- Primarily focused on a web SPA used by health-care field agents to manage their clients and book of business. Built new and enhanced existing modules for Angular front-end (deployed as Docker images in Azure App Services) as well as Java/Spring Boot microservices (exposed as RESTful APIs), deployed as Docker images to Azure Kubernetes Service (AKS). This work was heavily data-driven, using Liquibase to manage business-domain schemas in Microsoft SQL Server, as well as Apache Kafka to synchronize data among the business domains and to notify downstream services of CRUD operations.- To improve performance and to help alleviate load on the databases, used Azure Cache for Redis cluster with several nodes which functioned as a server-side cache.- Mentored junior engineers to implement best practices for code review and testing.- Initiated effort to standardize Angular and Java components for search, sort, and filter.- Orchestrated complex infrastructure environments in Azure using data-driven Terraform templates to allow code reuse across all environments.
