I am building an AI-powered planning and task management app (Flutter, iOS first) with an AI agent and calendar integration. The UI and part of the agent interface are already built. I now need a strong developer to work with me remotely for approximately 100 hours to finalize: Backend architecture (Node or Python) Secure OpenAI integration (server-side only) Tool calling (tasks + calendar actions) Authentication and per-user data isolation Deployment setup Code structure cleanup and documentation Important: I want to work together live on my Mac via screen sharing (Zoom / AnyDesk / TeamViewer). You will guide me while coding so I understand the architecture and flow. This is collaborative pair programming, not just outsourced development. Requirements: Strong Flutter experience Strong backend experience (Node.js or Python) Experience integrating OpenAI API with tool/function calling Clean architecture mindset Security and privacy best practices Fluent English Able to explain concepts clearly Project Scope: 100 hours total Flexible schedule Remote only Must be comfortable working directly on my machine Please include: Your hourly rate Your total price for 100 hours Your experience with Flutter + AI integrations Links to relevant projects (GitHub preferred) Your availability (time zone + weekly hours) This is Phase 1 of a larger AI platform, so long-term collaboration is possible if the fit is good. Looking forward to your proposal.
