Portfolio websites are generally easy to make; however, a little bit tricky due to the fact that they need to be responsive as nature. As someone with a portfolio, you're looking to attract people on all types of platforms, that includes desktop pcs, laptops, tablets, and mobiles, so it's best to have the website responsive.
My take on this project will be as follow: The website will firstly be created on Adobe XD and Adobe Photoshop. All the wireframing and design will be done on Adobe XD, and if needed, the project will move on Photoshop. After getting your approval, I move on to writing your website in HTML, CSS, and Bootstrap to ensure responsiveness.
