Hire CodeIgniter developers to build, support and upgrade lean PHP applications.

There is no single rate for CodeIgniter developers. Cost depends on the seniority you need, the engagement model you choose (adding developers to your team, a dedicated team, or a fixed-price project), how long the engagement runs and the scope of the work. For CodeIgniter work, the biggest drivers are whether the application is on CodeIgniter 3 or 4, how much business logic lives in controllers and views, how many custom libraries and helpers exist, and whether a CI4 migration runs alongside feature development. Share your requirements and we will come back with a quote for your situation.

You tell us the technology, seniority, role and team structure you need. We recommend CodeIgniter developer profiles that match those requirements, and you review the profiles and speak with the engineers yourself before anyone joins your team. When you interview, the areas worth testing are differences between CodeIgniter 3 and CodeIgniter 4 architecture; codeIgniter 4 models, entities and the Query Builder; using filters for authentication, CORS and input validation; migrations and seeders with the Spark CLI; resolving PHP 8 deprecations in CodeIgniter 3 code; and structuring a module-by-module CI3 to CI4 migration.

It depends on which engineers with the right skills are available when you get in touch, so we do not publish a fixed start date. Availability is part of the conversation when we recommend profiles, and the start date is agreed with you before the engagement begins.

Because you interview the engineers before anyone joins, fit is tested before work starts. If concerns come up once the engagement is running, raise them with us directly. How changes to the team are handled is set out in the terms you agree with us at the start.

A freelancer suits small, well-defined tasks you can manage yourself. A dedicated developer joins your team under your direction. A dedicated team adds several roles around your product, and a project-based team delivers a defined outcome end to end.

They work in your time zone or with a meaningful overlap agreed up front, and inside your own tools and process: Slack or Teams, Jira, GitHub or GitLab, your standups, sprint planning and code review.

Yes. CodeIgniter 4 is not backward compatible, so we plan the migration module by module, keep the database stable and test each area as it moves.

CodeIgniter 4 provides ResourceController and the API Response trait for consistent JSON responses and status codes, plus resource routes that map HTTP verbs to controller methods. Filters handle token authentication, CORS and rate limiting before a request reaches the controller.

Yes, if handled deliberately. The web server can route selected paths to a new CodeIgniter 4 application while CI3 serves the rest, both using the same database. Session sharing needs attention, so authentication is often one of the first areas to move.

We move database queries into models and business rules into libraries or services, leaving views to render data only. Doing this one controller at a time, with tests around the affected pages, makes a later CodeIgniter 4 migration much smaller.
