Secure Web Application Coding

Think like a bug hunter. Secure applications without breaking functionality.

The Audit Mindset

Vulnerabilities rarely live in obvious "security" code. They hide in parsers, normalizers, transformers, and renderers — the mundane plumbing that moves data through your app.

Trace from attacker input:

• Start at ingress points (forms, URLs, headers, uploads, APIs, webhooks, imports)
• Follow data through every parse → normalize → transform → render → fetch step
• Treat each step as a new trust boundary

Review the invisible:

• Framework defaults (parsers, content-type handling, redirect behavior)
• Parser selection and configuration
• Feature composition — benign features can chain into severe bugs, including RCE
