FAQ
Can you build a complete SaaS application from scratch?
Yes. I handle the full stack, frontend (React/Next.js), backend (Node.js/Express), database (MongoDB/PostgreSQL), authentication, and payment integration. You get a working MVP or full product, not just a UI mockup.
Do you work with an existing codebase or only new projects?
Both. I can build your project from scratch or join an existing MERN stack codebase to add features, fix bugs, or integrate AI capabilities into what you already have.
Can you add AI features like a chatbot or AI agent to my app?
Yes, this is one of my core specialties. I integrate OpenAI and Claude APIs to build chatbots, AI agents, and smart features directly into your web app or SaaS product.
What APIs and third-party integrations can you handle?
Payment gateways (Stripe), authentication providers, CRM tools, email services, and any REST or GraphQL API. If your project needs custom API integration, message me the details.
Will I receive the full source code?
Yes, complete source code is included in every package, along with basic setup instructions so your team (or future developer) can pick up the project easily.
Do you offer support after the project is delivered?
Yes. All packages include a bug-fix window after delivery, and the Premium package includes extended support for ongoing changes and questions.
What if my project needs something not listed in the packages?
Message me before ordering with your requirements. I'll review the scope and send a custom offer that fits exactly what you need, so there are no surprises later.
Can you help with updates or new features after the project is complete?
Yes. I'm available for ongoing updates, new features, or maintenance after delivery, just reach out and I'll send a custom offer based on the scope.
