Looking for Full Stack Developer to Build Mobile App MVP - React Native + Node.js

Hi, I have an idea for a mobile app and I need an experienced developer to help me build the first working version (MVP). I don't need anything perfect at this stage, just functional, clean, and ready to show to early users and potential investors. What the app does: It's a task management app for small teams, think a lightweight version of Trello but simpler. Teams can create tasks, assign them to members, set deadlines, and track status (To Do, In Progress, Done). What I need built: Mobile app (iOS + Android) using React Native User authentication (sign up, log in, log out) Create, edit, delete tasks Assign tasks to team members Status tracking (To Do / In Progress / Done) Simple dashboard showing task overview Backend API with Node.js + Express Database to store users and tasks (MongoDB) What I'll provide: App concept and rough wireframes Branding colors and app name Feedback throughout the build Budget: Fixed price Timeline: Need it till Monday Note: Please only apply if you've built and shipped a real mobile app before. Share examples.
