Interfacing & Integration
Designing and hardening industrial data interchange: OPC UA, message queues (MQTT / Kafka), REST/GraphQL APIs, file drops, secure tunneling and event driven pipelines bridging OT and IT layers.
Emphasis on schema governance, idempotent ingestion, buffering/backpressure strategies, replay diagnostics and cyber hardening (least privilege, cert rotation, network zoning, anomaly detection hooks).
