Developing UI is one of the best things I like to work on! More than 7 years of experience working with user interface development using JavaScript in several projects, including native apps using React Native. With each project developed, I gained experience in both the simplest and the most complex web and mobile applications. In these projects, features were developed such as customised components, forms creation and dynamic lists in a CRM, as well as an automatic application generator or rich interfaces with options to drag and drop elements, complex components with perfect design with perfect pixel details and complete applications being created and handled directly based on the user's permission. The frameworks used were the most modern such as Ext JS and React JS/React Native with bootstrap and other templates. Also as a team leader, I worked as DevOp monitoring tasks and revising codes to bring better quality and performance to the application in the visual part and also thinking about the ease of maintaining the application. As a member of the Sencha MVP group, I keep using the best practices for projects using Ext JS with mastery over the source code of the framework for developing overrides and custom components. Also I have been writing some blog post for Sencha blog page. My skills include Ext JS, React JS, React Native, Javascript, CSS, SASS as well as other tools needed for a successful UI. I will be very happy to work on the front end of your project, with high quality applying the best practices. Get in touch and I will have the best option for your project! I have - Strong MERN stack experience - Expert knowledge of ES6/React/Redux/Next/Webpack/Babel and assorted technologies - Strong proficiency with Node.Js/Sails.js + Express.Js - MaterialUI / Reactstrap for building UI - Experience with D3.js, WebGL/Three.js - Experience with GraphQL - Strong understanding of browser compatibility issues (including mobile) - Serverless Environments (Azure Functions, AWS lambda) - Expertise in writing unit, component and integration tests for a React codebase using Mocha/Chai/Jest/enzyme/react-testing-library - Expertise in administering Linux server systems - Expert knowledge of HTML/CSS/Tailwind, responsive design and the Web ecosystem - Experience in implementing OAuth integrations - Experience with RESTful services - In depth knowledge of git and git workflows
