• Advance N4 data models, APIs, and services, powering automation, inventory control, and seamless integrations. 

Distributed Systems Mastery 

• Implement and maintain both traditional JEE stack, and event-driven, microservices-based architectures using Kafka and ActiveMQ (JMS). 
• Ensure reliability, fault-tolerance, and message integrity in global deployments. 

Complex Problem Solving 

• Lead “war room” sessions to address distributed system failures, bottlenecks, deadlocks, and memory leaks using advanced debugging and profiling methods. 

Database Design, Administration & ORM
