• Solid understanding of domain driven design utilizing object-oriented programming principles, secure coding, and best engineering practices

• Hands-on experience designing, developing, and operating event-driven systems using Apache Kafka.

• Design & execute performance tests (load, stress, soak, spike, capacity) using Apache JMeter; build reusable test plans and data strategies.

• Instrument and analyze end-to-end system performance with Dynatrace (or similar APM)—trace hotspots across services, JVM/CLR, DB, caches, and external dependencies.

• Engineer for scalability & resiliency—profile bottlenecks, optimize code paths, tune JVM/GC, threads, DB queries, connection pools, caches, and message brokers.
