Principal Engineer @N26 Seems that I like #DomainDrivenDesign 🤔 Facilitating EventStormings since 2019
in the last 9 months part of my focus at work has been generative AI.
Next year I’ll be 100% (or 200% 😂) on that.
One of my goals: find ways to test services calling LLMs at CI time, without making calls to providers.

You want to test a new product or feature, that works with AI (example: recommendation system).
- for testing quickly, maybe use LLMs
- if it works, train your own model if it makes sense

If you introduce a quick, hacky solution just to move fast and you don’t plan to clean it up later, you’re actually hurting the business, not helping it.
Short-term “wins” without long-term thinking usually create tech debt, instability, and slower delivery in the future.

We’re generating docs, code, stuff with LLMs that no one will read.. or probably just LLMs will, because people are lazy and will ask AI to summarise.

Now, with LLMs, they’re also working with Data Scientists.
Inevitably, clashes happen: SWEs follow the “classic” SDLC, while others often don’t.
