Day 4.

Interview module is coming together.

Create interview → AI questions → respond → continue the conversation.

Spent today testing everything in Postman and fixing small issues.

Slowly getting there.

Just finished “Agentic Frontend Development with Codex” by @katiagz at OpenAI.

3.5 hrs well spent. learned to actually direct Codex instead of just asking it to write code.

Day 3.

Wired up MongoDB and the User model today.

Added `process.exit(1)` if the DB connection fails on boot - sounds dramatic, but it's really just "don't let a broken server pretend to be healthy."

[Tejas kumar @Tejas_devv]

@blackbox_lab Yeah exactly. Not the exciting stuff, but it’s the foundation 🙌

[Tejas kumar @Tejas_devv]

Day 2.

Built the auth system -> JWT + bcrypt + MongoDB.

Also lost 40 minutes to a TypeScript error before realizing it just wanted `import type` instead of `import`.

Unglamorous work, but the app doesn't exist without it.

@PhantomC0der Not yet.😅 Right now I’m using the LLM directly for the interview flow. I want to get the core system solid first, then experiment with an agent layer on top of it.

[Tejas kumar @Tejas_devv]

@Heyy_Meet Yeah, that’s something I want to explore. Right now I’ve kept PrepDost JWT-based, but I’m curious to compare it with stateful sessions once the core backend is done.

[Tejas kumar @Tejas_devv]

@rizwandev99 Haha yeah, that import type error definitely felt personal 😂
Appreciate the follow! Always good to connect with other builders.

[Tejas kumar @Tejas_devv]

@awxshhhh Thanks man 🙌 appreciate it. More to build.

[Tejas kumar @Tejas_devv]

Day 1.

Mock interview apps charge $96/mo and still don't have a DSA round.

So I'm building one that does - voice interviews, live coding, AI feedback. Free & open source.

Starting today. Who's building something too?

A few days ago, I started learning Agentic AI

Learning by building, not just watching tutorials.

So far:
• Tool calling
• Agent loops
• Multiple tools
• Tool registry
• Pydantic validation
• Error handling & retries

[Nishant Singh @nishantsingh211]

sometimes the best AI strategy is not using AI at all.

If the rules are already known, there’s no ambiguity, and the output needs to be exact, adding an LLM can make the system slower, more expensive, and less reliable.

AI isn’t always the answer
Sometimes, good engineering is

People got so fed up with Sony that they literally said 'we'll just make our own PS5' and here we are. SharpEmu is what happens when you push a community too far 💀#Gaming

Solving DSA by pattern > solving random questions.

Two Pointers → Sliding Window → Prefix Sum → Binary Search → BFS/DFS → Backtracking → DP → Heaps → Topological Sort

Depth > volume.

@nishantsingh211 Not all heroes wear capes. some just run dark mode 24/7.
