I am currently working at JPMC as a front end developer. And my career started from designing the web pages using HTML,CSS, applying responsive web framework such as bootstrap, and using jQuery to make the pages dynamic. And then I started to learn about the Angular 1 on 2014, and 2015, and used it on one of my previous project.

And later on on 2016 I joined JPM Chase, I designed the front end api for the UI experimentation (a/b testing ) for chase online, so I used JS AOP library to change the behavior of the framework method, so we can change the style, content, and tempalte of chase online at run time, which means we do not need to deploy two or more version of our application, we only deploy one version and do changes at run time.

And the 2nd project I worked on is a SPA using React, redux, and this applciation will load chase.com through the iframe, so user can set up the UI epxerimentation by just clicking their mouse, and it will show the direct result of how it looks like, and also it will generate a JSON file which will be consumed by the chase.com to reproduce all those changes at run time. ~~We do the communication between the 2 applciaitons using the postMessage api. ~~And the 3rd project I am working on is just front end utility, which can be used for any chase application, such as the front end validation, dirty form, file downloader and uploader. And I also have a lot of experience in writing unit tests by using Mocha, chai, Sinon, and in the react applciation we use Jest and enzyme, because Jest will do all the worke which the Mocha, chai and Sinon will do.
