(2023-11)

• Developed order orchestration microservices (Java 8, Spring Boot, JPA/Hibernate, Oracle DB) processing 10,000+ orders/day with 99.9% uptime on a platform serving 35M+ mobile subscribers.
• Created RESTful APIs for the complete order lifecycle (create, split, activate, fulfill, cancel) with idempotent endpoints, optimistic locking, and ACID transactional consistency across multiple entities.
• Constructed event-driven workflows using Apache Kafka (at-least-once delivery) and Flowable BPMN for stateful order orchestration across 5+ downstream services (activation, payment, shipping).
• Addressed P1 production incidents under SLA via systematic root cause analysis; fixed a timing-dependent state propagation bug blocking fulfillment for 500+ orders, attaining zero post-fix regressions.
• Reached 95% code coverage on core business logic with JUnit 5/Mockito tests covering happy-path, boundary, negative, idempotency, and timeout scenarios.
• Architected end-to-end test automation: REST Assured API contract tests + Selenium WebDriver UI regression + TestNG orchestration; reduced manual QA by 40%, boosted regression coverage by 60%.
• Built Jenkins CI/CD pipelines with Maven, Docker, and SonarQube quality gates; cut build-to-deploy cycle by 35% and lowered production incidents by 20% via rollback triggers.
• Conducted code reviews, spotted anti-patterns, and enforced standards via SonarQube and peer review checklists across 8-member onshore/offshore team.
• Collaborated in Agile/Scrum: sprint planning, backlog grooming, design reviews, and defect triage in JIRA and Confluence.
