Software Developer at Lufthansa Industry Solutions

June 1, 2024 - June 1, 2026

Built and maintained event-driven microservices using Quarkus and Azure Event Hubs to enable asynchronous transaction processing and improve system responsiveness. Led migration of legacy JBOSS monoliths to containerized Spring Boot services, reducing deployment time (35–40 minutes to 20 minutes) via build-once, promote-across environments, consistent container image tagging, and zero-downtime production releases using OpenShift and Helm. Optimized critical APIs with Caffeine in-memory caching and SQL query tuning, reducing P95 latency (1.2s to 350ms) and eliminating timeout errors during peak periods. Architected an exactly-once Kafka pipeline using the Outbox pattern to eliminate data consistency incidents and used CAS operations to prevent race conditions and data corruption. Built end-to-end CI/CD pipelines with Jenkins and Docker, integrated Snyk security scanning and Prometheus monitoring, and deployed on OpenShift running on Azure.
