- Assess the use of message queues (MQ):
- asynchronous communication patterns,
- queue configuration,
- message handling and error management,
- retry mechanisms and Dead Letter Queues (DLQ),
- delivery guarantees (e.g. at-least-once, exactly-once),
- queue throughput and impact on replication latency.
- Conduct or support performance and load testing aligned with real production data volumes.
- Analyze end-to-end processing times, system stability under load, and identify architectural bottlenecks.
- Monitor and assess CPU utilization (MSU) during peak data transfer periods.
- Identify optimization opportunities to reduce resource consumption, improve performance, and control costs.
- Prepare architecture review reports, findings, and recommendations for both technical and non-technical stakeholders.

- Experience with performance testing, scalability analysis, and non-functional requirements.
- Knowledge of high-availability and fault-tolerant architectures.
- Experience in banking or regulated environments is highly desirable.
- Ability to work effectively in hybrid delivery models (on-site and remote).
Language & Location Requirements
