FAQ
What exactly do you build in this gig?
I build custom full-stack web applications and SaaS MVPs using Base44, Antigravity, Next.js, Node.js and Supabase. This includes frontend UI, backend APIs, authentication, database design, Google OAuth integration, deployment, and production-ready architecture.
Can you build a complete SaaS platform with login and dashboard?
Yes. I develop secure SaaS platforms with role-based authentication, admin dashboards, user management, database logic, API integrations, payment gateways, and scalable backend systems using Next.js and Node.js.
Do you integrate Google OAuth and third-party APIs?
Absolutely. I integrate Google OAuth, REST APIs, webhooks, CRM systems, payment processors, and external services to ensure your web app connects seamlessly with the tools your business already uses.
What technologies do you use for backend and database?
I use Node.js for backend logic, Base44 or Supabase for database architecture, secure API handling, authentication systems, and scalable data management suitable for SaaS MVP and production apps.
Will my web app be scalable and secure?
Yes. I implement secure authentication, database policies, optimized server architecture, clean API structure, and performance optimization to ensure your web application is scalable and production-ready.
Can you convert Base44 or Lovable projects to WordPress or iOS?
Yes. I can migrate Base44 to WordPress, convert Lovable builds to WordPress, or prepare projects for iOS deployment using tools like Capacitor while maintaining functionality and structure.
Do you provide deployment and hosting setup?
Yes. I deploy applications to Vercel, Replit, or custom hosting environments, configure environment variables, domain connection, database setup, and ensure your project is live and stable.
What kind of projects is this best suited for?
This service is ideal for SaaS MVP development, internal dashboards, booking systems, subscription platforms, chatbot web apps, reporting tools, admin portals, and custom automation systems.
Do you offer revisions and ongoing support?
Each package includes structured revisions. I also provide post-launch support options to ensure your Next.js, Node.js, and Supabase system continues running smoothly after deployment.
How long does development take?
Basic MVPs typically take 3–5 days. Full-stack SaaS builds range from 7–15 days depending on features like authentication, API integrations, dashboards, and payment systems.
