FAQ
I don't have technical knowledge, can you still help me?
Absolutely! Just tell me which service you want to connect (e.g., "I want Stripe payments on my website") and I'll handle all the technical work. No jargon, clear communication.
Can you integrate OpenAI / ChatGPT into my website?
Yes! I can integrate OpenAI's API (GPT-4, DALL-E, Whisper) into any web app. This includes chat interfaces, content generators, and AI-powered features.
Will the integration work on my existing website?
Yes. I work with your existing codebase regardless of the stack — React, Node.js, Python, PHP, WordPress, Shopify, without breaking what already works.
How do you handle API security?
I store all API keys as environment variables (never hardcoded), implement rate limiting where needed, and follow the security guidelines of each provider.
What if the integration breaks after delivery?
I provide 7 days of free support after delivery. If something breaks due to my code, I fix it for free.
