Matheus W.

I worked as a frontend engineer in the development of a risk management application for one of the largest payment processing companies in Brazil. My team was composed of a UX designer, a QA analyst, two backend engineers, and a Product Owner. My main task was to create a React application following accurately the layout specifications sent by the UX designer. I worked closely with the backend developers to integrate the pages I created with the REST API they developed. Another deliverable was a design system built from the components of this project. This set of components is now used across several other projects in the company.

A platform to promote short-term courses and other activities offered by one of the best private-funded universities in Brazil. Since the old website was not satisfying their needs I was hired as a solo full-stack freelancer to rebuild the website. My responsibility in this project was to develop a new frontend, responsive and built with React. I also modified the old PHP backend (built with Slim Framework) to be reused in the new website and I created an administration page to manage content. The administration was created with React Admin - a framework to create CRUD-based applications.

A non-profit Jesuit association with projects in education, social assistance, and spirituality. This organization manages several universities and colleges in Brazil as well as spirituality centers. I worked as a PHP developer. My tasks involved the development of websites for the projects of the organization and the maintenance of existing websites. Since several websites were built with Joomla, I developed custom modules and components to implement new features on these pages. Some modules required to extract data from the ERP system to publish to the public so I modified an internal REST API to make this data available.

I worked as a solo full-stack engineer in the development of web applications to support the processes involved in the front/back office department of a company. The clients I worked for were associations of workers, medical clinics and video producers. I developed modules for bookkeeping, payment of benefits and scheduling of appointments. The applications were developed with PHP and MySQL. The frontend was developed with JavaScript and some jQuery to make pages dynamic. For some clients, I developed institutional websites, including layout design. These websites were then integrated to extract data from the internal application we also developed. Other tasks - I was responsible for the provisioning of Linux servers and management (creation/backup/restore) of databases.
