Caroda is a video advertising company. I work creating solutions to deliver video advertising on our customers websites using our own solution built, from the video player itself to the backend services.

I designed and lead the development of a microservice-based web application for a public healthcare service. We did everything from scratch, using industry standards such as OpenID Connect and FHIR v4. I wrote all the technical documentation for the project and mentored new recruits.

Technical lead

I started building a hybrid application on the healthcare sector. I worked on the frontend and collaborated on building a new backend from scratch. There I discovered the complexities of managing healthcare data and worked with FHIR v3 and v4, a beautiful standard for this typology of data.

I built a hybrid application using Cordova and React for a wellbeing company, that focused on interaction between users and content management.

Full Stack developer. Started with plain Java, and soon moved to tons of technologies. I mentored new recruits, designed applications and developed them, sometimes with a team, sometimes on my own. It was a place where creativity was of the upmost importance and we were encouraged to find the best possible technology to accomplish our goals.

Lead developer

JavaScript has evolved a lot since I started with it (and hated it deeply because of its lack of structure). Since ES5 everything got better, and with Node.js, it's virtually everywhere. Now, I got to admit I love it and have tons of fun using it.

I love JavaScript, sure, but when you have a project that starts getting bigger and you have to collaborate with others, Typescript is the way to go. 

I've used Node.js for backend development, specially using my beloved Nest.js and some Next.js backend features. I've also used for quick scripting or other tools like Gatsby.

React is my default choice when picking a frontend framework (or should I say library). I've also wored with Angular.js and later on with Angular 4, but React just clicks for me, specially since version 16. I love how simple its concept is and the modularity it offers with very little boilerplate, so you can focus on what's important: building something great from the ground up.

I learned Redux just for the fun of it, and I got deep into the rabbit hole: Ducks, sagas and so on. However, I soon saw that the brand new Context API of React made things just easier.

I've written Jenkins pipelines to build, test and deploy solutions. I've also worked extensively with Docker, writing Dockerfiles, adding layers on top of existing ones to customize behaviors, deploying containers based solutions using docker-compose. And to do all that, there are also tons of bash scripting involved, so there's that. :D

I love this Material Design implementation for React. It's true that we've seen Material Design way too much already, but this library is my reference when looking for a great design system. It's easy to use, customizable and well documented, so I've used in many projects, both personal and professional.

When I started in this career, I didn't start with git. We had SVN and later on Mercurial. Because of that, when I landed in git lands, I saw how awesome it was compared to the other two. Since then, I've tried to master it as much as possible, and focused on good practices that help keeping things tidy and useful, such as conventional commits and semantic versioning.

Your graphs are stored in Firebase so you can access them from anywhere, or, if you do not want to log in using your Google account, they are kept into your local storage and can be exported and imported in JSON format.
