Hi freelancers, We have a fully functional Matrimonial Application that was recently published on the Google Play Store [Play Store]. The app frontend is stable, but the backend is running on an outdated tech stack. We need an experienced developer or team to upgrade our entire system to modern standards for security, speed, and scalability. Our Current Tech Stack (Advanced Version): • Mobile Frontend: Flutter / Dart (Null-Safety compliant) • Backend Admin Panel: CodeIgniter 3.x • Server Language: PHP 7.4 • Database: MySQL 5.6 (Legacy version) What We Need From You (Scope of Work): 1. Backend Migration: Rewrite and migrate the full admin panel and REST APIs from CodeIgniter 3 to the latest Laravel (11.x or 12.x) on PHP 8.2+ [Laravel 12.x Releases]. 2. Database Upgrade & Migration (Crucial): Upgrade the legacy database safely from MySQL 5.6 to MySQL 8.0+ without crashing tables. You must ensure 100% Zero Data Loss for existing user profiles, matches, and images. 3. Flutter App Code Sync: Update the Flutter mobile app dependencies to the latest stable framework version and connect it seamlessly with your newly built secure Laravel REST APIs (preferably using Laravel Sanctum). 4. Play Store Update Support: Generate a secure, optimized production release file (.aab) and assist us in deploying this update onto our existing Google Play Console account [Play Store]. Project Terms & Rules: • No 100% Advance: The budget will be structured strictly around Milestones (e.g., Milestone 1: Database & Backend setup, Milestone 2: Flutter Integration, Milestone 3: Testing & Play Store Deployment). • You must have clear experience dealing with legacy PHP to Laravel migrations. Experience handling pre-purchased scripts or CodeCanyon scripts is a huge advantage. • Clean, documented code and short post-launch support for bugs are required. Please apply with your fixed-price quote, realistic timeline, and examples of past framework migrations you have handled. Thank you!

Hi, The main risk here is not simply moving CodeIgniter 3 to Laravel; it is preserving the existing matrimonial data, API behaviour, authentication, images, and Flutter app functionality throughout the migration. I can handle this as a controlled migration from CodeIgniter 3/PHP 7.4/MySQL 5.6 to Laravel 12, PHP 8.2+ and MySQL 8, while keeping the existing working functionality intact. I would first audit the current CodeIgniter APIs, database structure, pre-purchased script/customizations, and Flutter API dependencies, then migrate the database with backups and validation before replacing each API/admin module. After that I would update the Flutter dependencies, integrate the new Laravel APIs/Sanctum authentication, test existing user/match/image workflows, and prepare the production AAB and Play Store update. I can provide a milestone-based fixed price and would like to review the current codebase and API/database structure before confirming the final quote and timeline. Thank you

Dear Client, I read "Migrate Matrimonial App Backend from CodeIgniter 3 to Laravel + Update Flutter Code" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with PHP, Mobile App Development, Android, Codeigniter, MySQL, Laravel, Backend Development, Flutter aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak

I have read your job description carefully. You need a safe modernization rather than a rebuild: migrate the existing CodeIgniter 3/PHP 7.4 backend and REST APIs to Laravel 12/PHP 8.2+, upgrade MySQL 5.6 to 8.0+, and keep the existing Flutter application fully compatible. I can approach this incrementally so the live matrimonial data and existing user experience are protected throughout the migration. For the database, I’ll first audit the existing schema, relationships, indexes, stored data and image references, then perform a controlled migration with backups, validation and record-count/data-integrity checks before cutover. The Laravel APIs will be rebuilt with proper authentication/authorization, validation, secure API handling and documentation, followed by Flutter dependency/API integration and regression testing. I’ll also prepare the production AAB and assist with the Play Console update.

I can help with this migration. I have 10+ years of experience with PHP, CodeIgniter, Laravel, MySQL and Flutter, including working with existing/legacy applications. I can migrate the CodeIgniter 3 backend and APIs to Laravel 12/PHP 8.2+, while keeping the existing functionality and data intact. I can also handle the MySQL 5.6 to 8.0 migration, Flutter API integration and Play Store release. For the database, I would first take a full backup and test the migration on a staging environment before touching production. Data integrity and existing user/match records would be checked carefully. I suggest breaking the work into milestones: backend/database, Flutter integration, testing and Play Store deployment. I’m also fine with milestone-based payment and no large advance. I can review the existing codebase first and then give you a realistic fixed-price quote and timeline.

Your Flutter frontend is already stable, so I’d focus on the risky part of this project: migrating the existing CodeIgniter 3/PHP 7.4 backend and MySQL 5.6 data without breaking the live app or losing existing user data. I can migrate the admin panel and REST APIs to Laravel 12/PHP 8.2+, upgrade the MySQL database to 8.0+, and keep existing profiles, matches, images, and relationships intact. I’d handle the migration with backups, schema/data validation, and staged testing rather than making a direct destructive upgrade. After the backend is stable, I can sync the Flutter app with the new APIs, add secure authentication such as Sanctum where appropriate, prepare the production AAB, and assist with the existing Play Store update. I have experience with Flutter, Laravel/PHP, MySQL and existing mobile applications, including working with legacy systems and API migrations. Please share the current CodeIgniter version/customizations and whether the existing app uses a CodeCanyon/pre-purchased script. That will help me give you a realistic fixed price and timeline.
