Archetype Core
The Architecture of Intelligent Systems

About

Designing data, AI, and system architecture with clarity and intent.

What Archetype Core is

A technical body of work for engineers who want systems that stay reliable as they scale. The focus is not tools or trends, but the architectural decisions underneath them.

  • Education-first: frameworks, diagrams, and patterns grounded in principles.
  • Systems mindset: reproducibility over ad-hoc fixes and one-off scripts.
  • Applied integrity: examples use anonymized or synthetic data when needed.

Focus

Where the work concentrates:

  • Data platforms and warehouse architecture
  • ETL/ELT orchestration and reliability
  • Applied AI, agents, and workflow design
  • Governance, identity, and observability

Founder

Archetype Core is authored by Mariana Lungu — a Data Engineer focused on systems that are measurable, resilient, and easy to reason about.

Archetype Core is where I publish the frameworks and patterns behind trustworthy systems. The content reflects general engineering principles and open practices, not proprietary systems.
