Beyond Notebooks: From Experimentation to Engineering in AI
Post #3 — ⚙️ Beyond Notebooks — sharpening engineering thinking in the age of AI.
In Post #2 (https://lnkd.in/emRjNpwU), I shared how I built a text-to-SQL agent. It worked. It generated correct SQL. The answers looked right.
That’s notebook thinking.
But what actually changed my mental model wasn’t improving prompts — it was realizing what I hadn’t built yet: observability, testing, and deployment discipline.
In notebook mode, I inspect outputs manually. In AI engineering mode, I need traces, token and latency monitoring, regression sets that catch semantic errors like misinterpreting qty_delta, and validators that enforce output contracts.
For example, with a regression set, you’ve stored:
- The input question
- The expected SQL or expected result
- Sometimes edge-case annotations
Every time you update the system, you automatically rerun those same cases. If accuracy drops or logic changes unexpectedly, you’ve caught a regression before users do.
In software engineering mode, that same system lives behind CI/CD gates, runs through automated test suites before deploying, exposes metrics and alerts, and is designed to degrade gracefully under failure.
The hardest shift isn’t from data science to AI.
It’s from building something that works to building something that survives.
Print statements aren’t observability.
A few example prompts aren’t testing.
A working demo isn’t deployment.
What changed for me was realizing that observability, testing, and change-over-time thinking aren’t “afterwards” tasks — they define whether you’re experimenting or engineering.
The question I now ask myself isn’t “Does it work?”
It’s “Can I see it break, can I prevent it from regressing, and can it evolve safely?”
That’s the shift.
Check out the chart I created below to compare three ways of thinking: notebooks vs AI engineering vs Software Engineering on aspects at primary goal, workflow, failures, observability, testing, data, deployment, and change over time.
