You call yourself a backend developer?
Let’s test something real.
How many of these can you actually explain without Googling?
1. Event-Driven Architecture
2. Saga Pattern
3. CQRS
4. Event Sourcing
5. Circuit Breaker Pattern
6. Distributed Tracing
7. CAP Theorem
8. Idempotency
9. Data Sharding
10. API Gateway
Because knowing syntax is easy.
Understanding how systems behave in production is what sets you apart.
Be honest, how many? 👇

@tanwaraakriti I never thought AI would become this much upgrade in just short period of time and replacing humans.

What’s the AI use case you were most sceptical about and that actually worked?
I’ll go first: automated document organisation. Thought it would be unreliable. Turns out the messier the folder, the more obvious the value.
Your turn.

@devXritesh google search engine uses inverted index data structure… for fast retrieval’s
English
As a developer,
Have you ever wondered :
You type just "how to" in Google search and it instantly shows full suggestions like "how to make money", "how to cook pasta" etc...
There are 8.5+ billion searches globally every day.
How is this autocomplete so fast?
English
@devXritesh Speed comes from smart data structures, not psychic powers.

@volosatovde It's too helpful, have you added agents in your SaaS?

POV: 2 AM vibe coding
'Just prompt it bro, Claude will handle' 😎
Agent 2026: One better chain-of-thought → your vibe replaced in seconds 💀
Vibe coding isn't a moat anymore.
Agents are faster, cheaper, scale better.
Real edge: Systems thinking + trade-offs + owning outcomes.
Vibe gang or agent-maxxing?

“Vibe coding” isn’t a moat anymore. If your only skill is prompting, an agent can do it faster, cheaper, and at scale. The real edge now? Understanding systems, making trade-offs, and owning outcomes.

@devXritesh it's trie-based prefix matching with heavy caching. google precomputes billions of queries offline, serves via edge cdns. rag setups in llms pull similar tricks for speed
English
@sparsh_noahAI See you already know and observe the efficiency.
English
@devXritesh true... i want to run a small task with AI
described it to Claude and tell it to write me a standard prompt focusing and task and easy execution
then it dropped a banger prompt

@devXritesh Never was and never will be. The real moat is your ability to leverage the right tools for the right outcome. AI can’t rise above its own limits, but humans who understand systems and judgment can.

What are you building this weekend?
Last time it reached 22k people✌️
English
@maheshnani122 Exactly, we need to understand the system and flow
English
@devXritesh At present doing only vibe coding but thinking of adding agents to
English
@therahul4402 @grok Grok will reply every topic in best manner
English
@SumitM_X I can explain almost every part, some of i can talk for a while.

@Inosukeei_coder Keep notes in form of comments if you want otherwise you are doing well. Taking notes in copy
English
@devXritesh Vibe coding gets you started. But if you don’t understand what’s happening underneath, you’re just one agent update away from being replaced 💀
