VIVE Link
viveapp.com
VIVE Link is a platform that helps people shape their future financially, regardless of their knowledge, experience, income or lifestyle. The backend is built as Spring Boot microservices (Java 11/17, Gradle) that communicate mostly synchronously, running on Docker and Kubernetes behind a Kong Ingress Controller API gateway, with Jaeger tracing, Dropwizard metrics in AWS CloudWatch, AWS pipelines using blue-green deployment, and OpenSearch-based BI. I was part of the Front Office team of around 10 people from December 2020 to the present.
