Core Engineering Principles

Understand fundamentals deeply before adopting frameworks.

Design systems for graceful failure and self-healing.

Measure and profile rigorously before optimizing.

AI systems are software and distributed systems first.

Reliability, security, and observability are first-class architectural concerns.

Learn by building, testing, and deconstructing real systems.
