FAQ
What tech stack do you use for building AI SaaS applications?
I use robust, industry-standard technologies depending on your needs. For modern, fast frontends, I use Next.js, React, and TypeScript. For powerful backends, I utilize PHP Laravel or Node.js. Databases include PostgreSQL, MySQL, or MongoDB, and I deploy natively to AWS or Vercel.
Which AI models and tools do you work with?
I am deeply experienced in integrating leading Large Language Models (LLMs) including OpenAI (GPT models), Anthropic Claude, and Google Gemini. I also build advanced RAG (Retrieval-Augmented Generation) systems and implement semantic search using vector databases.
Can you handle payment gateways and subscription models for SaaS?
Yes, absolutely. I can implement multi-tier subscription models, consumption-based (pay-as-you-go) billing, and one-time payments using secure gateways like Stripe and PayPal, complete with webhooks for automated user account management.
Do you sign Non-Disclosure Agreements (NDAs) to protect my app idea?
Yes. Intellectual property and confidentiality are highly important to me. Your project details, source code, and proprietary data remain 100% yours. I am more than happy to sign an NDA before we start.
Can you update or add AI features to an existing website or platform?
Yes, I can. If you already have a live website or a legacy application built in Laravel, Node.js, or React, I can seamlessly integrate AI models, build intelligent APIs, or add RAG/chatbot pipelines without breaking your existing features.
Do you offer post-delivery support or maintenance?
Yes, I include 7 days of post-delivery support in the Premium package for minor adjustments, bug fixes, or deployment setup guidance. If your project requires ongoing updates, monitoring, or extended maintenance, we can easily set up a custom monthly paid support plan.
