FAQ
What do I need to provide to get started?
To ensure we hit the 14-day delivery mark, I need a clear user flow (what should the user be able to do?), any existing brand assets (logo/colors), and access to your hosting environment (AWS/Vercel). If you don't have these yet, don't worry—I can guide you through the setup in Day 1.
How do you ensure the MVP can scale to thousands of users?
I don't build "throwaway" prototypes. As a Solutions Architect, I use a scalable stack (Next.js, FastAPI, and PostgreSQL) and implement clean architecture principles. This ensures that when you grow from 10 to 10,000 users, your foundation remains solid without requiring a total rewrite.
Will I own the full source code and intellectual property?
Yes, 100%. Upon completion and final payment, all rights to the source code, database schemas, and assets are transferred to you. I will provide you with full access to the GitHub repository so your team can maintain or scale the product in the future.
Can we add AI features or third-party integrations later?
Absolutely. I architect every project to be "modular." Whether you want to add an OpenAI-powered agent, Stripe payments, or CRM sync next month, the backend is built with documented API endpoints that make future integrations seamless and cost-effective.
Do you offer post-launch support or maintenance?
My goal is to deliver a stable, production-ready app. I include a 7-day "Bug-Free Guarantee" after delivery to fix any technical issues. For long-term growth, I also offer monthly maintenance retainers to handle updates, security patches, and new feature requests.
Is my data and the app’s security protected?
Security is baked in, not bolted on. I implement industry-standard practices including JWT-based authentication, PII masking (if using AI), and encrypted database connections to ensure your user data is safe from day one.
