  • Improved alarm data retrieval by 40?50% via targeted PostgreSQL indexing, reducing real-time query latency for high-volume 5G device monitoring.
  • Cut large-dataset scan time by 35% with date-based table partitioning in PostgreSQL; scaled Cassandra for high-throughput telemetry across connected devices.
  • Slashed Cassandra storage overhead by 60%+ via 24-hour retention window for alarm data, maintaining full real-time visibility without over-provisioning.
  • Eliminated 90% of repetitive bulk-update effort via dynamic stored procedure for role-based API access control across all multi-tenant records.
