FAQ
Do I need to provide my own OpenAI API key?
Yes, you will need to provide your own API key from OpenAI (or the relevant AI provider). This ensures you have full control over your billing and usage limits. If you're unsure how to get one, I can guide you through the process.
Can you build a complete SaaS platform with user accounts?
Absolutely. Using Next.js and secure authentication tools like NextAuth or Clerk, I can build a full-scale SaaS application where users can sign up, manage subscriptions (via Stripe), and access their own AI-powered dashboards.
Why do you use Next.js for AI applications?
Next.js is the gold standard for modern web apps. It offers incredible speed, excellent SEO, and "Server-Side Rendering," which is crucial for handling complex AI API calls securely and efficiently without slowing down the user experience.
Can you integrate AI models other than OpenAI?
Yes. While I specialize in OpenAI (GPT-4, DALL-E, etc.), I can also work with LangChain to integrate models from Anthropic (Claude), Google (Gemini), or open-source models hosted on Hugging Face, depending on your project needs.
Do you offer post-delivery support and maintenance?
I provide a support period after delivery to ensure everything is running smoothly and to fix any initial bugs. For long-term maintenance or future feature updates, we can discuss a monthly retainer or a custom milestone.
Do I need to provide the UI/UX design?
If you have Figma files or specific designs, I can implement them perfectly. If not, I can handle the design using modern libraries like Tailwind CSS to ensure your application looks professional and clean.
