FAQ
What AI services do you offer?
I build custom AI chatbots, ChatGPT-powered mobile apps (iOS & Android), AI web applications, and intelligent automation systems using GPT-4, Claude, and Gemini APIs. Whether you need a lead-gen chatbot or a full AI SaaS platform, I can deliver it. Message me to discuss your project.
Can you integrate ChatGPT or GPT-4 into my existing app?
Yes — this is one of my core specialties. I can integrate OpenAI's GPT-4 or any LLM into your existing mobile app, website, or business system via API. I've worked with Node.js, Python, React Native, and Flutter backends. Share your current tech stack and I'll confirm compatibility before your order
How long does it take to build an AI chatbot?
A basic AI chatbot takes 3–5 days. A more complex chatbot with custom training, multi-platform integration (WhatsApp + website), and advanced conversation flows typically takes 7–10 days. I offer express delivery as an add-on if you need it faster.
Do you build both iOS and Android apps?
Yes. I use Flutter to build cross-platform apps that run natively on both iOS and Android from a single codebase. This saves you money and time compared to building two separate apps. AI features, GPT integration, and real-time data are all supported.
What is an AI agent and do I need one?
An AI agent is an automate system that can think, plan, and take actions — like browsing the web, sending emails, updating spreadsheets, or managing tasks — without you manually doing each step. If you want to automate repetitive business workflows, an AI agent is the right solution. Message me now!
Will I receive the source code?
Yes, always. Every project includes full source code, documentation on how to run it, and a handover call if needed. You own everything I build for you.
How do you ensure data privacy and security?
I follow industry best practices — encrypted API keys, secure environment variables, no logging of user conversations unless requested, and GDPR-compliant data handling. For enterprise projects I can sign an NDA before work begins.
Do you offer AI model training or fine-tuning?
Yes, I train and optimize custom AI models based on your data.
How do we get started?
Send your requirements, and I’ll guide you with the best solution.
