I need a professional Flutter Developer to complete a project. Our Dev had to abandon and we need help to take his work and complete. The application is very simple and has the foundation work (framework / authentication) done and is missing some views, navigation and most importantly a fully working Chat. Among the skills required are: - Firebase Storage/Realtime DB/cloud Functions (for chat, notification & media) - Experience Deploying to IOS, Android & web (from single flutter codebase) - Experience with Routers, Apis, Providers, Models, Exceptions, etc. This project is a Marketplace app (so it has 2 views: Vendor & Client) and it basically is a Chat Service between both after authentication & vendor/product navigation. The uniqueness is that It can host multiple tenants to enable multiple marketplaces. Project is about 40 views out of which aprox 10 are already built. It was estimated at $3,000 USD so we are hoping to keep this as our capped budget (to complete in 3 months). All Backend APIS and FIGMA designs are complete (or near completion) The most "complex" issues have already been solved/prepared: Firebase Auth, Notification, Deep Links, GeoLocation, Mobile Access & Permits, Api requests, etc. The work is really about completing and building the most awesome chat possible. If you are interested Please provide a sample of a Chat app that you have built using Flutter. We would like to see your git/code to evalute your dev style. only Apply if you have these skills, agree on the budget/time and have a similar project in portfolio. Please include in your reply ALL of the following, otherwise we will not consider: 1) Subject: chaas (mention this to make sure that you are not autobid) 2) Demo: link to your github of ANY flutter app 3) Demo: link to appstore Google/IOS of a working chat app. 4) Introduction: Why are you the right developer for us? 5) please let us know if you speak Spanish (without AI!) Note.. DO NOT SEND GENERIC LINKS TO GENERIC APPS.. WE WANT TO SEE FLUTTER/CHAT SPECIFIC. AND PUBLISHED. thank you!
