Own design and implementation of offline-first multi-tier synchronization for a global QSR POS: CRDT-based conflict resolution (Automerge/Ditto), event sourcing, CQRS and saga patterns for order/payment flows, real-time pub/sub/WebSockets, and PostgreSQL cloud data modeling with reconciliation between device, edge, and cloud stores.

Own offline-first synchronization for a global QSR POS: design multi-tier sync across device, restaurant edge, and cloud. Implement CRDT-based conflict resolution (Automerge/Ditto), event sourcing, CQRS, and saga patterns for order/payment flows. Use real-time pub/sub or WebSockets, and model PostgreSQL cloud data layer with reconciliation against local and edge stores.

Design and implement offline-first, multi-tier data synchronization for a global QSR POS: CRDT-based conflict resolution, event sourcing/CQRS/saga patterns, real-time pub/sub or WebSockets, and PostgreSQL-backed reconciliation between device, edge, and cloud stores.

Lead design and implementation of offline-first multi-tier synchronization for a global QSR POS: CRDT-based conflict resolution, event sourcing, CQRS and saga patterns, real-time pub/sub/WebSockets, and PostgreSQL data modeling and reconciliation between device, edge, and cloud.

Design and implement offline-first, multi-tier synchronization across device, edge, and cloud for a QSR POS platform using CRDT-based frameworks (Automerge/Ditto). Build conflict-resolution, event sourcing, CQRS, and saga patterns for orders/payments, use real-time pub/sub/WebSockets, and model/reconcile PostgreSQL cloud data with local and edge stores.

Design and implement multi-tier offline-first synchronization across device, edge, and cloud for a QSR POS. Build CRDT-based conflict resolution (Automerge/Ditto), apply event sourcing, CQRS and saga patterns, use WebSockets/pub-sub for real-time state, and model PostgreSQL cloud layer with reconciliation strategies.

Design and implement multi-tier offline-first synchronization for a global POS platform using CRDT-based frameworks (Automerge/Ditto), event sourcing, CQRS, saga patterns, real-time pub/sub/WebSockets, and PostgreSQL-backed reconciliation across device, edge, and cloud.

Design, build, and maintain backend integrations between a public safety platform and third-party systems using Java/Spring Boot. Develop REST, SOAP, and GraphQL integrations, improve RMS/CAD/Booking data pipelines, write tests, debug production issues, document solutions, and collaborate across teams to deliver secure, scalable cloud-based integration workflows.

Design and implement offline-first multi-tier data synchronization for a global POS, using CRDT-based frameworks, event sourcing, CQRS, sagas, real-time pub/sub/WebSockets, and PostgreSQL-backed reconciliation between device, edge, and cloud.

Lead design and implementation of offline-first, multi-tier data synchronization for a global QSR POS. Implement CRDT-based conflict resolution (Automerge/Ditto), event sourcing, CQRS, and saga patterns; use real-time pub/sub/WebSockets; model cloud PostgreSQL and reconciliation between device, edge, and cloud stores.
