About William Fontanetti

Simplicity is the soul of efficiencyHey! I'm William, a creative and curious Brazilian, who moved to Canada to seek new opportunities to learn and continue to build my career.I've always enjoyed creating new things, looking for new solutions, solving problems, improving an idea or even reformulating everything! I'm a nerd in my spare time, I love playing video games and also watching movies and series.I've been working with development for about 10 years, I started as a technical support in an internet provider and my last job was as a tech-lead in an agribusiness company. I'm currently working with Javascript, Typescript, React, React Native, NodeJS, MongoDB and Realm DB, but I can also work with PHP, C#, HTML, CSS, Angular, JQuery, SQL Server, Oracle DB and Postgrees SQL.I love solving problems — taking something complex and turning it into an organized framework of thought and strategy. I also learned that my curiosity helps me understand people; how and why they think and act the way they do, that's why I became a UI|UX enthusiast and I feel comfortable doing this kind of work, whether it's prototyping, creating designs or concepts, starting new projects, talking to users and customers to come up with a better solutionI love to challenge myself, so I'm always on the lookout for the next challenge, either in the workspace or as a side activity. I have skills in problem solving, team management and I like to be always learning new things.

Listed skills include Html5, Mysql, Banco De Dados, Css, and 28 others.
