AI-Powered Companion App Developer

I am seeking an experienced AI developer or development team to build Luma, an advanced AI companion platform that blends CharacterAI‑style personality chat with deep emotional wellness tools and multiple viral‑ready interactive features. Luma should allow users to create or select characters with distinct personalities, emotional styles, voices or accents, and customizable avatars, while supporting expressive, natural conversation with multilingual capabilities and persistent emotional memory that tracks preferences, tone, emotional patterns, and relationship history. The platform must include a full suite of wellness features such as daily emotional check‑ins, guided journaling, cognitive reframing prompts, mood tracking, supportive empathetic dialogue (not therapy), character‑generated journaling prompts, and a “Talk Me Through It” mode designed to help users navigate stress, loneliness, overwhelm, or difficult emotions. To differentiate Luma from CharacterAI and other AI companion apps, the system should introduce unique viral‑driven elements including an Emotional Memory Graph that visually maps what the AI remembers and how the user’s emotional state evolves over time, reactive avatars with micro‑expressions tied to mood, multilingual emotional support, relationship progression levels, and optional features such as voice mode, AI‑generated voice notes, AI‑generated character images, and expressive avatar animations. Additional viral X‑factors should include AI phone‑call mode for short emotional check‑ins, emotional “story arcs” or seasons that evolve over time, weekly AI‑generated “memory capsules” summarizing user growth, AI‑generated dream sequences based on recent conversations, mood‑reactive home screen widgets, shared journaling between the user and their AI companion, and predictive mood insights powered by emotional‑memory analysis. The project requires a clean, modern UI; secure user accounts; a subscription system with a free tier; an admin dashboard; and a scalable backend using your recommended tech stack (e.g., Firebase, Supabase, or similar). I am specifically looking for developers with experience in AI companion apps, chat systems, emotional‑intelligence features, or wellness platforms who can implement personality systems, memory, expressive avatars, voice features, and viral‑ready interactive elements. Please include your recommended tech stack, estimated timeline, estimated cost, examples of similar apps you’ve built, and any suggestions to enhance Luma’s emotional depth, viral potential, or long‑term user retention.
