What I'm looking for

I'm looking for a remote, hybrid, or location-flexible role where I can build scalable backend and full-stack products, own services through production, and collaborate with product, design, QA, DevOps, and cloud teams.

I'm currently modernizing legacy systems at Clinical Reference Laboratory into Java microservices, reducing critical-service latency by approximately 85% and improving API throughput by 22%. I build secure Spring Boot REST APIs, design fault-tolerant service workflows, and migrate containerized workloads to GCP Cloud Run.

Previously, I built high-volume FinTech workflows at PayPal and modernized enterprise applications at Optum Global Solutions using React, Java, Spring Boot, Kafka, PostgreSQL, and MongoDB. I enjoy owning services through production, improving performance and reliability, and guiding teams through architecture decisions, code reviews, and release delivery.
