Message

At CLOUDPAY, I design and maintain Java microservices while driving the migration of core monolithic services to a decoupled, cloud-native architecture. I’ve built Apache Kafka event-driven pipelines and improved a REST API platform using Saga Orchestration and CQRS.

At STACKS, I architected Java and Spring Boot microservice backends for healthcare platforms and established CI/CD pipelines and automated testing frameworks. Earlier, I engineered distributed backends at ERNI CONSULTING and advised enterprise stakeholders on modernizing legacy systems.
