Developer Needed for an AI-Assisted Life Planner and Shared Scheduling Web App

I’m looking for an experienced developer to build a responsive web app that helps adults plan work, exercise, learning, rest, and personal time, and find suitable times for shared activities. I am not a developer. I can provide a detailed product brief and may create an initial visual prototype in Lovable. Initial scope User registration, login, and private user accounts. Weekly calendar with persistent data. Activities with fixed or flexible schedules, duration, priority, recurrence, and permitted time windows. Automatic placement of flexible activities around fixed commitments, without overlaps. Connections between users to find common availability. Proposed rescheduling of flexible activities, with each affected user’s approval before changes are applied. A responsive interface in English and Spanish. We can communicate in English. Deployment, source code, and basic handover documentation. Please quote Google Calendar integration and Stripe subscriptions separately, describing exactly what each integration would include. Native iOS and Android apps are outside the initial scope. Please state your proposed approach and whether you can continue an existing Lovable project. Your proposal must include Your hourly rate, estimated total hours, and estimated total cost; or a fixed project price. Deliverables, exclusions, milestones, and delivery timeline. Any assumptions or questions that materially affect your quote. Required subscriptions, API charges, hosting, and other ongoing costs. Relevant examples of calendar, scheduling, or multi-user applications you have built. Your included post-delivery bug-fixing period. Pricing and working expectations IMPORTANT!!!! Please submit a genuine estimate for the stated scope. No placeholder bids or low introductory prices followed by a substantially higher quote for the same requirements. Resolve material questions before we agree on the price. We will document the final scope and acceptance criteria before work begins. For fixed-price work, agreed functionality and corrections needed to meet those requirements must be included. Any additional features I request will be quoted separately and require written approval before work starts. For hourly work, we will agree on an hours cap for each milestone. Additional hours require prior written approval. Payments will be made through Freelancer milestones following verification of the agreed deliverables. The project, hosting accounts, and source code must remain under my ownership and control. Please begin your proposal with “Life Planner” and briefly explain how you would prevent scheduling conflicts when flexible activities are moved.
