At Walmart Business, I built four reconciliation report APIs for Spend Analyzer and designed account consolidation so admins can see purchase history across merged organization accounts. I also co-built the Walmart Business Chatbot from demo to limited production, including a reorder tool that checks stock, delivery slots, and account spend limits.
At CVS Health Inc, I rebuilt a monolith as Spring Boot microservices with Redis caching, cutting latency from seconds to under 200 ms. I owned a formulary-alternative API and migrated four microservices from Java 8 through Java 17 to Java 21.
At PayPal, I built Spring Boot APIs for Braintree in-store payments, pay-later, pickup, and refunds, and wrote unit and end-to-end tests for payment and refund flows. I’ve also served on call and mentored new hires.
