Creating and building amazing technology with an amazing team at an amazing company!

Re-architecting backend systems written in Java, powered by Spring Boot with a React frontend, to build next generation developer portals and a workflow processing engine that automates and facilitates any activity or process across the business in order to keep creative teams on track to deliver amazing results when it matters! * Using Spring Security along with a custom SPI, we can interface with any security providers [ Azure AD/LDAP, OAuth, ... ] and always maintain a secure posture * Using Spring Data JPA/Hibernate, we can persist information and fine-tune queries used to access data in any RDBDS; presently using Postgres/H2 * Using Spring Data Redis, we can cache any requests/responses to further reduce latency and increase throughput * Using Eclipse jgit, we can initiate actions in GitHub to coordinate product deployments and delivery across environments * Using Atlassian Jira REST APIs, we create & modify tickets to facilitate coordination with external teams * Using OpenRewrite, we can help developers upgrade systems using known/proven recipes * Creating Flows, we can onboard developers joining new teams or products in a matter of minutes, rather than days. I was tasked with all aspects of the platform design and system software architecture/integration.
