@carlosleite1

Oracle PL/SQL and backend software engineer at Credsystem, optimizing Oracle queries and integrating systems through REST APIs and Kafka.

At Credsystem, I develop with Oracle PL/SQL, Java, Golang, Python, and Mendix. I optimize SQL queries and Oracle objects, and integrate systems through REST APIs and Kafka.

I also create dashboards with MicroStrategy and Power BI. At Talentfour, I developed Oracle PL/SQL for financial systems and worked on application support and performance optimization.

Across earlier roles at Europ Assistance Brasil, Resource IT Solutions, Grupo Silvio Santos, and Drogaria Onofre, I worked in BI/ETL, Oracle, and support. My background includes more than 20 years in software development, and I’m currently studying Artificial Intelligence at Universidade de Fortaleza.
