PROFILE

Zac Blanco

Worked on the prestodb/presto repository over three months, focusing on modernizing the codebase and improving long-term maintainability. Upgraded the minimum Java runtime to 17 and ensured compatibility with Jetty 12, updating dependencies and providing transition guidance for Java 8 users. Enforced the use of the modernizer tool across all modules, removing outdated configuration flags in Maven pom.xml files to standardize code quality checks. Refactored core components to adopt Java Streams, replacing deprecated methods for better readability and performance. Demonstrated expertise in Java, Maven, and CI/CD practices, delivering cleaner, future-ready code without introducing new bugs during the period.

May 1, 2026

May 2026 focused on strengthening code quality and consistency in prestodb/presto by enforcing the modernizer workflow across all modules up to presto-main-base and removing the air.check.skip-modernizer flag from pom.xml. This alignment reduces maintenance burden, lowers risk of regressions, and future-proofs the codebase. No major bugs fixed this month; focus remained on quality, consistency, and long-term stability.
