Professional Experience

- Mentor 3 Technical Account Managers in the audio segment of the Media & Entertainment portfolio—coaching on FinOps practices, escalation handling, and account strategy, and helping set delivery standards across the portfolio.
- Recovered $1.3M for a customer by uncovering a billing discrepancy outside standard TAM scope: a service billing at public rates instead of the customer's negotiated private pricing in regions launched after contract signing—undetected for six months, until the overage equaled roughly a full month of the account's cloud spend.
- Drove that remediation end-to-end across teams in the US, India, and South Korea—securing a contract amendment covering all current and future regions and building and defending the business case to senior executive leadership, who approved the full amount as a customer credit.

- Grew a major streaming and ad-supported media customer's cloud footprint more than 4x in monthly run rate over three years by driving adoption, architecture improvements, and new workloads.
- Drive FinOps and cloud financial management engagements—monthly billing and usage reviews, budgeting and forecasting, cost-allocation and tagging hygiene, rightsizing, cost-anomaly detection and root-cause analysis, and rate optimization via commitment planning (Savings Plans / Reserved Instances)—to align cloud spend with business value.
- Support high-visibility, large-scale live events for global media brands—coordinating cloud service teams, connecting customers with subject-matter experts, and protecting availability under pressure.
- Led a program to improve ad fill rates for a major media-streaming customer, applying Agile methodologies across multiple service workstreams to achieve a 24% increase over an 8-month engagement.
- Automate recurring reporting and operational tasks in Python, improving accuracy and freeing team capacity for higher-value work.

- Resolved a chronic failure across thousands of mobile computer carts—recurring power-board and cable burnouts—by proving the wiring-harness and board-connector design could not handle the electrical load; presented the evidence to the manufacturer, which accepted fault and replaced every board and harness with a redesigned version at no cost.
