FAQ
Is Next.js a complete full stack framework for AI web applications?
Yes. As a full stack next js developer, I use Next.js for both frontend and backend. While complex apps previously had backend limitations, modern Next.js combined with Supabase, Prisma and Server Actions provides a complete, scalable full stack solution.
Can you build a complete AI SaaS platform from scratch?
Absolutely. I develop production-ready AI SaaS platforms with user authentication (Clerk/NextAuth), scalable database schemas, Stripe subscription billing and custom AI dashboards tailored to your business model.
Do you build custom AI agents with LangChain and LangGraph?
Yes. As a dedicated AI developer, I build advanced autonomous AI agents and multi-agent workflows using LangChain and LangGraph, including custom RAG systems for intelligent document search and real-time data processing.
Which AI APIs do you recommend: OpenAI, Gemini or free open-source models?
OpenAI and Gemini are great but have rate limits. For long-term cost savings, I can integrate open-source Llama (like Llama 3.2) via high-speed API providers, allowing you to run powerful AI features with minimal or zero recurring API costs.
How do you integrate n8n automation into an AI website?
I connect custom n8n automation pipelines with your web app via secure webhooks. This automates backend processes like lead generation, CRM synchronization, AI content generation and instant notifications seamlessly.
Which backend frameworks do you use for heavy AI computation?
Depending on your architecture, I build secure REST APIs using Python (FastAPI / Flask) for heavy machine learning and AI tasks or Node.js / NestJS for robust, enterprise-grade backend architecture.
What deployment platforms do you support (Vercel, AWS, VPS, Oracle Cloud)?
I handle end-to-end cloud deployment on Vercel for Next.js, AWS (EC2/S3), custom Linux VPS, Google Cloud and Oracle Cloud with Docker containers, SSL certificates and custom domain configuration.
What is included in your custom AI website development service?
You get a modern, responsive UI built with Tailwind, optimized page load speeds, secure database connections (PostgreSQL/MongoDB), custom AI API integration and production-ready, clean code architecture.
Which databases do you recommend for an AI web application?
I primarily use PostgreSQL with Prisma ORM or Supabase for relational data and vector embeddings and MongoDB for dynamic NoSQL data, ensuring ultra-fast queries and high database security.
Can we discuss project details and sign an NDA before starting?
Yes, client privacy and intellectual property are 100% protected. Please send a message with your project scope so we can review the technical architecture, timeline and custom quote before placing an order.
