Hi, This is Elias from Miami. I’ve gone through your project details, and from what I understand, you need a skilled React Native or Flutter developer to complete your AI-powered motion tracking app — finishing the codebase, integrating backend APIs, refining the UI/UX from Figma, implementing Canvas-based motion tracking features, optimizing performance, and publishing to both app stores within 2 months. I have extensive experience completing hybrid mobile apps in React Native and Flutter, including real-time features, Canvas integrations, and performance optimization for both iOS and Android. I’ve also worked with AI-assisted modules and motion-tracking workflows, ensuring smooth and production-ready deployment. I’d love to help deliver your app fully functional and optimized within your 2-month timeline. Additionally, I have a few questions regarding your project to clarify the best approach: Q1: Are the Canvas-based motion tracking features already partially implemented, or should they be built from scratch? Q2: Will the AI processing run entirely on-device, or is it server-side with API integration? Q3: Are there any platform-specific performance targets for frame rate or latency on iOS and Android? Looking forward to discussing next steps. Regards.
