Laravel & Flutter Developer for CodeCanyon Script Update, Merge & Bug Fixes

Project Description: We are looking for an experienced Laravel and Flutter developer to upgrade our existing CodeCanyon food/grocery delivery system to the latest version and fix a few logical bugs left by a previous developer. You will be working across the Admin Panel (Laravel) and 3 Flutter Apps (Customer, Delivery, Restaurant). Scope of Work: 1. Code Merge & Update Update the base CodeCanyon script to the newest version across all 4 platforms (Admin, Customer, Delivery, Restaurant). Carefully merge our existing custom features into the new update. Existing custom features include: MLM Referral system (Admin & Apps) Call Masking API integration UPI Intent (GPay/Paytm direct app open) integration replacing manual UPI ID entry in the Customer App. 2. Bug Fixes (Delivery App & Payments) Razorpay COD Flow: Fix the cash-on-delivery collection flow in the Delivery App. Currently, after a successful payment, the Razorpay page throws an "X not found" error and does not auto-redirect. The rider has to manually go back and refresh the home screen to see the updated zero balance. This needs a smooth auto-redirect/refresh upon success. Incentive Screen Refresh: Fix the Delivery App incentive screen so it dynamically refreshes day-by-day to show current data, rather than getting stuck on old daily incentives. 3. Incentive Logic Adjustment Admin Panel: Configure a gig-based incentive module (Base Pay + Distance-based slabs + Milestone bonuses) based on our existing logic. Delivery App: Display this updated incentive structure clearly to the rider. Note: Delivery men are assigned to fixed zones. There is no requirement for dynamic map integrations or zone-switching UI for the riders.
