My SaaS platform is currently written in PHP with no framework support. As the codebase grows, small bugs and performance hiccups are becoming harder to track, so I want the entire application ported to CodeIgniter. The goal is a cleaner, more maintainable structure that runs reliably on shared and VPS environments without changing the core behaviour my customers already rely on. What I need from you • Analyse the existing codebase, map its modules, and propose an equivalent CodeIgniter architecture. • Rebuild the application inside CodeIgniter, keeping every existing screen, endpoint, and process intact. • Refactor common utilities into controllers, models, and views, following CodeIgniter best practices. • Thoroughly test the migrated app so that all current functionality works exactly as it does today. • Hand over the full CodeIgniter project with installation instructions and a concise migration report. Acceptance criteria 1. Application installs through CodeIgniter’s standard process with no fatal errors. 2. All existing user flows (login, billing, data entry, reports) behave identically to production. 3. No PHP warnings or notices appear in error logs during normal use. 4. Clear documentation covers environment setup, deployment, and a summary of major code changes. I’ll give you access to the current repository, database schema, and a staging server to validate the migration. Let me know your estimated timeline and any questions about the current stack.

Hi, I can migrate your existing PHP SaaS into CodeIgniter while keeping all current functionality exactly the same. I’ve refactored legacy PHP applications into framework-based structures before, focusing on cleaner architecture, better maintainability, and stable performance on shared and VPS hosting. I’ll first analyze your codebase and map it to a proper CodeIgniter MVC structure, then rebuild modules using controllers, models, and views, following best practices. All user flows—login, billing, data entry, reports—will be thoroughly tested to match current production behavior. You’ll receive the full CodeIgniter project with clear setup instructions and a concise migration report. Happy to review the repo and confirm timeline details.

Hi! I can migrate this cleanly to CodeIgniter without changing what your customers see. Which CodeIgniter version do you want (3 or 4), and are you currently on PHP 7.x or 8.x? The root cause of the “small bugs everywhere” feeling is usually scattered business logic and shared globals with no consistent request lifecycle, so debugging turns into archaeology. I’ll start by mapping modules, routes, DB interactions, and shared utilities, then translate them into a CI structure with controllers/models/views plus a clear config/env setup. After that I’ll port each screen and endpoint one-by-one, keeping behavior identical, and refactor utilities into reusable libraries/helpers so the code stops duplicating itself in five different places. Finally, I’ll validate every user flow on staging, kill notices/warnings, and deliver the full CI project with install steps and a concise migration report. Happy to jump on a quick call to review the repo structure and give you a tighter estimate once I see module count and integrations. Best, Vadym
