What founders usually ask me about cost, timing, and how I work.
How much does it cost to build a React Native app with AI features?
A React Native app with AI usually runs $25,000-$150,000+ depending on how complex it is. MVPs start at $25,000-$50,000, mid-complexity apps land at $50,000-$100,000, and bigger builds go past $150,000. AI features (chatbots, recommendations, on-device LLMs) add 20-40% on top. My Vibe Coding service ships MVPs starting at $8,999.
What AI features can you integrate into mobile apps?
I build 15+ AI features: chatbots (GPT-4, Claude), voice assistants, image recognition, personalized recommendations, smart search, document scanning, sentiment analysis, and on-device AI models. Cost runs $5,000-$100,000 per feature. Common picks: AI chatbots ($5K-$25K), personalization engines ($15K-$40K), and smart search ($10K-$30K).
How fast can you build an AI-powered MVP?
My Vibe Coding service ships a working MVP in 2 weeks. That covers custom UI/UX, AI features from day one, responsive build, and a product ready to launch. I have helped 10+ founders test ideas fast with AI apps. Typical timing: 2 weeks for MVPs, 4-8 weeks for full products.
Do you specialize in React Native and Expo development?
Yes. React Native and Expo are my core stack, and I pair them with hands-on AI work. I build cross-platform apps (iOS and Android) tuned for AI workloads: on-device LLMs, real-time AI features, and performance work. My apps support model quantization and hold 60fps even while running AI.
What LLM/AI models do you integrate (GPT-4, Claude, Gemini)?
I work with all the major LLMs: GPT-4 Turbo (general chatbots), Claude 3.5 Sonnet (great for code and long context), Gemini 1.5 Pro (multimodal tasks), and on-device models like Llama 3 and Mistral 7B for privacy-critical apps. I help you pick the right one based on cost, latency, and what it needs to do.
Can you build on-device AI features that work offline?
Yes. I do on-device AI with TensorFlow Lite, Core ML, and ONNX. The wins: works offline, no per-request API costs, fast responses (50-200ms), and data that never leaves the phone. Best fit: healthcare, legal, and enterprise apps. On-device models include Llama 3 8B, Mistral 7B, and custom quantized models.
What is AI Workflow Consulting with Cursor AI and Claude?
AI Workflow Consulting helps dev teams put tools like Cursor AI and Claude into their day-to-day work. I cover setup, working patterns, training, and workflow tuning that speeds up developers (typically 40-60%). Starting at $5K. Best fit: mid-sized dev teams and startups that want to use AI dev tools well.
Do you offer white-label AI solutions for agencies?
Yes. I do white-label AI development for agencies and automation consultancies: custom AI chatbots, workflow automations, mobile apps with AI features, and client-ready builds. You keep the client relationship, I handle the build. NDA and white-label agreements available.
