This is the repository of my portfolio. Feel free to look at how it was made or to check it out here.
The languages I am most familiar with are javascript and C#.
I've also had the chance to use, very briefly, PHP for web projects.
I've been using React.js for a few years and just started to deep into Next.js for SSR.
I've also developed a small game with Unity that you can check out here.
Although I haven't used Bootstrap for my portfolio, I have used it daily for at least 2 years, with or without SCSS.
