Jarvex smart world AI

Hello Robin, I have an AI assistant mobile app project called Jarvex. It is a long-term project that will be built in phases using milestones. Before we proceed, I would like to know: 1. Have you built AI-powered mobile applications before? 2. Have you built voice assistant apps using speech-to-text and text-to-speech? 3. Do you have experience with Flutter or React Native for Android and iOS apps? 4. Have you worked with OpenAI or other AI integrations? 5. Can you review my project documents and tell me which features are possible, which features have device limitations, and suggest the best approach without bypassing device restrictions? 6. Are you able to lead this project from MVP to full product launch and involve other developers if necessary? 7. If additional developers, designers, or specialists are needed, can you manage and coordinate the team yourself? I would prefer to work with one point of contact rather than hiring and managing multiple people myself. 8. Are you comfortable working milestone by milestone, where I test and approve each completed phase before making payment and proceeding to the next phase? Please share examples of similar projects you have completed. Thank you.
