Design Philosophy

Five principles behind every system in this playbook.

My approach to system design is simple:

  1. Start simple and scale only when needed.
  2. Keep structure consistent across environments.
  3. Separate raw, cleaned, and business-ready data.
  4. Design for repeatability, not one-off solutions.
  5. Build systems that others can understand and extend.

The goal is not just to build systems.

The goal is to build systems that can be reused, scaled, and trusted.
