FAQ
Can you build my web app from just an idea?
Yes. You can send me your idea, goals, and key features. I’ll help break it into a clear, practical plan before development starts.
Do you handle both the frontend and backend?
Yes. I handle the full stack, including the frontend, backend, database, APIs, authentication, and deployment, so everything works together properly.
Can you build an MVP or SaaS product?
Absolutely. I can build a focused MVP, SaaS, or custom web application around the features your users actually need, without overcomplicating the first version.
Can you work on an existing web app?
Yes. If another developer started the project, I can re-view the existing code, fix issues, add features, improve performance, or continue development from where they stopped.
Can you integrate APIs, p-ayments, or AI features?
Yes. I can integrate REST APIs, p-ayment gate-ways, AI tools, third party services, and automation based on what your application needs.
