I have, multi-platform codebases—6amMart and eShop Plus— Need To Run on Web, iOS, and Android. I’m looking for a single developer or small team to handle a round of feature upgrades and fixes that touch both products. Core scope • UI revamp on every platform, refreshing the layout structure, color scheme, and typography without disrupting existing workflows. • Refactor our Razor pay and in-house bank gateway flows to use payment-intent logic, then squash any related bugs. • Implement rich push notifications for 6amMart (images inside the notification tray). • Add an in-app alarm/reminder system for both the seller and delivery apps so partners never miss an order. • For eShop Plus only: – Introduce a full subscription module. – Integrate Msg91 for phone-based OTP sign-up and login. – Enable delivery confirmation that captures both photo and OTP. – Build a dynamic “available delivery time slots” picker visible during checkout. – Enhance the existing combo-products feature. • Integrate a third-party delivery-agency API across products for real-time status updates and label generation. What I’ll provide • Current source code with environment instructions. • Design references and brand guidelines for the new UI.(Figma File) • API keys for Razor pay, the bank gateway, Msg91, and the delivery-agency service. Acceptance The updated builds must compile and run on Web, Xcode, and Android Studio with no critical errors; all new flows should be demonstrated in a staging environment before merge. Clear, commented commits and a concise change log are required. If you have solid experience in Flutter/Laravel (or the relevant stacks) and can deliver this moderate-sized upgrade in an organized, test-driven manner, let’s talk timelines and milestones.
