Flutter Mobile Developer — Long-Term Equity-Based Opportunity at Chef AI About Chef AI Chef AI is an AI-powered cooking and food assistant currently being developed under CYCORP. The product is already well underway. The backend infrastructure and APIs have been developed, and the Flutter mobile application is substantially built. We are now looking for a Flutter Mobile Developer to join the team for the long term, complete the remaining development and integration work, and continue developing the product as Chef AI grows. This is not a traditional freelance project. We are looking for someone who wants to become part of the journey and grow with the company. Compensation — READ BEFORE APPLYING THIS IS AN EQUITY-BASED POSITION. There is NO fixed salary, hourly rate, monthly stipend, or upfront cash payment for this role. The compensation structure is: - 5% milestone-based equity in Chef AI/CYCORP, subject to the agreed milestone structure and applicable legal documentation. - One-time $5,000 bonus when Chef AI reaches $100,000 in cumulative collected revenue. If you are only interested in a traditional paid freelance contract, please do not apply. We understand that equity-based opportunities are not suitable for everyone. We are specifically looking for developers who understand startup risk and want the opportunity to participate in the long-term success of the product. Current Project Status The project is already significantly developed. The existing backend includes: - User management - Authentication - JWT-protected APIs - Chat functionality - AI recipe generation - Subscription verification - Subscription status management - API documentation for mobile integration The Flutter application is also substantially developed.

Hi, I understand Chef AI is already substantially developed, with the backend APIs and Flutter application in place, and you need an experienced Flutter developer to take over the existing codebase, complete the remaining development, handle the integrations, testing, and prepare the Android app for Google Play launch. I will review the existing Flutter codebase, integrate it properly with your JWT-protected APIs and AWS Cognito, complete Google Play Billing and AdMob integration, make sure premium users don't see ads, fix any remaining issues, and handle the final APK/AAB builds and end-to-end testing for release. This will help you get the existing application production-ready without rebuilding everything from scratch, while also having someone who can continue maintaining and improving the product as Chef AI grows. I have experience working with Flutter, Dart, REST APIs, authentication, subscriptions, ads, and existing mobile codebases. I also understand that this is an equity-only opportunity with the 5% milestone-based equity and the $5,000 revenue milestone bonus, rather than a traditional paid freelance project. I am comfortable discussing the long-term structure and contribution. Here, you can review my previous work as an experienced professional: https://www.freelancer.com/u/Hammadhassan21 I can start immediately. Let's discuss further. Thanks.

Hello!! I understand you need a Flutter developer to take ownership of the existing Chef AI app, complete API integration, Cognito authentication, subscriptions, AdMob, testing, and prepare reliable production builds for Google Play. • Which parts of the existing Flutter app are still incomplete? • Do you have the current source code and API documentation ready? • Which Android devices should be prioritized for testing? Strong Flutter and Dart experience, REST API integration, authentication, subscriptions, advertisements, Git, and production app development can help move Chef AI smoothly toward launch. Relevant mobile projects have been completed by working with existing codebases and delivering stable, user-friendly applications. Building a product for long-term growth rather than simply completing tasks is exactly the approach I bring. Let us connect in chat to discuss the current codebase and milestones.

hello, Taking over a substantially built Flutter app is a different job from building one, and the smart first move is understanding the existing codebase before touching the remaining tasks, since inheriting someone’s architecture means the integration work goes smoothly only once you know how it is already wired. Your task list is mostly integration, Cognito, Play billing, AdMob, and those all touch the same auth and user-state layer, so I would map that first, since the premium-versus-free ad logic depends entirely on the subscription status flowing cleanly through the app. The piece I would treat carefully is the ads-versus-premium boundary, since ensuring paying users never see an AdMob ad while free users do means the subscription check has to gate the ad calls reliably, and getting that wrong is both an annoyed paying customer and a Play policy risk. The Play release itself I would plan for early too, since billing and ads both draw review scrutiny. On the equity structure, I will be straight with you, that is a commercial decision only you can weigh, since it trades guaranteed pay for a stake in the outcome, so whether the risk suits you is yours to judge, not something I would decide. Is AWS Cognito already partially wired on the backend side, so the app integrates against a ready setup, or is that auth flow being built fresh? And roughly how complete is the Flutter app, mostly done with integrations left, or are there unfinished screens and features too? One honest note before you commit: this posting offers no payment, only equity plus a bonus tied to future revenue, so there’s no fee here unless the product succeeds. That’s yours to weigh, but worth being clear-eyed that a bid here is betting on the outcome, not billing for the work.

Hi, Taking over an existing production Flutter codebase and finishing the API integration is the kind of work I do most, so a partly built app plus documented backend APIs is a good starting point for me. One question before anything else. Is the 5% equity vested over the milestones and backed by signed legal documents before work starts, or does it accrue only after the $100k revenue mark? That changes how I'd plan the commitment. On the technical side, we built a full event platform with a React Native mobile app on an AWS backend with OAuth SSO and Stripe payments. I've also deployed and integrated REST APIs on AWS across several contracts, all rated 5 stars. If you can share the repo access and current API docs, I'll review the codebase and map out the remaining integration work. What state is the Google Play Billing piece in now? Adil

Hello! As per your project post, you are looking for a Flutter Mobile Developer to join the long term development of Chef AI, an AI powered cooking and food assistant that is already substantially built. Since the backend infrastructure, APIs, and much of the Flutter application are already in place, the priority is to complete the remaining mobile development, integrations, testing, and prepare the product for continued growth. My focus will be on reviewing the existing Flutter codebase, understanding the current application architecture and API workflows, completing unfinished screens and functionality, integrating the existing backend services, resolving UI and functional issues, improving performance, and ensuring a consistent experience across iOS and Android. I can also continue supporting new features and product improvements as Chef AI evolves. I specialize in Flutter, mobile application development, API integration, AI powered applications, performance optimization, debugging, and long term product development. My focus will be on working within your existing architecture rather than unnecessarily rebuilding what is already working, while keeping the codebase clean and maintainable. Let’s connect to review the existing Flutter application, current development status, and product roadmap so I can become a reliable long term development partner for Chef AI. Best regards, Nikita Gupta.

Hello, Chef AI looks like a partially completed mobile product with a real backend behind it, not a concept-stage app, and that usually makes the handoff risk more important than the remaining feature list. The real engineering risk here is ownership transfer of an existing Flutter codebase while keeping auth, subscription state, ad suppression, and release behavior consistent across edge cases. Most of my work is on AI SaaS architecture and API-backed production systems, including DocIntel AI and Dent-Cloud, where I designed secure application flows, service boundaries, and long-lived production integrations. That background is relevant to the backend/API side of this product, especially around JWT-protected APIs and AWS-backed auth patterns. I usually structure this kind of handoff by separating codebase audit, API contract verification, entitlement logic, and release hardening so defects are found before store submission rather than after launch. That said, this role is primarily a Flutter/Dart ownership position with Google Play Billing, AdMob, APK/AAB release work, and Android publishing at the center. Based on the stack in your JD, I would only be credible on the architecture, backend integration, and production-readiness side, not as the strongest direct fit for the mobile implementation itself.

Dear Client, I read "Equity-Based Flutter Developer for Chef AI" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with Mobile App Development, Android, Backend Development, Flutter aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak

I’ve shipped and maintained Flutter apps with REST backends, Google Play Billing, and AdMob in production, so API-heavy mobile work like this is routine. The codebase will get a full review first to map endpoints, auth flows, and ad-conditional logic before I push changes to feature branches. I’ll wire the existing JWToken auth to AWS Cognito, drop in Google Play Billing for subscriptions, and flip AdMob banners conditionally based on subscription status—no blocking issues if the backend endpoints stay stable. APK/AAB builds will hit the Play Console via CI, then we validate across three Android generations before release. I can start immediately. Thanks, Andrii.
