Gabriel Pereira

As a member of the team responsible for a Platform as a Service (PaaS), I’ve been part of an effort that provides developers and QAs with personalized environments for comprehensive product testing and development. The platform leverages Kubernetes, with a backend developed in Elixir/Phoenix. The front-end is built in ELM, besides also having a CLI implemented in GO. My contributions to this team have significantly enhanced my proficiency in Kubernetes and cloud-based technologies.

XING is the lead professional social network in the DACH region. As a Backend Engineer, I have worked on the ProJobs team to build and relaunch the new Projobs membership and its respective features. In a smooth transition using the core of the existing one, and building a new backend using Phoenix/Elixir having its data exposed through REST APIs and GraphQL, the new product was released and has been receiving new features and improvements with good quality without loose time to market.

During this period I have worked on building a notification center backend using Phoenix and Elixir to become the central place for all mobile/web clients to retrieve through GraphQL the current notification information, fully enriched with all necessary data to be displayed and navigated by the end users.

During this period I have worked on a challenge migration extracting an important feature from a Ruby on Rails monolith to a Ruby on Rails API-only application. The project was successfully migrated and released without any downtime and any data loss. During this time I have worked remotely from Brazil, waiting for my Portugal visa work.
