Archetype Core by Mariana Lungu

Archetype Core is a practical way to build data systems that actually hold up in the real world.

I’m Mariana Lungu. I’m a senior data engineer, and I spend my time designing data platforms where security, governance, and reliability are not afterthoughts.

On this channel, I break down how data systems are built in practice. The decisions behind the architecture. The trade-offs teams avoid talking about. The places where things quietly fail.

You’ll see:

* How I approach data engineering and architecture
* What “secure pipelines” actually mean in practice
* Where AI helps and where it makes things worse
* How to think about governance without turning it into bureaucracy

This channel is for engineers and leaders who care about building systems they can stand behind, not just systems that ship fast.

Archetype Core isn’t about trends.
It’s about judgment.

If that’s how you think too, you’re in the right place.
