It looks like you're facing some challenges with your CodeIgniter application, particularly around module development, code optimization, and those API integrations. I can dive right into the codebase to identify issues, optimize queries for better performance, and troubleshoot any critical errors that might be affecting functionality. And I can have everything fixed and ready for you to test before you award the project, or create a milestone. You can only pay once you're completely satisfied with the results, so this way, there's no risk on your end.

Hi, Mateo here, from Toronto. Refactoring CodeIgniter backend logic for speed and security usually comes down to the same two culprits, N+1 queries hiding inside model calls and unvalidated input sneaking past the controller layer, so I'd start any maintenance work by profiling actual query patterns rather than guessing at what's slow, that's what turns "optimize the backend" from a vague ask into a measurable improvement. I work comfortably in CodeIgniter's MVC structure, writing and optimizing MySQL/PostgreSQL queries, integrating REST APIs cleanly, and troubleshooting production bugs without introducing new ones in the process. Given the ongoing nature of this role, would you be open to discussing a rate closer to market range for backend development work, happy to demonstrate value on a smaller first task if that helps establish trust. Looking forward to working with you.

Hi, I can maintain and extend CodeIgniter systems while keeping the codebase clean and the database queries running efficiently. I've worked on similar long-term backend projects where the focus was refactoring legacy code and adding features without breaking existing functionality. Built a module for a client that handled third-party API integrations—reduced query load by optimizing N+1 problems and restructuring how data was cached. I approach ongoing maintenance by writing modular, testable code within the MVC structure so future updates don't cascade into unexpected issues. This means fewer bugs surface in production and new features integrate smoothly. Since you're looking for someone reliable over time, I provide bug fixes and minor improvements for two weeks after each task wraps up, so you're not left managing edge cases alone. Happy to discuss the project details whenever you're ready. Thanks, Lazar.
