Case studies

Each one follows the same shape: what the business faced, what I recommended, and what changed.

  1. The business case for moving 500+ workloads to AWS

    A licensing increase and a hardware refresh forced a decision. The cost-benefit analysis made the case for AWS, and a redesigned disaster recovery model cut DR cost by 40%.

    • $1.5M capital spend avoided
    • 300% licensing increase offset
    • 40% lower DR infrastructure cost
    • Recovery time under 4 hours

  2. Connecting 80+ locations to the cloud with SD-WAN

    Contributing to a Cisco SD-WAN Cloud OnRamp architecture that routed traffic by application and helped cut cloud networking operating cost by 20%.

    • 80+ locations connected
    • 20% lower cloud networking operating cost
    • Better application performance and network resilience

  3. Managing a $2M converged infrastructure refresh

    Owning $2M in vendor spend for a Cisco FlexPod refresh — evaluating proposals, validating the solution and keeping production available.

    • $2M vendor spend managed
    • Proposals validated with vendor account teams before commitment

  4. Routing email with a self-hosted language model

    Running a large language model on in-house GPU hardware to classify incoming email and route it to the right queue, without sending it to an outside service.

    • Email classified and routed automatically
    • Data kept on company infrastructure
