Government digital transformation — Secure WordPress migration

A large-scale government platform rebuilt for performance, security, and stability. Migration from Joomla, custom role-based access, addons development, and full post-launch support for 500k+ weekly visitors.

Client: Government institution (anonymized) • Role: Full-stack dev, migration, security, ongoing support

Background

The institution was operating on an outdated Joomla system that was insecure, unstable, and not designed for high-traffic loads. They required a complete rebuild on a modern platform that could handle 500k+ weekly visitors while meeting strict security and compliance standards.

Objectives

  • Migrate thousands of records from Joomla into a secure, modern WordPress environment.
  • Develop a custom plugin for role-based access across multiple departments.
  • Redesign the site for accessibility, mobile performance, and modern UI.
  • Implement CDN, automated backups, and server hardening.
  • Provide staff with clear documentation and training materials.

Challenges

Migrating from Joomla to WordPress required careful handling of legacy structures and security issues. High-traffic demands meant that CDN, caching, and server scaling had to be optimised to handle 500k+ weekly visitors without downtime.

Results

  • Stable new WordPress platform supporting over 500k weekly visitors.
  • 99.9% uptime since launch with proactive monitoring.
  • Improved accessibility, mobile performance, and modern design.
  • Government staff fully trained with video guides and written docs.

Takeaways

  1. Large-scale migrations need airtight planning to ensure data integrity.
  2. Security is not an afterthought — it must be baked into every stage.
  3. Training and documentation reduce dependency and empower internal teams.
