Select any project to explore its full source code across TypeScript, HTML, SCSS, and Configs.
Module 1: Network Inventory REST API
Build an enterprise-grade Network Inventory REST API using Node.js, Express, and TypeScript with layered architecture, DTO validation, and structured error handling.
Module 2: MongoDB Optimization & Indexing Lab
Migrate device inventory to MongoDB, design compound & partial indexes, write aggregation pipelines, and diagnose slow queries with explain("executionStats").
Module 3: Angular 18+ Network Operations Dashboard
Architect a modern Angular 18+ UI with Standalone Components, fine-grained Signals, RxJS streams, Typed Reactive Forms, and OnPush Change Detection.
Module 4: Enterprise Authentication & Role-Based Access Control (RBAC)
Implement secure JWT authentication, rotating refresh tokens in httpOnly cookies, hierarchical RBAC permissions, Route Guards, and OWASP security hardening.
Module 5: Asynchronous Automation Job Engine
Build an asynchronous background execution engine returning 202 Accepted, worker task queues, exponential backoff retries, and job state machines.
Module 6: Itential IAP Simulator & REST Integration
Build an Itential Automation Platform (IAP) REST simulator and implement a decoupled Adapter/Provider integration architecture.
Module 7: Telecom Backhaul Circuit Management
Build an enterprise Backhaul Circuit management system with circuit topology mapping, provisioning state machine, and automated audit trails.
Module 8: Production Incident Troubleshooting & RCA Lab
Diagnose real production incident simulations (7-second API latency spike, event loop blocking, memory leaks) and author executive Root Cause Analysis (RCA) reports.
Module 9: Enterprise Testing Pyramid
Master the testing pyramid: Jest unit testing, Supertest API integration testing, Angular Component TestBed, and Playwright/Cypress E2E automation.
Module 10: Production Hardening & Resilience Engineering
Harden Node.js and MongoDB for production: Helmet, rate limiting, connection pooling, Redis caching, Gzip compression, and graceful shutdowns.
Module 11: Enterprise Scaling — Modular Monolith to Event-Driven Microservices
Decompose monolithic services into an event-driven architecture using Kafka, Docker containerization, Kubernetes manifests, and an API Gateway.
Module 12: Capstone — Network Automation Command Center
Synthesize the entire 12-week curriculum into a unified, production-ready enterprise Network Operations & Automation Portal with real-time telemetry.
