I spent over three years developing an app using the latest Angular framework. I created new features and did bug fixing and optimizations on an ever-growing app that included GIS maps, charts, and a lot of data analysis tables.

I was the solo front-end developer responsible for creating and maintaining the entire site. The application was built using Angular 6 and Bootstrap for mobile-ready functionality. The app consists mainly of a stock-like chart for offering and demand of tax credits.

I worked really close to the CEO and was able to participate in the architecture of the apps really actively.

I was involved in the development of several Intel AppUp prototypes. This involved implementing an MVC design and writing APIs using Node.js and MongoDB.

Additional work included a number of UI/UX bug fixes, as well as using Redmine to track and address bugs in the code.

I wrote the front-end UI for the travel portion of the AmEx website using JavaScript, HTML5, and CSS3. Its features include infinite scrolling for hotel search results as well as an API for the Ruby back end.

This project features a user-friendly to-do app that uses Backbone.js on the front end and the SlimPHP framework for the API and back-end services, creating a well-structured, user-friendly, and high-performance application.
