We are looking for a serious and committed mobile app developer to join the development of Chef AI, an AI-powered SaaS platform that helps users discover and generate personalized recipes. This is not intended as a casual side gig or short-term freelance task. We want someone who believes in the product, can commit to completing the mobile application professionally, and is interested in growing with the platform over the long term.

Integrate the existing backend APIs. Implement authentication and user accounts. Integrate AI recipe generation and chat functionality. Implement Google Play Billing on the Android client side. Build subscription and premium-access flows. Handle testing, bug fixing, optimization, and Play Store launch preparation. Continue supporting the application as the platform grows under the agreed long-term arrangement. Compensation: 5% equity, earned through agreed development and continued-involvement milestones rather than being granted entirely upfront. One-time $5,000 cash bonus when Chef AI reaches $100,000 in cumulative collected revenue, subject to the final written agreement. This opportunity is intended for someone comfortable with an equity-based startup arrangement rather than standard upfront project payment. We are looking for someone who: Has strong mobile app development experience. Has experience integrating REST APIs and authentication systems. Understands Google Play Billing and subscriptions. Communicates consistently and meets agreed milestones. Is serious about building a production-quality product. Wants to become a long-term technical contributor as the platform grows.

Hi, Chef AI is already past the risky part: backend, Cognito auth, protected routes, and core AI/chat APIs are in place. I can now connect the mobile app cleanly, ensuring sign-in, session handling, API calls, and premium access all work reliably on Android. My focus would be on the core flow: user authentication, loading app state, sending chat/recipe requests, Google Play Billing integration, restore-purchase logic, and clear handling for free vs. paid access. I’ll also tighten loading states, error handling, and edge cases so the app is stable before Play Store submission. Relevant experience: - Mobile app structure and navigation - Cognito login and session flow - AI recipe/chat API integration - Google Play Billing and subscription access - Testing, bug fixes, and launch readiness Timeline: I can start immediately and would first build and stabilize the core flow, then move into billing, testing, and final release checks. One quick question: is this Android-only for now, or should I choose a framework that can later support iOS too?

Hello, I have built production mobile apps with REST APIs, account systems, subscriptions, and store release work. Chef AI already has AWS backend, Cognito login, user and chat APIs, and recipe generation, so the mobile side needs careful integration rather than kitchen chaos. I would build the app around the existing flows, connect authentication, AI recipes, chat, Google Play Billing, premium access, testing, and launch preparation. I understand this is an equity-based long-term role, not a quick snack-sized task, and I would work through clear milestones with steady communication. Best regards, Teo

It looks like you've already done the hardest part by putting a solid backend in place, so the mobile app is really about connecting those pieces into a polished product people will actually enjoy using. My first step would be validating every existing API, authentication flow, and subscription endpoint against the mobile client so there are no surprises later. From there I'd build the core experience around recipe generation, chat, and account management before integrating Google Play Billing and premium access. I've worked on products where the backend was already established, and careful integration early on saved a lot of rework during testing and release. I mainly build with Flutter because it keeps the codebase maintainable while delivering a native feel on Android, and I pay close attention to offline handling, loading states, and failed AI responses so the app remains reliable even when external services are unavailable. I'm interested because this feels like a product that can keep evolving rather than a one-off build. One thing I'd like to know is whether the mobile UI should follow the existing web design closely or if there's room to optimize the experience specifically for mobile. I'm ready to get started.
