PROFILE
Petro Zdeb
Worked on the datarobot-user-models repository, delivering features and security improvements across Python and Java environments. Focused on backend development, this engineer enhanced observability by overhauling logging, introducing X-Request-ID tracing, and standardizing error reporting. Security was strengthened through proactive CVE remediation, dependency upgrades, and environment reconciliation, including OpenJDK and core Python libraries. Containerization and CI/CD practices were applied to align local and production deployments, while modularity was improved by refactoring Java dependencies as optional extras. The work emphasized maintainability, risk reduction, and deployment consistency, leveraging skills in Python, Java, DevOps, and dependency management to support reliable model deployment.
