At Endava, I contributed to the DCTX Backend API and Back Office, connecting operator workflows with services for sports data, schedules, ingestion, payments, and customer records. I added management workflows for schools, teams, rosters, seasons, and schedules, and expanded fan notifications.
On Endava’s Benchmarking Studies, I developed Java backend features for the Hackett Advisory application. I implemented a JUnit testing framework that reduced post-release hotfixes by 60% and led the migration from monolithic Java 8 to Java 11 microservices with Spring Boot.
For the Oil & Gas SCADA system, I developed Java HMI modules and a JNI layer integrating Java with native C/C++ systems. The deployment across multiple sites had zero critical incidents.
As a Java Freelancer, I delivered a Spring Boot code-generation platform that generated applications with controllers, services, and JPA data-access layers, reducing Java application development time by 70%.
