Fullstack dev/mentor

At Fizzmod I developed high-traffic e-commerce websites over the Vtex platform. Worked with Product to develop unique experiences integrating disparate sources of data into a seamless experience. Additionally built multiple desktop applications with ElectronJS for optimized applications.

Frontend Developer

During my first years as a developer, I worked with PHP and MySQL building CRUD systems for small businesses. I also developed several websites from scratch, including the designs, and worked on different requirements from these same businesses, such as email marketing and hosting configuration.

You've been trying to learn React but you still don't fully get it? You're not sure how hooks work, when to use them, or how the custom hook you have is working? Confused about class components vs function components? useEffect, react-router, or functions like .map and .filter still don't make much sense to you? If that's the case, or if you have something in React you need to fix or implement, drop me a message, I'll have the answer

Node is the present and future of web servers. It is not only used for serving files and database manipulation, but also for frontend everyday development, and that's one of the reasons why Node is so important for the web.

Javascript is my main language.

I've been using it since I started programming and I use it every day for building websites, apps and servers. I've used several libraries and frameworks and I know the latest features of the language.

If you need someone who knows Javascript, count on me!

The syntax is very similar to ReacJS; it actually uses JSX. But the performance of SolidJS is outstanding and this is one of the reasons you should be using it. Ping me if you need some help with Solid!

I have been creating, editing, refactoring, fixing and maintaining websites for more than 10 years. I've used professionally almost any HTML feature, including the latest HTML5 tags and attributes. I use semantic, clean and organized HTML and I always choose the best possible way to create a document structure.

If you need to learn HTML, CSS, or build a website, count on me; you'll see a great code quality on everything I do.

I've built a few Angular (+v2) and AngularJS (v1) apps and it is one of my favorite JS frameworks

I know in depth all the CSS potential with it's media queries, flex and grid layout, animations, transitions and every thing that can be styled and manipulated with this great language. I also use Sass/SCSS pre-processors everyday to be more time efficient and to improve code quality. 
Just let me know if you need some help with CSS.

jQuery has been here for a while and had always helped us to write shorter and cleaner code, more maintanable and easier to read. If you want someone who knows and really understands this great classic library then I am here to help.

 WordPress is a free and open-source content management system (CMS) based on PHP and MySQL. It allows users to modify the website easily without any programming knowledge.
