A personal blog covering backend engineering, security, and practical Python guides. The latest post is an authentication refresher that walks through JWTs, API keys, OAuth2 Client Credentials, webhook signing, mTLS,
RBAC/ABAC/FGA, and defense-in-depth controls. I generated custom 16:9 diagrams for each topic to make the concepts easier to scan.
While building it, I learned how important Open Graph and author metadata are when sharing posts on social platforms. Small details like article:author, og:image, and a canonical URL make a real difference in how a
link preview renders. I also moved from inline floated images to centered figures because they handle mobile layouts more cleanly.
