FAQ
Do you build the AI features from scratch, or use existing APIs?
I integrate proven AI APIs (OpenAI, Claude) into your app rather than training models from scratch. This gets you a reliable, production-ready AI feature faster and cheaper than custom model development and it's what most businesses actually need.
What if I already have a website/app and just want to add AI to it?
That's exactly what my Integration package covers. Send me your existing codebase or a link to your app, and I'll scope what's needed to add chatbot, automation, or AI features without rebuilding what you already have.
What tech stack do you work with?
React, Next.js, Node.js, Supabase, and Firebase for full-stack apps; Flutter and React Native for mobile. For AI, I work with OpenAI and Claude APIs, RAG pipelines, and automation tools like n8n.
How long does a typical project take?
A simple functional web app takes 4 days. A full-stack app with AI integration typically takes 7 days. Complex builds with fine-tuning or multi-step automation can take up to 2 weeks. I'll give you an exact timeline once I understand your requirements.
Do I get the source code and full ownership?
Yes. Source code is included in all packages, and you own everything I build for you. No ongoing licensing or dependency on me to maintain it
