    • โ–ธDesign and operate ETL pipelines that ingest, transform, and serve large volumes of catalog and event data across the Prime Video Sports platform.
    • โ–ธBuilt a scalable VLM-based recognition system for automated event monitoring, deployed catalog-wide.
    • โ–ธDrove a cost-optimization effort that reclaimed over $350K in underutilized AWS resources in the first year.
    • โ–ธShipped a self-service image-slate portal and championed AI-assisted log diagnosis, cutting onboarding from two developer-days to none and enabling self-service root-causing for other teams.

    • โ–ธArchitected the firm's transition to Okta with in-house abstractions for other developers, reducing onboarding from several weeks to two days.
    • โ–ธOnboarded Datadog and built migration tooling from legacy monitoring platforms, cutting mean-time-to-root-cause from 9 days to 2.
    • โ–ธCreated CI/CD pipelines that made full Okta and Datadog adoption a one-commit change for most applications in the firm.
    • โ–ธDrove planning and execution of the on-premise to AWS migration, architecting bespoke solutions for internal teams as needed.
