👉🏼 Not owning our infrastructure.

Are you into some certification?

🟢 Is it worth it?

🔴 Or better to pass?

I read you in the comments 👇🏽

When you stop thinking about vibe coding and start thinking about assisted coding work, you see the AI Agent Coding Assistant as a pair programming exercise.

You have to be clear in the communication about what to do, iterate slowly, and review everything.

Do you use AI Agents for coding at work?

From a CTO at a startup:

"We interview devs by giving them a task to build an app on the spot, from scratch (2x BE endpoints, some frontend.) They can use AI, ofc - and we dig into why they did this or that.

What is surprising: 14/15 devs from Meta failed this screening."

Thanks for sharing. Prompt management is a must have if automate more things, from personal workflows towards product we build.

Definitely give Langfuse a try, it is a charm to setup and use.
