Strangler Pattern Migration from Legacy BSS to Modern OSS
Challenge
Big-bang migration risk with 200+ legacy integrations, point-to-point spaghetti architecture, and a strict zero downtime requirement for order fulfillment.
Architecture Approach
Implemented a phased Strangler Fig Pattern migration with an API Gateway layer (TMF622, TMF641), dual-run validation using Kafka event duplication, and incremental component cutover aligned to ODA standards.

CSP MODERNIZATION
Multi-vendor Inventory Trust & Reconciliation
Challenge
Fragmented inventory across 7 active sources, 3 passive sources, and service layer with 35% data mismatch causing failed provisioning and billing disputes.
Architecture Approach
Implemented TM Forum Resource Inventory (TMF639) aligned hub with Neo4j graph backend, automated reconciliation engine using rule-based + Flink stream processing, and topology validation framework.

CSP MODERNIZATION
Topology-Aware Assurance Modernization
Challenge
Alert storms averaging 12,000+ alarms/day with 4.5 hour MTTR due to poor correlation, no topology context, and siloed domain monitoring.
Architecture Approach
Built topology-aware correlation engine using Neo4j graph-based impact analysis, implemented Flink-based noise reduction stream processing (95% accuracy), and automated RCA workflows with evidence-linked outputs.
