Strategic Technical Leadership

• End-to-End Traceability:Lead the team in tracing transaction flows from the API Gateway (API Connect) through the Enterprise Service Bus (ACE) to the backend Microservices (Spring Boot).
• Root Cause Analysis (RCA):Spearhead deep-dive investigations into middleware failures, such as message losses in MQ, synchronization errors in ACE, or JVM crashes in Spring Boot.
• Platform Governance:Oversee the stability of integration components running onRed Hat OpenShift, ensuring optimal resource (CPU/Memory) allocation and pod scaling.
• Security Enforcement:Manage and troubleshoot security protocols, including Mutual TLS (mTLS), OAuth2, and JWE/JWS within the integration layer.

Detailed Technical Responsibilities

A. IBM Cloud Pak for Integration (CP4I)

• App Connect Enterprise (ACE):Troubleshoot message flows, ESQL logic errors, and adapter connectivity issues (SAP, Database, File).
• IBM MQ:Manage queue managers, resolve channel retries, and investigate dead-letter queues or message persistence issues.
• API Connect:Resolve issues related to API definitions, security policies, and Gateway (DataPower) latency.

B. Backend Microservices (Spring Boot)

• Performance Tuning:Analyze JVM thread dumps and heap dumps to resolve memory leaks or high CPU utilization in microservices.
• Connectivity Debugging:Troubleshoot Spring Boot integration with databases (JPA/Hibernate) and external messaging systems (JMS/Kafka).
• Log Aggregation:Utilize ELK/Splunk to correlate logs across multiple microservices to identify points of failure in a distributed architecture.

Technical Skill Set

• Integration Platforms:Mastery ofIBM CP4I(specifically ACE, MQ, and API Connect).
• Development Frameworks:Advanced knowledge ofJava and Spring Boot(Spring Integration, Spring Cloud).
• Containerization:Expert-level proficiency inRed Hat OpenShiftand Kubernetes.
• Protocols & Standards:Expert understanding of REST, SOAP, JSON, XML, AMQP, and MQTT.
• Monitoring Tools:Hands-on experience withIBM Instana, Dynatrace, or Prometheus/Grafana.
