Build a Website

We are looking for an experienced Front-End Engineer to create a handful of similar client-side apps. Our system is based on a core REST API that will feed the several client-side apps to be developed. The system has different user roles, and we would like a client-side application for each of them. However they will be fundamentally similar CRUD interfaces, containing the usual elements: tables, lists, in-line editing, etc. Additionally all the requests will be made/secured by JWT-based sessions, as opposed to browser cookies. We are interested in someone/team capable of developing such similar applications in a well-known JS framework(Angular, Ember, React...) since that would probably allow us to find/incorporate new engineers easier in the long run. These are the skills we are looking for: - Experience building and deploying to production SPA/client-side apps. - Knowledge of JSON API communications. - Web design/Responsive design knowleadgeable ( not necessarily an expert designer). Alternatively able/willing to adapt Themeforest templates. - Extensive experience with Javascript. - Experience with one or more JS popular frameworks (Angular 1/2, Ember, React). - Knowledge of PHP (as required by some side sites of the company) - SSL certificate installation. - JWT Authentication via REST. - Unit Testing/Integration testing ( Mocha, Jasmine...) Our company is based in Costa Rica, but we are open to candidates living in other timezones.
