William in a few words

Full-Stack Developer. UI/UX Designer 👌. Open-Source Contributor. Privacy Advocate. Code Teacher. 25 yo. GraphQL + React + React Native = ♥️

Je suis un jeune homme de 25 ans, passionné d'informatique et de nouvelles technologies depuis tout petit. J'ai toujours rêvé de travailler dans une société où mon amour du code, ainsi que mon perfectionnisme seraient acceptés. J'ai travaillé dans plusieurs entreprises, de la startup (20 personnes) à la megacorp (1200 personnes) et récemment décidé d'ouvrir EthicDevs !

Je développe ainsi des logiciels, des sites web et des applications Android et iOS (avec React Native). Tout cela, je l'ai appris par moi même, en autodidacte. C'est là ma plus grande force, je suis quelqu'un qui s'adapte et apprends rapidement, toujours en quête de nouvelles connaissances.

Je maîtrise le trio HTML5/CSS3/JS avec perfection. Je me dirige principalement sur tout ce qui touche à React, React Native, GraphQL, NodeJS ainsi que les codebases cross-platform (type electron, react-native-web, protonnative, etc).

J'ai de très bonnes connaissances dans les langages et frameworks que sont TypeScript, PHP, MySQL, SQLite, PostgreSQL, MongoDB, Vala, C, Crystal, Python, Ruby/RoR, Bash, React, React Native, GraphQL, Nexus, Apollo Server/Client, URQL, Prisma, React Native Web, Redux, Angular, TypeScript, AdonisJS, Node.JS, GraphQL, Nest.Js, Vue, Styled-Components, Firebase, Firebase Auth, Emotion, WebPack, Metro, Babel, Jest, Detox, Cypress et bien plus encore.

Chaque matin et soir, je prends 1h30 afin de faire ma veille technologique. Cela me permet de rester au niveau, et d'en apprendre toujours plus. Je suis amoureux du logiciel libre et de l'open-source. Je maîtrise les systèmes Linux et ses outils (git, unix commands, etc). Je passe un tiers de mon temps sur GitHub/Gitlab afin de maintenir mes projets, contribuer à d'autres, proposer des solutions ou encore rapporter des bugs.

Merci pour la lecture, et au plaisir de collaborer avec vous! 😁
