Suvro Bose
About this gig
I specialize in building intelligent Flutter applications that leverage OpenAI, Claude, and custom LLMs backed by scalable Node.js infrastructure. I don't just write code. I architect AI products that pass App Store review, and actually convert.
What You Get:
Cross-Platform Excellence: One codebase, native performance on iOS, Android, and Web using Flutter
AI-First Architecture: ChatGPT, Claude, Gemini, or custom model integration with streaming responses
Production-Ready Backend: Node.js APIs, real-time databases, authentication, and secure payment processing
Pixel-Perfect UI: Material 3 + Cupertino design systems, custom animations, and responsive layouts
App Store Compliance: GDPR/privacy policy guidance, API key security, and submission support
My Tech Stack:
Frontend: Flutter / Dart
Backend: Node.js, Express, MongoDB, PostgreSQL, Firebase, Supabase
AI/ML: OpenAI API, LangChain, vector embeddings (Pinecone/Weaviate), speech-to-text
DevOps: Docker, AWS/GCP, CI/CD pipelines, TestFlight deployment
Ready to build? Send me your idea even if it's just a napkin sketch. I'll reply within 1 hour.

FAQ
Can you integrate ChatGPT, Claude, or a custom LLM?
Yes. I work with OpenAI, Anthropic Claude, Google Gemini, and open-source models. I also implement RAG (Retrieval-Augmented Generation) for knowledge-specific AI agents.
Do I need to provide my own OpenAI API key?
For development, I use my sandbox keys. For production, you'll need your own API key (I guide you through setup). I never hardcode keys - all credentials use secure environment variables and backend proxying.
What's the difference between Firebase and custom Node.js backend?
Firebase (Starter/Growth) is perfect for MVPs - fast, serverless, cost-effective. Custom Node.js (Scale) is for apps needing complex business logic, third-party integrations, microservices, or handling 10,000+ concurrent users.
Will you publish the app to the App Store and Google Play?
All packages includes full App Store Connect and Google Play Console submission, including metadata, screenshots, and review response.
Do you sign an NDA and transfer full source code ownership?
Absolutely. All packages include full source code transfer and IP rights. I'm happy to sign your NDA before we discuss sensitive details.
