Meet Mai-san.. A offline Ai Assistance with raspberry pi…. For know we are running ollama and qwen 2.0.5b model which is doing a simple linear search algorithm in Java it’s a team work project … (The assistant can also speak. I am editing the video soon )

backend isn’t “hard” you’re just overcomplicating it. learn these once, and you can build anything: • HTTP — how the internet actually talks • databases — where your product really lives • caching — stop hitting your DB like a maniac • auth — keep idiots out of your system

Cloudflare is worth billions????? BILLIONS???????????? for literally…… standing in front of websites????

Great resources for learning backend & systems: - Designing Data-Intensive Applications - Beej’s Guides - CMU Database Group - Hacker News - Writing an OS in Rust - ByteByteGo - Computer Systems: A Programmer’s Perspective - Julia Evans’ Blog - Strange Loop conference videos -

As a developer, you should be able to clearly explain at least 10 of these: - Load Balancer - API Gateway - Reverse Proxy - Throttling - Rate Limiting - Idempotency - Pagination - Cache Stampede - gRPC - GraphQL - Webhooks - OAuth - JWT - Cache Invalidation - Query Optimization

Step-1: Learn JavaScript (not just syntax, understand the weird parts) Step-2: Master closures, prototypes & the event loop Step-3: Understand async deeply (promises, async/await, microtasks vs macrotasks) Step-4: Build real UIs with React (state, hooks, rendering behavior)

Bro is back after a long time, support him

As a backend developer, you should understand these database fundamentals: - Indexing - Joins - Transactions - Isolation Levels - Deadlocks - Replication - Partitioning - Query Planner - Normalization - Denormalization - Write Amplification - Read Optimization Databases decide
