Alfredo Gerardo in a few words

Hi, nice to meet you! 👋

I'm Alfredo, a Web Developer who's been around both Frontend and Backend development. I'm constantly trying to expand my knowledge about new frameworks and ways to do things. Traveling and exploring new cultures and places is one of my favorite things to do. I'm very passionate about music, web design, and video editing. I like working in areas in which I have to learn and continuously expand my knowledge and adapt quickly to new situations.

What I can help you with:

- Planning greenfield projects and their Front-End architectures 📗

- Projects that involve complex Front-End infrastructures 🔍

- Redux and React's best practices. Migration from class components to hooks, custom hooks 💪

- End to end testing with cypress, integration testing with react-testing library. Testing best practices following the AAA principle 🧪

- Design brainstorming with Figma, and planing the user journey throughout the app! 💭

- Tasks breakdown, project planning, and following an agile methodology to have continuous feedback 💬

If you think all of the above sounds good, let's have a chat! 🙋‍♂️
