PROFILE

Herval

Worked on the mobile-dev-inc/maestro repository to enhance JavaScript engine isolation, standardize build environments, and improve API analytics. Developed sandboxing tests for both GraalJS and Rhino to ensure restricted modules like fs remained inaccessible, strengthening security and test reliability. Standardized the build environment by aligning all modules to Java 17 using Gradle Kotlin DSL, which improved build consistency and reduced version conflicts. Enhanced the trial API by adding a referralSource field to /v2/start-trial requests, enabling better attribution and analytics. Leveraged Kotlin, JavaScript, and YAML to deliver reproducible builds, robust backend integrations, and comprehensive automated testing across the codebase.
