On this project, we built an app for internal use, and it consisted of a multitenant system. Five PMI teams used it to manage the communication between headquarters and hundreds of employees and clients. The app uses an entirely serverless architecture of React on the front end and AWS Amplify on the back end.

As a front-end leader, my role was to do most of the UI/UX development as well as to participate in the build of the cloud architecture. It was also my responsibility to review code contributions from colleagues in charge of refining the UI visuals.

Because we were developing software for five teams with different needs, we had to make the application flexible enough to satisfy several hundred users that now use it daily.

To meet that challenge—while remaining flexible and the codebase safe and well structured—we developed the app using a test-oriented approach. We also used Cypress.io to run end-to-end tests on the whole system, ensuring that refactors and new implementations wouldn't compromise the existing app.

TrueFoundry is a web app and CLI that allows engineers developing predictive models to easily deploy their algorithms, test them, and visualize statistics and analytics about their model, smoothing their development workflow.

I covered the role of Senior Front-end Developer, and as part of my job, I:

• Developed the user interface for new features of the React multitenant app, enhancing usability and user experience.

• Investigated, isolated, and solved bugs across the web app. Collaborated with back-end developers and designers to find and implement the best user experience solutions for the web app, making the user flow more intuitive and fluid.

• Integrated third-party services for customer support and technical monitoring.

• Reviewed front-end code contributions from colleagues, keeping consistent React best practices and code maintainability patterns.

• Contributed to code maintenance by thoroughly using TypeScript and refactoring part of the app structure for consistency and easy navigability.

A React application for an architecture project management. I was the front-end developer for a second iteration of the application when it became a SaaS, and it expanded its functionalities with new features.

Some of my responsibilities included:

• Refactoring the app for a multitenant architecture
• Developing a new Kanban board feature integrated with the old list-style task overview
• Implementing real-time updates with GraphQL subscriptions

During the development, I was in continuous conversation with the back-end team (responsible for developing Node.js APIs) to find the best technical solutions to serve a smooth user experience.

In the team of four, we adopted an agile-inspired workflow, keeping communication fluid and adapting to different development steps as a team while taking responsibility to organize our work independently.

For Elion Digital, I developed the front and back end of an MVP for their web app, aiming at smoothing communication between people working in the world of healthcare.

Some of my responsibilities included:

• Developing the UI of a web app, connecting professionals working in healthcare simply and efficiently

• Coding the front end with TypeScript, React, and MUI, making decisions for best practices, and ensuring component reusability and good code maintainability

• Participating in designing data models to be stored in Firestore, a NoSQL database

• Writing database middleware rules and tests, securing the application’s data, and managing different user roles inside the application

• Writing Firestore Cloud Functions to keep data consistent across the database and reduce client calls to the minimum

• Working collaboratively with colleagues from the other side of the world, using Azure DevOps project management tools
