Web Developer

Why?! Ict Group

Zoeterwoude, The Netherlands

Building their new webshop for flower merchants. Prerequisites were: it must be build in C# ASP.Net because of the backend platform, it has to be as fast as possible and it must seem that all the products are all on the page so you can scroll through thousands of products.After a little research we chose React to do the JavaScript rendering for the product page. While scrolling React takes care of offloading and loading the DOM with articles so the page stays fast.I've focused primarily on the development of the product page where i've learned a lot about C# ASP.Net and the React library.
