Visual documentation is crucial for understanding complex systems. This collection showcases architectural diagrams from real consulting projects, demonstrating different visualization techniques and abstraction levels.

System Architecture Diagrams

E-commerce Platform Architecture

Project: Microservices Migration
Scale: 10M+ users, 50+ services
Technology: Node.js, React, PostgreSQL, Redis, Kubernetes

Key Design Decisions:

• API Gateway: Single entry point for all client requests
• Service Isolation: Each service owns its data and business logic
• Caching Strategy: Redis for session data and frequently accessed content
• Search: Elasticsearch for product catalog search and analytics

FinTech Payment Processing System

Project: Event-Driven Financial Platform
Compliance: PCI DSS, SOX
Technology: Java, Spring Boot, Apache Kafka, PostgreSQL

Architecture Highlights:

• Event Sourcing: Complete audit trail for all financial transactions
• CQRS: Separate read/write models for optimal performance
• Event Streaming: Real-time processing with Apache Kafka
• Security: Vault for secrets management, comprehensive audit logging

Multi-Tenant SaaS Platform

Project: B2B Analytics Platform
Scale: 500+ tenants, 1TB+ data
Technology: Python, Django, PostgreSQL, Celery, Redis

Multi-Tenancy Strategy:

• Schema-per-Tenant: Strong data isolation using PostgreSQL schemas
• Shared Infrastructure: Cost-effective resource utilization
• Tenant Routing: Dynamic routing based on subdomain/headers
• Background Processing: Tenant-aware job processing with Celery

Data Flow Diagrams

Real-Time Analytics Pipeline

Project: IoT Data Processing Platform
Volume: 1M+ events/second
Technology: Apache Kafka, Apache Flink, ClickHouse

Data Synchronization Flow

Project: Multi-System Integration
Pattern: Event-Driven Synchronization
Technology: Apache Kafka, Debezium, PostgreSQL

Deployment Diagrams

Kubernetes Deployment Architecture

Project: Microservices Platform
Environment: Multi-region Kubernetes
Technology: Kubernetes, Istio, Prometheus

CI/CD Pipeline Architecture

Project: DevOps Transformation
Tools: GitLab CI, Docker, Kubernetes, ArgoCD

Security Architecture Diagrams

Zero Trust Network Architecture

Project: Enterprise Security Modernization
Framework: Zero Trust
Technology: Istio, OPA, HashiCorp Vault

Integration Patterns

Event-Driven Integration

Project: Enterprise System Integration
Pattern: Event Sourcing + CQRS
Technology: Apache Kafka, Event Store
