FAQ
What AI APIs and models can you integrate into my web app?
I integrate OpenAI (GPT-4o), Google Gemini, Claude, and DeepSeek. I also set up RAG pipelines with vector databases (Pinecone, ChromaDB) for custom AI chatbots, knowledge bases, and automated workflows.
What is GEO / AEO SEO, and why is it important in 2026?
Generative Engine Optimization (GEO) & AEO structure your website with semantic schema markup so AI search engines (ChatGPT Search, Perplexity, Gemini, Copilot) can easily parse, index, and feature your site in direct AI search answers.
Which tech stack do you use for full-stack AI development?
I use modern, scalable tech stacks including Next.js, React, Tailwind CSS, Node.js, Express, Python (FastAPI), MongoDB, and PostgreSQL. Every build is optimized for fast loading speeds, Core Web Vitals, and mobile responsiveness.
Do I need to provide my own AI API keys?
Yes, you will provide your API keys (e.g., OpenAI, Gemini). I will securely configure environment variables, implement usage safeguards, and guide you on how to manage API costs efficiently.
Can you handle both front-end and back-end development?
Absolutely! I specialize in both front-end (UI/UX design, responsive layouts) and back-end (server logic, database management) development. This ensures a seamless user experience and robust functionality.
Can you build a full AI SaaS MVP with user payments?
Yes! I develop complete end-to-end AI SaaS applications, including user authentication, database architecture, admin dashboards, custom AI prompt engineering, and Stripe payment gateway integration.
