Senior🎓
Top SchoolJohn A is a Senior Solutions Engineer based in Ottawa with over two decades of hands-on expertise in enterprise integration, now focused on helping customers shift from point-to-point middleware to real-time, event-driven architectures using Solace and Advanced Event Mesh. He brings deep specialization in SAP integration and IBM middleware (MQ, IIB/WMB) across insurance, rail, banking, retail, media, government, pharma and chemical sectors, and has led technically complex migrations that saved clients substantial licensing and operational costs. Known for pragmatic designs, he has implemented mission-critical MQ infrastructures for Positive Train Control compliance and built observability and cloud connectivity solutions that leverage existing monitoring platforms. Equally comfortable in technical delivery and stakeholder-facing architecture workshops, he has a long track record of operational reliability, disaster recovery planning, and mentoring teams. Although retired from public code contributions, his breadth of certifications and repeated engagements with major enterprises reflect a practitioner who turns legacy risk into resilient, real-time integration landscapes.
