I build AWS supply-chain systems that scale hardware procurement and data accuracy.

At AWS, I built supply-chain infrastructure used to procure, price, and track hardware across global data centers. I re-architected the Physical Assets service into isolated customer partitions with production-shadow validation and no customer-facing disruption.

I delivered Dynamic Quoting, reducing manufacturer-submitted quote lines by 90%, and redesigned validation workflows to process 6,000 quotes per minute. I also migrated legacy offer data from MySQL to a DynamoDB-backed microservice and contributed fulfillment automation for AWS Outposts.

I lead design reviews, mentor engineers, and serve as an AWS hiring bar raiser. Earlier, I built .NET, ERP, CRM, and web applications across clients and industries in the Americas.
