Project Casper

Overview

Led the critical transformation of the monolithic TC+ platform into microservices architecture. Project Casper focused on segregating the integration layer from the main platform, internal tools, and other components, creating a high-performance, independently deployable microservice ecosystem.

The Challenge

The monolithic TC+ platform faced scaling and deployment challenges:

• 15+ hour deployment cycles affecting all system components
• Integration changes impacting the entire platform stability
• Unable to scale integration APIs independently during peak loads
• Lack of dedicated monitoring for critical integration services

My Role & Solution

• Architected decoupling of microservices communication layer
• Built custom lightweight PHP framework optimized for low latency
• Achieved 100% code coverage with test-driven development
• Implemented comprehensive monitoring with Datadog and Site24x7
• Led the segregation of integration services from monolithic platform

Technical Implementation

Microservice Architecture

• Main TC+ Platform: Core assessment functionality
• Integration Service (Casper): All ATS integration APIs and workflows
• Internal Tools: Admin and management interfaces
• Custom PHP Framework: Lightweight, optimized for response time
• Communication Layer: Decoupled service-to-service messaging

Performance Optimization

• Custom PHP framework focused on minimal latency
• MongoDB for flexible data storage and high-speed operations
• Elasticsearch for comprehensive auditing and log analysis
• Optimized infrastructure for maximum throughput
• Intelligent caching strategies at multiple layers

Monitoring & Observability

• Datadog: Real-time metrics and performance monitoring
• Site24x7: 24/7 alerting with custom thresholds
• Elasticsearch: Centralized logging and auditing
• Custom Metrics: Business and technical KPIs tracking
• Alerting: Multi-channel notifications for critical events

Results & Impact

Key Achievements

• Transformed 15+ hour deployments to under 1 hour (93% reduction)
• Achieved 100% test coverage reducing production bugs by 75%
• Improved integration performance by 71% through optimized architecture
• 90% reduction in sprint cycle times through efficient deployment
• Zero-downtime deployments with independent service scaling
• Comprehensive monitoring ensuring proactive issue resolution

Development Practices

• Test-Driven Development: 100% code coverage requirement
• CI/CD Pipeline: Automated testing and deployment
• Code Quality: Strict standards and peer review process
• Documentation: Comprehensive API and service documentation
• Performance Testing: Load testing for every release
