As per the policy, maximum base pay that anyone can get is of 10 months :)

Thanks me later Claude.ai

I highly recommend everyone reads this no matter your field or the stage of your career you are in. Felix has some great thoughts

Did a stupid amount of DSA in my first two years of college. Then I realised I didn’t actually like it that much, so I just… stopped. Tried backend instead. Turns out that’s the part of software that actually holds my attention. DSA got me through interviews. Building real systems is what made me want to stay in this field.

One prompt of Argon drained 25% of my weekly usage. Gemini 4 Carbon will most probably one shot my entire weekly limit 💀

Iom.lunamic.co had landed too

Backend development is simple, you just need to learn these... HTTP methods Status codes Request headers Response headers Authentication Authorization JWT tokens Session management Cookies OAuth 2.0 API design RESTful APIs GraphQL WebSockets Server-side rendering Database design SQL queries NoSQL databases Database indexing Query optimization ACID properties CAP theorem Normalization Denormalization ORM (Object-Relational Mapping) Connection pooling Transactions Migrations Seeding data Caching strategies Redis Memcached CDN integration Rate limiting Throttling API versioning Middleware Error handling Logging Monitoring Application performance monitoring (APM) Load balancing Horizontal scaling Vertical scaling Microservices architecture Monolithic architecture Service-oriented architecture (SOA) Message queues Pub/Sub patterns Event-driven architecture CQRS pattern Saga pattern API Gateway Service mesh Docker containers Kubernetes orchestration CI/CD pipelines Environment variables Configuration management Secrets management CORS (Cross-Origin Resource Sharing) CSRF protection XSS prevention SQL injection prevention Input validation Output sanitization Password hashing Bcrypt/Argon2 Salt and pepper Two-factor authentication (2FA) Single sign-on (SSO) RBAC (Role-Based Access Control) ABAC (Attribute-Based Access Control) File uploads Streaming data Pagination Filtering and sorting Full-text search Elasticsearch Background jobs Cron jobs Task scheduling Worker processes Async/await patterns Promises Callbacks Thread pools Process management Memory management Garbage collection Performance profiling Benchmarking Testing (unit, integration, E2E) Mocking and stubbing API docs (Swagger/OpenAPI) Postman/Insomnia Version control (Git) Code review practices Debugging techniques Production deployment strategies

After giving 10+ Backend interviews, I found only 20 topics you should really master - Backend Fundamentals: 1. How the Server Works (Request–Response Cycle) 2. REST API Design Principles 3. HTTP Methods & Status Codes 4. Middleware & Request Flow 5. Authentication vs Authorization Node.js & Backend Runtime: 6. Event Loop & Non-Blocking I/O 7. Async/Await & Promises 8. Error Handling & Global Error Middleware 9. Environment Variables & Config Management 10. Logging & Debugging Databases: 11. SQL vs NoSQL (When to Use What) 12. Database Schema Design 13. Indexing & Query Optimization 14. Transactions & ACID Properties 15. Relationships (1–1, 1–Many, Many–Many) Security & Scalability: 16. JWT, Sessions & Cookies 17. Password Hashing & Security Best Practices 18. Rate Limiting & Caching (Redis) 19. Scalability Concepts (Load Balancing, Horizontal Scaling) 20. API Versioning & Deployment Basics If you master these, most backend interviews become predictable 🚀

It'll be a good deal :) Let's Close this !!

Back to Twitter After a Week :)
