Engineering Outcomes That Hold Up in Production

Challenge

A growing operator was hitting capacity ceilings on a legacy AAA stack — authentication latency was climbing during peak hours and horizontal growth required disruptive vendor upgrades.

Approach

Re-platformed onto a horizontally scalable RADIUS / Diameter core with active-active deployments, externalized session state, and protocol-aware load balancing. Hardened observability with structured logs, metrics, and traces.

Outcomes

• Sub-millisecond p95 authentication latency under peak load
• Linear horizontal scale-out with zero protocol changes for clients
• End-to-end auditability of every authentication and accounting event

Challenge

Disconnected billing, provisioning, and customer-care systems were causing revenue leakage, slow dispute resolution, and friction across the subscriber journey.

Approach

Unified subscriber lifecycle, billing, charging, and customer operations into a single, workflow-driven platform with a clean audit trail and well-defined integration points to network and payment systems.

Outcomes

• Single 360° subscriber view across billing, support, and operations
• Materially reduced revenue leakage and dispute cycle time
• Automated dunning, collections, and partial-payment handling

Challenge

Event volumes were growing faster than the existing mediation pipeline could keep up with — back-pressure, lost records, and downstream reconciliation pain were becoming routine.

Approach

Re-engineered the mediation pipeline with bounded queues, idempotent processing, replayable streams, and protocol-aware enrichment. Added end-to-end tracing of every record from collection through downstream delivery.

Outcomes

• Multi-fold higher CDR throughput with guaranteed delivery semantics
• Replayable, traceable pipelines with no record loss under failure
• Cleaner downstream feeds for billing, fraud, and analytics consumers

Challenge

A core enterprise workload was suffering from slow page loads, expensive analytical queries, and rising infrastructure costs on legacy infrastructure.

Approach

Migrated workloads to AWS with a well-architected landing zone. Ran a focused database engineering cycle covering schema review, index strategy, query rewrites, partitioning, and connection-pool tuning.

Outcomes

• Significant reduction in p95 response time across key user journeys
• Lower infrastructure spend through right-sizing and managed services
• Predictable performance for OLTP and analytical workloads alike
