This Website: Secure Django by Construction

The portfolio itself is a production example: dynamic Django content, PostgreSQL, hardened headers, rate-limited contact, PWA support, health checks and automated tests.

MISSION EVIDENCE 01 Problem 02 Constraints 03 Architecture 04 Outcome

Problem

A portfolio that only claims production engineering is weak evidence. The public artifact should demonstrate the standards it describes.

Constraints

The site must stay fast and visually rich while maintaining a restrictive CSP, no inline executable code, secure cookies, CSRF protection, safe admin boundaries and deploy-time verification.

Architecture & delivery

Built a server-rendered Django application with admin-managed evidence, PostgreSQL-ready persistence, WhiteNoise static delivery, nonce-based CSP, anti-clickjacking headers, HSTS, contact honeypot plus rate limiting, database health checks, sitemap/robots, PWA service worker and test coverage.

Outcome

The site becomes inspectable engineering evidence rather than a decorative landing page.

Public evidence boundary

Enough to inspect the engineering.
Not enough to copy the private system.

Credentials, private infrastructure, proprietary mechanisms, internal prompts, customer-identifying data and implementation recipes are intentionally excluded. Architecture decisions, trade-offs and delivery reasoning can be discussed in an interview.
