Carlos M.

Vetted Data Engineering developer in Brazil (UTC-3)

I worked as a Software Engineer and as a Data Engineer on a Data Platform team at a company that stored roughly 10% of all electronic invoices in Brazil. That was billions of records in our databases, and everyday it received tens of millions more. My team was responsible for providing APIs for other engineering teams, both to ingest new records into our platform and to retrieve records based on various filters. These APIs enabled the engineering teams to develop new features for end-users without worrying about business logic, which database the data was stored in, data migrations, data consistency, etc. As a software engineer, I've developed event-driven microservices for real-time data processing and HTTP APIs. My day to day tasks included: * Doing discoveries to find out what the problem is and how to solve it * Designing the solution * Creating the tasks in our backlog * Build the systems with unit and integration tests * Make the CI-CD pipeline * Create alerts and monitor the system after it is deployed to production As a data engineer, I've built batch pipelines to migrate billions of records from one database to another in just a few hours and I would also maintain several Airflow DAGs that triggered ETL pipelines that populated data marts in our data warehouse. I was also Data Engineering Chapter Leader, responsible for tutoring junior data engineers, creating data engineering trainings, diffusing good practices and standards for creating pipelines and organize meetings to discuss technology and tools within the Data Engineering Scope. More recently I was being trained to become a Tech Lead. I took over my Tech Lead's responsabilites when he went on vacation for 20 days, which included talking to our manager to decide which projects to prioritize, help the team plan the weekly tasks, resolve major incidents and plan the next quarter roadmap.
