FAQ
Can you build a website, web app, and mobile app all together, or just one?
Yes, I can build any one of them individually, or a complete solution (website + web app + mobile app) depending on your project needs. Just message me your requirements and I'll suggest the best approach.
Which AI models or tools do you integrate?
I work with OpenAI (GPT), Claude, and Gemini APIs to build chatbots, content generation tools, RAG/document Q&A systems, and automation workflows tailored to your business.
Do I need to provide my own AI API key (like OpenAI)?
Yes, you'll need to provide your own API key for the AI service you choose. I'll guide you on how to get one if you don't have it already, and help you understand the associated usage costs.
Can you convert my existing website/app into an AI-powered one?
Yes, I can add AI features (chatbot, automation, recommendations, etc.) to your existing website, web app, or mobile app without rebuilding it from scratch.
How long does a typical project take?
It depends on complexity. A simple AI website/landing page usually takes 5-7 days, while a full SaaS platform or mobile app with AI integration can take 3-6 weeks. I'll give you an exact timeline after discussing your requirements.
Do you offer support after project delivery?
Yes, I provide 90 days of free maintenance and bug fixes after delivery. Extended support/maintenance packages are also available if needed.
How do we start the project?
Simply message me with a short description of your project (website, web app, or mobile app + any AI features you want). We'll discuss your requirements, I'll suggest the best tech approach, and once we're aligned on scope and timeline, you can place the order or I'll send you a custom offer to get
