CodeIgniter Development

CodeIgniter development worldwide. New CI4 applications, CI3-to-CI4 migrations, REST APIs, and legacy codebase maintenance — built by a developer with 14+ years of PHP experience.

CodeIgniter development — new builds and legacy upgrades

CodeIgniter remains one of the most performant PHP frameworks available. Its small footprint, straightforward MVC structure, and excellent documentation make it an ideal choice for businesses that need a reliable, maintainable backend without the complexity of larger frameworks.

What we build

  • New CodeIgniter 4 applications — built from scratch to specification
  • CodeIgniter 3 to CodeIgniter 4 migrations — full upgrade path
  • Legacy CodeIgniter 2 and 3 maintenance — bug fixes and security patches
  • REST APIs in CodeIgniter — consumed by mobile apps or headless frontends
  • Custom authentication and authorisation systems
  • Third-party integrations — payment gateways, SMS, email, shipping APIs
  • CodeIgniter performance audits — query optimisation, caching, profiling

Why CodeIgniter

CodeIgniter has a minimal footprint — no configuration overhead, no magic, no steep learning curve for your in-house team to inherit. Applications are easy to understand, easy to test, and fast to deploy. If you have an existing CodeIgniter codebase, we can extend it without a full rewrite.
