FAQ
I already have an app. Can you add AI features without rebuilding it?
Yes. I specialize in "AI Retrofitting." Whether your app is built on Flutter, React Native, or Native languages, I can integrate OpenAI (GPT-4o), Anthropic (Claude), or custom LLMs via APIs. I’ll ensure the AI components connect seamlessly with your existing backend without disrupting anything.
How do you keep my AI API costs low so I don't get a huge bill?
This is a common concern. I implement "Token Optimization" strategies, such as prompt engineering to keep responses concise, implementing local caching for frequent queries, and using "Lite" models (like GPT-4o-mini) for simple tasks.
Will my app be rejected by the App Store for using AI-generated content?
Apple and Google have specific guidelines regarding AI (especially around safety and "Minimum Functionality"). I ensure your app stays compliant by implementing robust content filtering, reporting tools for AI outputs, and ensuring the app provides "utility" beyond just being a wrapper for a chatbot
Can the AI "learn" specifically from my private business data?
Yes. I use a technique called RAG (Retrieval-Augmented Generation). Instead of expensive fine-tuning, I connect your app to a Vector Database (like Pinecone or Supabase). This allows the AI to "read" your PDFs, spreadsheets, or docs in real-time and provide accurate answers based only on your data.
Why use Flutter for an AI app instead of Native development?
For 95% of AI startups, Flutter is the winner. It allows us to ship to both iOS and Android simultaneously, cutting your development cost and time-to-market by nearly 40%. Since AI processing happens in the cloud/backend, you get native-level performance with a much faster update cycle.
How do you handle user data privacy and GDPR/CCPA compliance?
Privacy is paramount. I build with "Privacy by Design," ensuring that sensitive user data is encrypted and that AI interactions are anonymized before being sent to third-party APIs. I can also implement "Opt-in" features for AI tracking to ensure your app is legally compliant globally.
Do I need to provide the UI design, or do you handle that?
I can do both. If you have Figma files, I’ll follow them to the pixel. If not, I provide Prototyping services. I focus on "AI-UX"—meaning I design interfaces specifically meant for interaction with intelligent agents (like specialized chat bubbles, voice-to-text animations, and streaming text effect
What happens if the AI model (like OpenAI) goes down?
I build for "Resiliency." I implement Failover Logic where the app can either switch to a backup model (e.g., from GPT to Gemini) or display a graceful "Maintenance" state to the user. Your app won’t just crash; it will handle the interruption professionally until the service is restored.
