Santex
- Led a team of eight developers to build a web application to help universities create new career plans.
- Developed a web application to help the human resources department to store information about new candidates and open searches.
- Created a set of web applications for the healthcare industry. These applications ease the management of payers, clients, and transactions. I've used microservices, and different front ends.
- Developed a web application for dentists to manage cephalograms.
- Designed the templates for a codility-like website. They were built using just CSS and pure JavaScript/JQuery.
- Served as the technical leader of an app for a fintech that evaluates clients' portfolios. This application had several security layers that the team needed to comply with using React, like setting 2FA.
- Created two-component libraries with React using Bootstrap 4, Google Material-UI, and Storybook. They had everything necessary to build a complete application, and it was also customizable.
- Built multiple micro-frontends using a single-page app. This library allows your application to embed other front end built-in frameworks like Angular or React. They are loaded on demand, so the final app bundle is lighter.
- Handled real-time subscriptions to communicate changes to the UI while they were taking place. Some of them use GraphQL and in other projects use libraries like subscriptions-transport-ws.
- Worked with multiple authentication providers like Auth0, Firebase, Google, and Facebook. Furthermore, I developed auth integrations with user/email and password using stateless systems like JWT or stateful ones like managed sessions.
