FAQ
Do you provide both frontend and backend development?
Yes, I offer full-stack web app development — including frontend (HTML, CSS, JS) and backend (Python/FastAPI/Flask) along with AI model integration and database setup.
Can you integrate an existing AI model or API into my current app?
Absolutely! I can integrate your existing AI/ML model, OpenAI API, or any custom API into your web or mobile application seamlessly.
Will you deploy the project online?
Yes, deployment is included for most packages. I can deploy your app on AWS, Google Cloud, or Vercel, depending on your requirements.
What kind of AI models can you build or fine-tune?
I can build and fine-tune deep learning models (CNN, LSTM, Transformers), LLMs, and custom ML pipelines for tasks like image analysis, NLP, classification, or chatbot creation.
Do you provide source code and documentation?
Yes! Every package includes clean, well-documented source code and setup instructions for future scalability.
Can you maintain or update the project after delivery?
Yes, I offer ongoing maintenance, model retraining, and feature updates as separate services after delivery.
What do you need from me to get started?
I’ll need a short project brief, your specific requirements, and any reference datasets or models (if applicable). Once I review it, I’ll confirm the timeline and start immediately.
