Build me a clean personal portfolio website for Nicolas Lages that feels professional and simple to navigate.

It should have a home page, an about or presentation page, a school and career journey page, a skills page, a projects or achievements page, and a contact page. Use the existing CV PDF and logo files where it makes sense, and make the whole site look polished on desktop and mobile. I want a consistent header or navigation menu across all pages, smooth links between sections, and a style that feels modern but not flashy.

Make sure the content is easy to read, the layout is responsive, and the pages look like a real portfolio someone could send to recruiters. If anything is missing, use placeholder text that sounds natural and easy to replace later. Keep it lightweight and plain HTML, CSS, and simple JavaScript, and look up current best practices online if you need to.
