What Archetype Core is

A technical resource for designing reliable data platforms and applied AI systems.

Education-first: lessons, diagrams, and frameworks focused on principles — not passing trends.
Systems mindset: architecture and reproducibility over ad-hoc fixes or one-off scripts.
Applied integrity: examples use anonymized or synthetic data to illustrate universal patterns responsibly.

Focus

Where we spend our time:

Data platforms and warehouse architecture
ETL/ELT orchestration and reliability
LLM integrations, agents, and workflow design
Governance, identity, and observability

Founder

Hi, I’m Mariana Lungu — Data Engineer and systems thinking educator.

I design and teach reliable, data-driven architectures with an emphasis on automation, measurement, and clarity. Archetype Core is where engineering meets structure — a hub for frameworks, metrics, and applied intelligence.

Content reflects general engineering principles and open frameworks, not proprietary systems. Archetype Core operates independently from any employer or client.
