## About

```text
At Walmart, I design Java 17 and Spring Boot services for accounting, order, and operational ticketing workflows, increasing application throughput by 30%. I also developed enterprise AI search services with FastAPI, OpenAI APIs, embeddings, and RAG to support natural-language search across operational documents and knowledge bases.

At Walmart, I architect Kafka-based event processing for order, payment, and notification workflows, and optimize SQL across Oracle and PostgreSQL. I also build React and TypeScript interfaces and maintain containerized services on Azure Kubernetes Service.

At Oracle, I developed Java and Spring Boot applications and REST APIs serving enterprise users, improving API latency by 30%. I also developed Python and FastAPI AI microservices for document classification, semantic search, and LLM-powered summarization.

At LTI Mindtree, I led development of a Kafka and AWS-based notification platform and delivered a unified payment gateway API supporting 1M+ daily transactions. Earlier, at Wells Fargo, I built Java and Spring Boot services for financial transactions and reduced inter-service latency by replacing REST with gRPC.
