Technical reflections and development insights recording the programmer's growth journey
Systematic prompt engineering primer covering three core techniques: Few-Shot examples for style injection, Chain-of-Thought for complex reasoning, JSON Schema enforced structured outputs for downstream systems. Includes real templates and anti-patterns.
End the API style debate: compared across 7 dimensions - network efficiency, DX, evolution cost, caching, type-safety, security risks, ecosystem - with clear decision tree and hybrid architecture patterns.
Advanced patterns: CQRS separate read/write models for query performance; Event Sourcing using events as source of truth for audit + time travel. Covers consistency, snapshots, idempotency pitfalls and anti-patterns.
Comprehensive JWT vulnerability playbook: alg confusion attacks, key brute force, KID injection, replay defenses. Compare OAuth2(+PKCE), OIDC, SAML 2.0 across dimensions for protocol selection.
