?? Roadmap to Learning System Design for Mobile App Development ??

Since you're a Flutter developer with 3 years of experience, this roadmap will focus on system design tailored for mobile apps, covering backend architecture, scalability, security, and performance.

?? 1. Fundamentals of System Design (1-2 Weeks)

? What is System Design?

  • Understanding monolithic vs. microservices architecture
  • Basics of scalability, latency, throughput, and availability

? Key Concepts:

  • Load Balancers, API Gateway
  • Caching (Redis, CDN)
  • Databases (SQL vs. NoSQL)
  • Authentication & Security (OAuth, JWT)

? Resources:

?? 2. Mobile App Backend Architecture (3-4 Weeks)

? Backend for Mobile Apps

  • Firebase vs. Custom Backend (Node.js, FastAPI, Django)
  • REST API vs. GraphQL
  • WebSockets for real-time features

? Database Design

  • SQL (PostgreSQL, MySQL) for structured data
  • NoSQL (MongoDB, Firestore, DynamoDB) for flexibility
  • Sharding & Replication for scalability

? Hands-on Project:

  • Build a simple API for a mobile app (e.g., user authentication, CRUD operations)

? Resources:

?? 3. Advanced System Design (4-6 Weeks)

? High Availability & Scalability

  • Load Balancing (NGINX, AWS ALB)
  • Horizontal & Vertical Scaling (Kubernetes, Auto-Scaling)
  • Event-Driven Architecture (Kafka, RabbitMQ)

? Caching & Optimization

  • Redis / Memcached for caching API responses
  • CDN (Cloudflare, AWS CloudFront) for faster content delivery

? Security Best Practices

  • OAuth2, JWT, Role-Based Access Control (RBAC)
  • Rate Limiting & DDoS Protection

? Hands-on Project:

  • Optimize an API with caching & load balancing

? Resources:

?? 4. Practical System Design Interviews (2-4 Weeks)

? Learn System Design Patterns

  • Microservices vs. Monolith
  • Event-Driven Design
  • CQRS & Event Sourcing

? Practice System Design Case Studies

  • Design a Scalable Chat App
  • Build a Video Streaming Backend
  • Optimize an E-commerce API

? Resources:

  • Grokking the System Design Interview
  • Leetcode Discuss: System Design Topics

?? Summary: 4-Step Roadmap to System Design

1?? Learn Fundamentals → Basic concepts of system design 2?? Build a Backend for Mobile Apps → REST APIs, Databases, Authentication 3?? Master Advanced Topics → Scalability, Caching, Load Balancing 4?? Practice Real-World System Design → Case studies & interviews
