FAQ
Can you help me scale an app I started on Bolt.new, Lovable or other platform?
Absolutely. Many AI-generated prototypes struggle with scalability and complex logic. I specialize in taking your Bolt.new, Lovable, or Replit exports and converting them into professional, production-ready applications with clean architecture, custom backends, and secure database structures.
Which tech stack do you recommend for a scalable SaaS?
For most modern SaaS products, I recommend Next.js for the frontend due to its excellent SEO and performance, and NestJS or Node.js for a robust backend. For the database, PostgreSQL (via Supabase) or MongoDB are my go-to choices depending on your data structure.
How do you handle SaaS security and user authentication?
Security is my top priority. I implement industry-standard authentication using Clerk, NextAuth, or Firebase. I ensure all API routes are protected, data is encrypted, and best practices are followed to protect your users' sensitive information.
Will I own the full source code once the project is finished?
Yes, 100%. Upon completion and project handover, you will have full ownership of the source code. I provide well-documented code via GitHub or a ZIP file, ensuring you or any future developers can easily maintain and scale the product.
Do you offer post-launch support and maintenance?
Yes. Building a SaaS is a journey. I offer post-delivery support to ensure a smooth launch. Additionally, we can discuss a monthly maintenance retainer to handle updates, new feature requests, and server monitoring as your user base grows.
