• Built multiple microservices using Java Spring Boot, including high-impact services that
• simplified critical workflows and significantly reduced Rx order cancellations—such as failed payment
• handling for mail-order pharmacy, patient data creation across multiple entities with
• matching logic, socket-based communication interfaces, and drug-type–driven workflow
• processing.
• Reduced 5–10 second workflows to sub-second by optimizing Java 8, Spring Boot, Hibernate,
• and PL/SQL microservices by tuning queries, correcting entity relationships, JVM profili
• ng, multithreading and implementing Ehcache-based strategies.
• Redesigned secure, versioned REST APIs including one central API that handled requests from
• over 20 servers and 3 specialized APIs for processing patient orders, documented and enforced API
• contracts using Swagger/OpenAPI and JAX-RS with strong validation, pagination, and error
• handling. Optimized data-access layers and schemas across Oracle Relational Data(RDBMS)
• systems.
• Continuously developed, tested, and improved code quality, including migrating the project
• from JUnit 4 to JUnit 5 and writing comprehensive test suites.
