FAQ
Do I need to provide my own AI API keys (OpenAI, Claude, etc.)?
Yes. To ensure complete privacy, data ownership, and cost control, you will need to provide your own API keys (such as OpenAI, Anthropic Claude, or Gemini). If you are unfamiliar with how to set them up, I will guide you step-by-step through the process.
What tech stack do you use for development?
For the frontend, I use modern frameworks like React.js, Next.js, TypeScript, and Tailwind CSS. For the backend, I specialize in Python (Django/Django REST Framework) and Node.js/Express. For databases, I work with PostgreSQL, Supabase, and MySQL.
Will I own the full source code and intellectual property?
Yes, absolutely. Once the project is completed and delivered, you will receive 100% full ownership and commercial rights to the entire source code and assets.
Can you help deploy the web application to my server or cloud?
Yes. I provide full deployment setup on platforms such as Vercel, AWS, Docker, Render, or VPS, ensuring your web application is live, SSL-secured, and production-ready.
Do you offer post-launch support after the order is completed?
Yes. I offer dedicated post-launch support to resolve any unforeseen bugs, technical glitches, or setup questions related to the initial project scope.
What if I only have an idea but no technical documentation?
That’s completely fine! Just send me a message describing your concept and target audience. I will help structure the technical roadmap, core features, and user workflow before we begin development.
