## Methodology: The 5D Framework

Diagnose - Design - Develop - Deploy - Defend

- **Diagnose:** Audit existing site, codebase, and infrastructure before writing code. Find what is broken, insecure, or holding performance back.
- **Design:** Architecture decision before implementation. Staging environment mirrors production.
- **Develop:** Version-controlled, peer-reviewable code. The same standard Munich Re's IT team reviewed.
- **Deploy:** Staged rollout. Production push only after full staging sign-off.
- **Defend:** Post-launch monitoring, security hardening, backup verification.

## Canadian Compliance Expertise

- **CASL** - Canada's Anti-Spam Legislation. Explicit opt-in consent for commercial email.
- **PIPEDA** - Federal privacy law. Mandatory breach notification. Relevant for healthcare, financial services, professional services.
- **WCAG / AODA** - Web Content Accessibility Guidelines. Legal requirement for government and regulated industries.
- **Official Languages Act (EN/FR)** - Federal bilingual requirement for government and national brands.
- **Quebec Law 25** - Quebec privacy law, stricter than PIPEDA.
