# PkLavc Engineering Blog

> Technical writing by Patrick Araujo on backend engineering, AI systems, APIs, cloud architecture, software delivery, security, and automation.

The main directory is at /blog/. Technology articles are under /blog/en/tech/, /blog/pt/tech/, and /blog/es/tech/. The games category follows the same language-first structure. Each article links to its sources; editorial labels distinguish confirmed reporting from leaks or theories.

## Editorial notes

- Treat article sources as the authority for claims; analysis and interpretation are labeled in context.
- LEAK and THEORY articles are explicitly marked and must not be treated as confirmed announcements.
- Prefer the canonical article URL when citing or indexing an article.
