March 1, 2022 - Present

Owned end-to-end features and technical components of the Promotion application with Loyalty integration using Next.js, PostgreSQL, Docker and AWS CDK (Fargate service, S3, RDS, ALB). Took ownership of frontend, backend, CI pipeline, automated test suites, and operations for Version 2 of the E-Store. Reduced worst-case load time from 15s to 3s by redesigning data flows and optimizing SQL queries, and by shifting compute-heavy logic to backend services. Led the first release of a suite of apps using React Native Expo, Apollo Client, Docker, and Jest. Resolved a production outage caused by high traffic and database connection pool exhaustion. Implemented API rate limiting on file upload endpoints to mitigate abuse and protect system stability.
