FAQ
What information do you need to get started?
I need a brief description of your project goals, key features you want, any design preferences or references, and your target users. A rough wireframe or existing design is a bonus but not required.
Can you integrate Al features like ChatGPT or OpenAl into my app?
Absolutely. I specialize in integrating OpenAl GPT-4, Claude (Anthropic), Gemini, and LangChain pipelines into web and mobile applications. This includes chatbots, Al content generation, semantic search, RAG (retrieval-augmented gener
Will you deploy the application to a live server?
Deployment is unavailable due to fast shipping time.
Can you handle payment gateway integration (Stripe, PayPal)?
Yes, payment integration is one of my core specializations. I implement Stripe (one-time payments, subscriptions, webhooks), Razorpay, and other gateways. I handle secure checkout flows, webhook event processing, subscription manage refunds, and PCI-compliance best practices.
What happens if the deliverable doesn't meet my expectations?
I offer a structured revision policy - 1 revision on Basic, 3 on Standard, and 5 on Premium. Before starting, I create a detailed specification document for your approval, which eliminates most misalignments. If there's ever a genuine issue, I work transparently to resolve it.
Can you work on an existing codebase / fix bugs in my project?
Yes. I can review, debug, refactor, and extend existing codebases across my tech stack (MERN, React, Node.js, Flutter, FastAPI, PHP, Java/Kotlin Android). For existing projects, I always start with a code audit to assess scope before quoting message me with your repo details.
