I specialize in creating user interfaces with great user experience. My main areas of expertise are Single Page Applications and Progressive Web Apps.
My main tools are HTML, CSS, JavaScript and React (which I've been using for ~10 years now).
I have experience in designing and implementing projects from scratch, as well as joining and supporting existing ones. I can work in a team or on my own.
I love CSS ❤️ and everything connected to how things look and work in a browser. I think UI Developer or Webmaster would be a better title for me. Show me any design and I guarantee I'll recreate it (or at least die trying).

Open Source
A React Hook that adds an animated ripple effect to any element on click. Quite proud of the 🌟 it has gotten on GitHub.
A React Hook for handling forms. A replacement for redux-form that doesn't require Redux.
Contains a Div component that makes flex-based positioning a breeze and a Bootstrap-inspired grid system.
It also has a height animation component (that I haven't documented yet).
An image lazy-loading plugin (README to be updated).
Games
I like to make a simple game once in a while. Here are some that are currently deployed:
A game about staying away from people breaking social distance. Keyboard required. My first Svelte project.
A Minesweeper-type game in JavaScript with jQuery. One of my first apps ever. Currently being refactored.
