System Design

Architecture Patterns in Practice

Proven patterns and system designs implemented in production projects.

Modular Monoliths

Domain-driven modular services built with NestJS. Clear separation of concerns with controllers, services, and repositories for maintainability.

Implemented in: DA-Mall Marketplace Backend

NestJSDomain-DrivenClean Architecture

Hybrid AI Microservices

Separation of heavy ML inference pipelines from core business APIs. Fast API gateways orchestrate lightweight web services and asynchronous Python workers.

Implemented in: Email EU Graph & VisualMind Search

FastAPI GatewayMicroservicesAsynchronous Queues

Real-time Event Systems

WebSocket-based bidirectional communication architectures with Socket.io for live chat, telemetry, and notifications.

Implemented in: HealSeek & Edu+ Platforms

Vector Search & Embeddings Layer

Sub-50ms approximate nearest neighbor (ANN) retrieval indexes with FAISS and CLIP embeddings connected to caching layers.

Implemented in: VisualMind & MentorAI RAG

Philosophy

Engineering Principles

Security by Design

JWT authentication, input sanitation, rate limiting, and strict CORS policies.

Performance Optimization

Redis caching, query indexing, edge asset optimization, and minimal bundle footprints.

Clean, Typed Code

Strong TypeScript typing, SOLID principles, DRY abstractions, and comprehensive docs.

Containerization & CI/CD

Docker multi-stage builds, predictable environments, and automated testing.

Observability & Logging

Structured logging, healthcheck endpoints, and proactive error tracing.

Scalable Database Design

Normalized schemas, indexing strategies, connection pooling, and replication.
