Core modules compiled from production systems

Ordering Management System (OMS)

DEPLOYED Java EE Oracle DB Microservices

PROBLEM

Telecom ordering and invoicing workflows required modernization with improved scalability, faster deployment cycles, and better maintainability in enterprise environment.

ARCHITECTURE

  • Java EE microservices for ordering, charging, and invoicing
  • RESTful APIs for inter-service communication
  • Oracle Database for transactional consistency
  • Change Request (CR) system for feature deployment

IMPACT

40% Manual Effort Reduction Enterprise Scalability 24/7 Reliability

Cloud Migration - Amdocs Billing

COMPLETED AWS ECS/EKS Python

PROBLEM

On-premises billing infrastructure lacked elasticity, had high operational overhead, and couldn't scale during peak telecom traffic periods.

ARCHITECTURE

  • AWS ECS/EKS orchestration for containerized workloads
  • CloudFormation for Infrastructure-as-Code
  • Python automation for deployment pipelines
  • Multi-region failover strategy

IMPACT

80% Cost Optimization Auto-scaling Enabled 99.95% Uptime

End-to-End Automation Engine

ACTIVE Python Shell Jenkins

PROBLEM

Repetitive manual tasks in CI/CD pipelines consumed 10+ hours weekly, creating deployment bottlenecks and increasing human error risk.

ARCHITECTURE

  • Python scripts for business process automation
  • Shell scripting for system-level operations
  • Jenkins job orchestration and scheduling
  • Idempotent operations for reliability

IMPACT

30% Deployment Efficiency Gain Zero Manual Touchpoints 10hrs/week Saved

System Monitoring & Diagnostics

ACTIVE Kibana Elasticsearch Diameter Protocol

PROBLEM

Undetected Diameter protocol failures cascaded into customer-facing incidents, with no real-time visibility into system health.

ARCHITECTURE

  • Elastic Stack (Kibana/Elasticsearch) for log aggregation
  • Real-time alerting for protocol anomalies
  • Custom dashboards for system observability
  • Grafana integration for metrics visualization

IMPACT

20% Reliability Improvement MTTR Reduced 70% Proactive Detection

Django + Firebase Web Platform

RELEASED Python Django Firebase

PROBLEM

Legacy billing platform needed modern web interface with real-time data synchronization and mobile-first design.

ARCHITECTURE

  • Django ORM for data abstraction
  • Firebase Realtime Database for sync
  • AWS EC2 deployment with auto-scaling
  • RESTful API layer

IMPACT

Modern UX Delivered Real-time Sync Responsive Design

Kubernetes Cluster Operations

DEPLOYED Kubernetes Docker Openet

PROBLEM

Microservices needed container orchestration with zero-downtime deployments, auto-healing, and efficient resource utilization.

ARCHITECTURE

  • Kubernetes cluster management for Openet services
  • Docker containerization for application portability
  • YAML-based configuration management
  • Health checks and auto-restart policies

IMPACT

Zero-downtime Deployments Self-healing Clusters Resource Efficiency
