What I'm looking for

I'm looking to build scalable cloud platforms and production AI solutions where Java, distributed systems, RAG, and cloud automation create measurable business impact.

I modernized enterprise platforms at Upbound Group, eBay, Diebold Nixdorf, and Collins Aerospace, building cloud-native microservices, high-throughput APIs, and responsive web applications.

At Upbound Group, I led backend architecture for a legacy-to-cloud transformation using Java 17, Spring Boot, AWS, PostgreSQL, Redis, and DynamoDB. I reduced API latency by 35%, improved database throughput by 40%, and built a Lambda and Kinesis pipeline handling more than 500K daily events at sub-second latency.

At eBay, I developed Angular SPAs and Spring Boot microservices for checkout and inventory workflows serving millions of users during peak and Black Friday loads with zero downtime. I also accelerated AKS deployments by 50% with Helm-based CI/CD and strengthened event-driven order processing with RabbitMQ.

I'm extending my backend and cloud engineering work through production AI applications, including RAG-powered marketing generation, customer personalization, and a GreenOps AI agent that identifies cloud cost and carbon optimization opportunities with human approval.
