Work Experience
Senior Software Engineer
Uber
- Worked in the safety team. Led the project to develop a service that processes safety information to classify the data, providing an understanding of the unstructured data used by other services that take actions based on the classification.
- Led some projects in the newly created team, which provided more safety and fairness to the platform customers. The data presented the need for a new area to manage safety and fairness issues.
- Designed and implemented a project per quarter, helping with the global rollout of a new product.
Senior Software Engineer
UOL
- Designed and implemented a modern cloud architecture for the email system and new services to integrate it. I also migrated on-premises systems to AWS.
- Developed the new email proxy, reducing the number of hosts in the cluster responsible for email protocol connections and internal integrations by 50%.
- Implemented an architectural change proposal, leading to a fourfold increase in the speed of migrating two petabytes of data between an on-premise data center and AWS.
Experience
UOL Email
I've worked on this project as a senior software engineer. My contributions spanned four crucial steps: developing the new services to support the migration, developing new services for the new architecture, defining and setting up the whole new infrastructure as a code, including monitoring tools, and running and monitoring the migration and the services running at AWS.
