CPR.PT is intended to be a low-cost cardiopulmonary resuscitation training add-on used with a dummy to collect feedback and score technical maneuvers.

I worked on this project as part of my internship with FMUP, designing and developing the application's back end and front end.

I worked with an agile international team and took in an all-in-one HR software for small and medium-sized companies. The project's main goal was to migrate the whole app from a monolith to a monorepo architecture. Another goal was to improve the UI based on new designs. I implemented several widgets (Workflows, Approvals, My Absences Widget, among others) following the company's guidelines and with almost 100% test coverage as a senior front-end engineer. Additionally, I developed tools and workflows that enabled delivery teams to contribute to the design system (e.g., linter rules, pipelines, playground environments).

I worked with a remote team on the California Department of Motor Vehicles (DMV) platform. You can apply for an ID, register a vehicle, renew a driver's license, and more on this platform. I worked as a senior front-end engineer in implementing new functionalities and improving the performance of the application.

As the lead front-end developer, I was responsible for the architecture and implementation of the front end of a protocol for cross-chain token pools and also how it would connect with the back end. I managed a small team of front-end developers (three developers). I worked closely with the CTO at the time, Tiago Martins. Together, we implemented a brand-new design, added features, and migrated the app from Stimulus to React with TypeScript. To document the component library, we opted for Storybook. I also implemented Web3 integrations for wallet connections and contract integrations for multichain support. I developed unit tests and component snapshot tests using Jest and Enzyme. I created and assigned tasks to team members. I created convenient tools and workflows to enable team members to contribute to the design system (e.g., linter rules, pipelines, playground environments).

I collaborated and aligned with technical and non-technical stakeholders, e.g., designers, product designers, product managers, and engineering managers.

Served as a front-end developer building a mobile healthcare application using React and Ionic. A combination of artificial intelligence and sensors was used in the app to automate the inhaler technique. The device facilitates medication delivery deep into the lungs, improving outcomes for asthma, COPD, and cystic fibrosis patients. I worked on the authentication and authorization process on the dashboard and on several widgets to show the feedback on the inhalations and other helpful information.
