WORK HISTORY
Java Developer @Verizon
Irving, TX, US
Engineered service resiliency by implementing Resilience4j circuit breakers, preventing cascading failures during downstream outages and maintaining 99.9% API availability. • Configured fallback mechanisms and retry policies for 9+ retail APIs, ensuring graceful degradation of services and a seamless user experience during intermittent network latency. • Developed 15+ retail APIs using Spring Boot; tuned Hibernate connection pools and utilized Java CompletableFuture for asynchronous request handling, reducing P95 API latency by 20%. • Decoupled high-traffic data flows via AWS SQS to buffer peak 5G traffic spikes, ensuring order persistence and eventual consistency during backend service downtime. • Automated GitLab CI/CD pipelines using Docker to containerize services, eliminating environment-specific bugs and reducing production deployment failure rates by 45%. • Built a suite of automated validation mocks to simulate external vendor responses, achieving 98%+ test coverage and catching edge-case null pointers before staging.
