FAQ
What do you need from me to get started on my project ?
To get started, I will need a brief description of your project requirements, any design references or wireframes (if available), and a list of key features. If your app requires AI capabilities, you will also need to provide your API keys (e.g., Groq).
Can you integrate AI features or RAG systems into an existing website ?
Yes ! Whether you want to build a full-stack AI web app from scratch or integrate custom AI chatbots, RAG pipelines, and vector search into an existing React/Node application, I can seamlessly set that up for you.
What technologies do you use for full-stack and AI development ?
My core tech stack includes React.js, TypeScript, Node.js, Express.js, and MongoDB. For backend scalability and AI integrations, I utilize Redis, BullMQ, OpenAI API, Groq, and MongoDB Vector Search.
Will you handle cloud deployment and hosting setup ?
Absolutely ! I handle end-to-end deployment to ensure your application is live, fully functional, and secure on modern hosting platforms like Vercel or Render.
What if none of the preset packages match my project scope ?
No worries at all ! Just send me a direct message with your specific project details, and I will send you a tailored custom offer that fits your exact requirements, budget, and timeline.
