Good day
I am a full-stack developer with experience in AI integrations and mobile applications for iOS and Android. I have created voice assistants, AI chats, and subscription products, including for a children's audience; the architecture is clear and functional. I have already implemented such a pipeline and understand where delays, ASR/TTS errors, and budget overruns typically occur.
I implement Flutter to write PCM WAV 16 kHz mono with auto-stop on silence.
The backend on Strapi accepts audio, processes it through Google Speech-to-Text, forms a prompt from the system prompt, rolling summary, latest messages, and user text, receives a response from Gemini, voices it through Gemini TTS, and returns text + audio. On the client side, the correct states are Idle Listening, Thinking, Speaking.
I implement context and memory exactly as described in ai_sessions with rolling_summary, ai_messages with the latest messages, and auto-cleaning by TTL. This is cost-effective in terms of tokens and scales well. Regarding child safety, there is a strict system prompt, short responses, filtering of dangerous topics, prohibition of personal data, and logging of problematic cases without storing voice.
I handle the Flutter part carefully: stable recording, network error handling, fallback in case of ASR/TTS failures, minimal delay between responses.
For subscriptions and limits, I check active subscriptions, limits on time and number of requests, and protection against abuse. I have worked with Apple IAP and Google Play Billing.
I understand AI as a production system, not an experiment; I know how to work with children's products and a fixed stack, and I think about scaling and cost from the very beginning. I am ready to discuss timelines, stages, and start with the backend or Flutter React Native. If needed, I can first finalize the API architecture and Strapi models.

Hello! You have well outlined the pipeline. I have developed several "secretary" applications with AI. Also gemini + other models for savings. Adding an assistant is not a problem for you.

Hello, I have worked with something similar, for example, I created such a manager with animation https://217-154-170-186.nip.io/ for embedding on websites. I have also developed a number of mobile applications, including children's ones; for instance, I worked on an application where AI generates fairy tales for children. I would be happy to collaborate.
