FAQ
What do you need from me to get started on my AI project?
To get started, I need a brief overview of what your web app or tool should do, any reference websites or wireframes you like, and your preferred AI features. If you are not sure about the technical stack, just describe your business idea and I will recommend the best architecture.
Do you provide the OpenAI, Anthropic, or API keys?
No, you will need to provide your own API keys for services like OpenAI (GPT) or Anthropic Claude. I will guide you step-by-step on how to set up your developer accounts, add payment methods, and securely generate your keys so you retain full control over your billing.
Can you build an AI chatbot trained on my private documents and PDFs?
Yes. I build custom RAG (Retrieval-Augmented Generation) chatbots using LangChain and vector databases like Pinecone and Supabase. The chatbot references your uploaded PDFs, spreadsheets, or knowledge bases to deliver accurate answers without hallucinating.
Can you integrate AI features into my existing website or web app?
Absolutely. If you already have a functional frontend or backend, I can build custom REST APIs and integrate AI endpoints, interactive chatbots, or automation workflows directly into your current platform without disrupting existing
Can you handle user authentication and Stripe payments for an AI SaaS?
Yes. For SaaS platforms, I integrate authentication (NextAuth, Supabase Auth, Clerk) and configure Stripe for one-time credits or recurring monthly subscriptions, along with protected dashboard routes for paying users.
How do you protect my data and API keys?
Security is built in from day one. All sensitive API keys and secrets are stored in secure server-side environment variables and never exposed to the client-side browser. I also implement rate-limiting to protect your endpoints from abuse and unexpected toke
Do you handle live deployment and domain setup?
Yes. Depending on your stack, I can deploy your full-stack AI web app on platforms like Vercel, AWS, Render, or Docker, connect your custom domain, and verify SSL certificates so your application is completely production-ready
Do you provide source code and post-delivery support?
Yes, every project includes clean, well-commented source code delivered via a GitHub repository or zip archive. I also provide post-delivery testing support and a video walkthrough to show you how to manage and run the application.
Do you work with models beyond OpenAI, such as DeepSeek, Claude, Gemini, Grok, or Qwen?
Yes. While OpenAI (GPT) is common, I frequently integrate open and commercial models depending on your budget and use case. I work with DeepSeek (V3/R1) for cost-effective reasoning, Google Gemini for multimo
Can you build end-to-end AI workflows using n8n, Make.com, Zapier, Retell AI, or ElevenLabs?
Yes. I design intelligent business automations combining workflow orchestrators with conversational voice and language models. Whether you need custom webhooks and logic pipelines in n8n or Make.com, automa
