What I'm looking for

I seek senior engineering roles focused on cloud-native systems, payments or data platforms, where I can lead cost-optimization, mentor teams, and drive reliable, scalable architectures.

I am a lead software engineer with deep expertise in cloud migrations, payments systems, and cost optimization. At Capital One I led initiatives that improved cost visibility, governance, and operational efficiency across analytics and payments platforms.

I built portfolio-level cost transparency and dashboards that reduced unallocated spend by 58% and introduced cross-platform budgets with 90-day forecasts that cut plan-vs-actual variance by 17%.

I shipped optimization tooling (warehouse sizing, idle-time controls, query insights) and launched usage optimization programs that reduced Snowflake and compute spend for pilot groups while preserving SLAs. I also automated governance setup to standardize new environments and improve audit readiness.

I mentor and collaborate with distributed teams, drive cloud migrations with zero customer downtime, and focus on reliable, high-performance systems for card authorization and fraud/decisioning workloads.
