E.ON
Development Lead - Full Stack
Projects : eon.de, mein.eon.de Tech stack : JS/ES6, TypeScript, React, Reflux, Node.js, REST APIs, MongoDB, AEM, HighCharts. I was asked to help rebuilding and refactoring the front end infrastructure of E.ON platform in Munich. Until then they had built their front ends with some frameworks and tools without any particular focus on it, resulting in a bloated and inconsistent codebase. That's why they asked me to lead the refactoring of their payment integration service, AEM author panel and their corporate website. The project was cut into several sub-projects and started with refactoring of the client integration service (payment dialogs) in December 2016, followed by the user backend in January / February 2017 and the corporate website in March and April 2017. In 2017, the payment dialogs and user dashboards have been completely redesigned and refactored with React, using Reflux as architecture and a consistent, clear design. We decided to use CSS modules in favour of the previously used PureCSS framework to follow a lean codebase approach. This set as our base I replaced several bloat-up jQuery plugins by custom written plain JavaScript snippets, such as a responsive slider, tabs component, mobile navigation, sortable tables and other small components. These saved hundreds of kilobytes in summary per project. Responsibilities : . Being the central point of contact and subject matter expert regarding front-end development. . Ensuring great user experience for end users by focusing on detail, speed, and fluency of the software. . Designing architecture and driving implementation of fast, scalable and maintainable frontend layer. . Working closely with project Tech Leads to support product development by appropriate assignment of tasks to developers and raising issues early. . Working closely with other stakeholders (Product Owners, Business Analysts, UX Designers, Graphic Designers, Sales, Marketing). . Representing development needs when it comes to front-end layer. . Developing front-end developers with regular feedback; mentoring, assigning challenging tasks. . Making employment decisions (in consultation with project Tech Leads) regarding hiring, promoting and firing decisions of front-end developers. . Building detail-oriented, collaborative culture, motivation and work satisfaction in front-end developers. . Promoting the company among front-end developers and other potential employees. . Implementing automated testing platforms and unit tests.
