• Golang and Backend in Go: Concurrency, error handling, RESTful APIs, auth in Go

## API Design & Architecture
• REST APIs: Designing endpoints, HTTP methods, status codes, API versioning (Twitter App Backend)
• Modern Communication: gRPC (Protocol buffers) & GraphQL (Apollo Server, resolvers, schema)
• MVC Architectures: Service layer, repository layer, config, seeders, controllers, jobs/consumers
• Microservices, Monolith & Monorepo: Sync/async interservice communication, transactions, Turborepo

## Validation, Safety & Tooling
• Writing Validations using Zod: Schema validation, request body validation
• Typesafe Backends with tRPC: RPC frameworks, building URL shortener with tRPC
• File Uploads: AWS S3, Presigned URLs, Multer integration
• Websockets & Socket.IO: Real-time communication, rooms, namespaces, Server-Sent Events (SSE)

## Databases & Scaling
• Basic Databases: MySQL & MongoDB (CRUD, Normalisation, MongoDB Atlas)
• Indexing in Databases: Types of indexes, query performance optimization
• Scaling DBs: Partitioning, Replication (Master-slave, Multi-master), Sharding
• Schema Designing: Complex DB schema for Twitter & Airbnb
• Advanced Transactions: ACID properties, isolation levels, optimistic/pessimistic concurrency
• Advanced MongoDB: Backups, sharding, transactions, aggregation framework
• ORMs and ODMs: Mongoose (MongoDB), Prisma ORM with TS support

## Auth, Caching & Cloud
• Authentication & Authorization: JWT, Token/Session-based auth, RBAC, OAuth 2.0
• REDIS: Caching, BullMQ queues, Geospatial indexing (Uber use-case)
• Scaling apps with AWS Cloud: EC2, ELB, Auto Scaling, Vertical/Horizontal scaling
• Scaling & Deploying Node Apps: Render, AWS, PM2, multi-core scaling
• Databases in AWS Cloud: RDS, DocumentDB, DynamoDB, S3, Redshift
• AWS Lambda & IAM: Serverless functions, permissions, ELB integration

## System Design & DevOps
• Basics of System Design: Load balancers (L4/L7), Caching, CAP Theorem, Consistent hashing, SQL vs NoSQL
• Containers & Docker: Images, containers, Docker CLI, volumes, networking
• DevOps for Backend Engineers: CI/CD (GitHub Actions, Jenkins), secrets management, Kubernetes orchestration, Prometheus & Grafana monitoring
• Kafka and RabbitMQ: Message queues, pub-sub patterns, dead letter queues, scaling high throughput
• Idempotent APIs, API Gateways & Proxies: NGINX, Kong, rate limiting, circuit breaking, CORS
• Testing: Unit testing (Jest), TDD, mocking (Sinon), integration testing (Supertest), performance testing (K6, Postman)
• Monitoring and Observability: Logging practices, Azure Cosmos, application monitoring

## 🧩 Real-World Projects
• Codesandbox Clone: In-browser code editor, containerized React execution, Websockets
