Summary

Software engineer with 5 years building enterprise automation, ETL pipelines, operational reporting, and secure API integrations across Python, Java, ServiceNow, Snowflake, Elastic, Linux, OAuth 2.0, HashiCorp Vault, CyberArk, and AutoSys. Experienced in troubleshooting production automation, documenting system designs, and supporting cross-functional enterprise platform work.

Experience

  1. Freddie Mac May 2024 — Present

    Software Engineer II

    • • Built modular Python ETL pipelines around single-responsibility components for independent testing, reuse, and scheduled execution across enterprise data workflows.
    • • Integrated ServiceNow, Snowflake, and Elastic APIs to automate data retrieval workflows that previously required manual coordination across multiple systems.
    • • Pulled server telemetry from Elastic via API to generate operational reports supporting monitoring, troubleshooting, and capacity planning.
    • • Implemented OAuth 2.0 authorization flows for secure internal and external API authentication across automation endpoints.
    • • Managed sensitive credentials through HashiCorp Vault and CyberArk, eliminating local secrets handling in Python and Linux automation scripts.
    • • Scheduled and sustained recurring jobs through AutoSys and ServiceNow-defined intervals; supported operational follow-through when automation failed.
    • • Set up Python/Linux email automation for server-to-client communications tied to enterprise workflow notifications.
