I worked as a contractor for one of the biggest taxi companies in Phoenix, AZ area. My main duty was to work with large amount of data that would feed internal web-sites with correct data about trips, cars, drivers and riders. The back end was done using Node.js and Sequelize to access the MS SQL server, and MongoDB to cache intermediate data for faster access. The internal websites were created using a mix of Angular and ASP.NET MVC.

I joined this company when they had a proof-of-concept SPA written with the first version of React, after Facebook had just released it. My duty was to fix bugs and add new features. As the product evolved, I realized that the current architecture is no longer extendable and proposed that we rewrite it using the modern React patterns, such as Redux and Router. I architected the new product, making it more robust and easily extendable. The addition of Redux allowed us to have all the data in one place and add unit tests. After this success, I was asked to develop two more applications for them, a kitchen visualizer with real-time updates based on user selection of the granite, and a back-end dashboard for the fabricators. Both projects were delivered in time.
