As part of Airbnb’s Scheduling and E ciency team, I contributed to a reduction of approximately $2.2 million in infrastructure costs in 2022 by identifying key opportunities to streamline resources. This involved consolidating clusters, rightsizing sidecars, migrating services to optimize cluster usage, decommissioning unused clusters, and ensuring the deployment of nodes with optimal instance types. My tech stack included AWS, Kubernetes, Terraform, Chef, Buildkite, Spinnaker, Python, and Go, all of which supported a highly efficient and scalable infrastructure.In 2023, I moved to Airbnb’s Dev Tools team, where my focus shifted to enhancing the overall developer experience. I contributed to key initiatives that automated PR creation and streamlined the process of assigning reviewers and managing PR stages (e.g., in review, waiting for review...). These statuses informed CI processes to determine the next steps. My primary focus was on optimizing these systems for performance and improved logging.With Airbnb’s decision to retire Ruby, I was also leading the transition of all Ruby code to Go, Python, and Java, targeting a full migration by the end of 2025.

At Ília, I started transitioning into cloud engineering and had my first meaningful experience with AWS and GCP.Curious to know what that experience was? please, refer to: https://bcostabatista.medium.com/move-data-from-aws-rds-postgresql-to-gcp-bigquery-with-data-pipeline-part-1-d860d8af8413

As Engineering Team Lead at Science Play I am responsible for sprint planning for engineers, overseeing the deploy process, ensuring the team quickly responds when there are technical issues with the product, mentoring the Core Engineering team, pair programming when necessary and architecture reviews.

As Lead Developer and working alongside with the team we delivered a new software for the product. Stack: ReactJS, react-native, PostgreSQL, node.js and AWS

Using node.js, reactjs, react-native, angular and AWS, we developed a product designed to help companies bring their customers closer through a trade off program based on how much their customers score in the platform.

I started by writing scripts for automated tests using selenium and later developed the periodicals portal of CAPES. As a PHP developer, the work was directly with PHP, MySQL and JavaScript

As a developer, I actively participated in the development of the new CASSI portal (Assistance Fund of the Brazil Bank staff). We used joomla, SQL Server, IIS7, also we had to setup load balance servers and all the required infrastructure to get the project up and running

As a tester, I was responsible for writing scripts to automate tests using selenium.
