I will fix PHP codeigniter mysql javascript bugs and errors in your web application

I fix a wide range of bugs across the full stack, PHP errors and warnings, CodeIgniter routing and controller issues, MySQL query errors and database connection problems, HTML/CSS layout and responsive design issues, JavaScript and jQuery conflicts, API integration errors, session and authentication

Yes — working on existing projects is exactly what this gig is for. I jump into codebases I did not build all the time. I'm experienced with CodeIgniter 3 and CodeIgniter 4, and I follow MVC structure so I can understand your project quickly without needing a long handover. Just share your code.

You can share your project in whichever way is easiest for you — a ZIP file upload via Fiverr, a GitHub or GitLab repository link, Google Drive, or FTP/cPanel credentials if you need me to work directly on a live server. I handle all sharing methods and treat your code and credentials.

Yes. MySQL is one of my strongest areas. I fix broken queries, connection errors, slow query performance, incorrect joins, missing indexes, data integrity issues, and database structure problems. I also fix CodeIgniter Active Record and Query Builder issues that cause unexpected results or crashes.

Yes, I work with both CodeIgniter 3 and CodeIgniter 4. I have deep experience with CI3's MVC structure, hooks, libraries, and Active Record, as well as CI4's updated routing system, namespaces, and Query Builder. Whether your project is on an older CI3 codebase or a newer CI4 build, I can do.

Yes. I fix HTML structure issues, CSS layout bugs, Bootstrap grid and component problems, and JavaScript/jQuery conflicts that break your frontend. I also handle mobile responsiveness — if your site looks broken on phone or tablet, I will identify what's causing it and fix it properly.

Yes. Slow performance is often caused by unoptimized MySQL queries, missing database indexes, excessive server requests, uncompressed assets, or inefficient PHP code. I profile your application, identify the bottlenecks, and apply targeted fixes — query optimization and index improvements.

If the same bug I fixed reappears within 7 days of delivery, message me and I will look at it again at no extra charge. I don't apply quick patches — I fix the actual root cause and document what was changed so you know exactly what was done.

Yes. I can help with deployment issues — moving a site from local to live server, fixing errors that appear after deployment, setting up .htaccess and URL rewriting, configuring cPanel or VPS environments, and resolving server-level PHP or MySQL configuration issues.

Before I start, I need: (1) a clear description of the bug or error — what happens, when it happens, and any error messages you see; (2) access to your project files via ZIP, GitHub, or FTP; and (3) database access if the issue is database-related.
