the first betas of Angular 2 and upgraded frequently up to Angular 6. RxJS was being used to implement events between components and services. A .NET Core API with MongoDB and Azure SQL was used as a back end.
I worked on transforming designs from our designer into HTML and SCSS.

Microsoft Azure for Partners Public Website
I implemented the Angular front end and headless CMS back end called Squidex for part of Microsoft's public-facing website, aimed at Azure Partners. I converted graphical designs into a responsive website with HTML, CSS, and Angular. I also implemented the back-end functionality using .NET Core C# and Node.js.
The designer would hand over designs in Zeplin and Adobe XD, and I would transform this into a responsive website using HTML and SCSS.

Bank Lending Application in Angular and .NET Core
Bank staff was using a legacy application to enter loan information. I've migrated this application to Angular 8, using NgRx and RxJS to build a reactive application. The application provided massive efficiency improvements for staff, saving them hours of repetitive work. I have implemented both front end in Angular as well as a back-end API in .NET Core. Besides development, I worked on unit tests and integration tests, using NUnit and Karma, end-to-end tests using Protractor, as well as CI/CD pipelines using Jenkins and OpenShift.

The designer would create designs in Visio which transformed into Angular components using HTML and SCSS.
