I am a MERN/MEVN Stack Web Developer and I can build both the User Interface and the back end functionality of a website.
The type of websites I am confident to build are Portfolio sites, Business Sites, Ecommerce Sites. I have build many websites before, some of them which are now online. There is a site where I have the functionality to post and delete blogs but it all requires the user to be authenticated. There's another one where I have a list of products and an Ecommerce shopping cart that do all the calculations for items in cart.
Out of the two front end frameworks: React and Vue, I prefer React more than Vue, but I am confident enough to make UI with either of the frameworks.
The back end technology I have used in most of my projects is NodeJS with Express as the framework. And for the database, MongoDB just seems right to use with Node, even though I know SQL databases as well.
Work Terms
There is one thing though, I am not a big fan of taking projects that are way beyond my skill. So I will only apply to your offer, if I am certain that I am capable of delivering what it is that you require. You don't have to worry for your project to be dropped mid development!
