CodeIgniter

CodeIgniter is the lightweight PHP framework that got a generation of projects shipping with minimal scaffolding. My experience with it spans building lean MVC applications and maintaining mature CodeIgniter codebases.

Its small footprint and shallow learning curve make it effective for fast delivery, and my work there focuses on keeping behaviour organised — models, controllers, and libraries with clear separation — despite the framework's minimal conventions.

For legacy estates I bring disciplined migration paths: isolating dependencies, introducing modern PHP and testing incrementally, and proving out extraction rather than risky big-bang rewrites.

CodeIgniter's appeal is honest: near-zero bootstrap and a tiny footprint make it ideal for simple, fast applications where a heavier framework would be overhead. It proves that disciplined smallest tool can ship real value quickly.

The MVC discipline still applies. I keep models as data/business access, controllers as thin request routing, and libraries for reusable logic — the same cleanliness a larger framework enforces, but done manually where CodeIgniter does not.

Even on a framework this lean, hidden coupling is the enemy. I keep controllers slim by pushing business logic into models/libraries, so the small files stay readable and testable instead of accumulating responsibility.

Legacy maintenance is where most CodeIgniter value sits today. I bring mature apps forward incrementally — introducing Composer where it cannot already, standardising conventions, and adding a testing layer around the risky seams.

Migration is a strategy, not a leap. I isolate a legacy app into a path toward modern PHP and possibly a newer framework, proving each extraction works before it is adopted rather than rewriting everything and praying.

Because CodeIgniter apps are often old and business-critical, treating them with respect and a migration path is the honest craft. It is about keeping working software working while steadily modernising the foundation underneath.

Controllers stay thin even in a minimal framework. I push business logic into models and libraries so the small files stay readable instead of accumulating responsibility.

The simple MVC gets enforced manually. Because CodeIgniter does not force it, I keep request routing, data access, and reusable logic clearly separated by hand.

I work with what the codebase already is. For a mature CodeIgniter app I preserve working behaviour and modernise the foundation rather than gift-wrapping a rewrite.

Legacy maintenance introduces discipline incrementally. I add Composer where it is missing, standardise conventions, and wrap the risky seams in tests before changing them.

Migration is a strategy, not a leap. I isolate an extraction path toward modern PHP or a newer framework, proving each step works before committing to it.

Dependencies and global state are the main risks. I eliminate globals and shrink hidden coupling so the app becomes testable and predictable step by step.

Performance follows the codebase's nature. On a lean framework I keep the serving path light and only add caching where real load demands it.

New work on CodeIgniter is kept appropriately simple. For a lightweight, fast MVP the small footprint is a feature, not a limitation, as long as the structure stays clean.

The craft is respecting business-critical legacy and steadily modernising it — keeping working software working while moving it toward a sustainable future.
