Staff software engineer specializing in distributed systems, high-throughput APIs, and ML productionization with secure platform delivery.
United StatesWhat I'm looking for
I’m a Staff Software Engineer with 10+ years of experience solving technical challenges in distributed systems, high-throughput APIs, workflow orchestration, ML productionization, mobile modernization, and secure platform delivery. I focus on improving reliability, scalability, release velocity, and AppSec posture across complex production environments.
At Amazon, I’ve built and owned platforms across Flex, Sustainability, Prime Now, and Advertising, spanning driver onboarding, ML model hosting, mobile search, and iOS advertising SDKs. I led architecture for a multi-country driver onboarding workflow using AWS Step Functions and DynamoDB for idempotent state tracking, and I automated CI/CD security patching to reduce deployment cycles from weeks to under 2 days.
I also owned a federated internal platform for sustainability teams, standardized guided CI/CD workflows, and enforced least-privilege IAM and secrets management to drive cross-org AppSec resolution. In parallel, I scaled eligibility APIs to 5,000–10,000 TPS and modernized Prime Now iOS modules from Objective-C to Swift to reduce crashes below 1% after migration.
