Have you ever had these issues when working a web site?

> why nothing happens when I click this button?

> why my backend API doesn't receive this ajax call?

>  or just how to build a web application?

I can help you with these with my 7 years of web development experience as a software engineer. I work on both front end and back end using technologies like javascript, html, css, jQuery, angular, asp.net etc.

I work with C# professionally for building web applications and web APIs on a daily basis. In my recent project, I designed and built RESTful API service. My work involved OAuth authentication, CORS, dependency injection, integrating with other backend systems, unit testing etc,.

I also mentored a junior level new hire to work on this project. 

My other projects include building web applications with ASP.Net MVC and ASP.Net web form.

I worked on many front end projects throughout my career using both pure javascript and jQuery library. I have extensive experience in developing and debugging javascript code. In my spare time, I also like explore some server side javascript functionalities using Node.js.

I have the chance to work on front end in my entire career. It's hard to do it without knowing HTML and CSS.

I have been using Angular 2 professionally for the last  year or so building a shopping cart experience. 

In the first few years of my career, my projects involved designing database for e-commerce websites, writing stored procedures for background data processing and t-sql optimization.
