FAQ
What do I need to provide before we start?
Please provide a brief description of your project idea, any wireframes or design references (Figma/sketch links if available), brand assets (logos, images, copy), and access to any third-party accounts or APIs needed (e.g., Stripe, database, hosting).
Can you help deploy the application?
Yes! Deployment is included. I can deploy your web app on platforms like Vercel, Netlify, Render, or set it up directly on your cloud VPS/server so it is live and ready for your users.
Do you provide the full source code?
Absolutely. Upon completion and delivery, you receive 100% full ownership of the clean, documented source code with zero vendor lock-in.
Can this MVP scale as my user base grows?
Yes. The application is built using modern standards and modular architecture, making it straightforward to add new features, expand the database, or refactor components down the line.
