FAQ
What tech stack do you use to build the SaaS application?
I build SaaS platforms using Next.js (React), TypeScript, and Tailwind CSS on the frontend, paired with Supabase and PostgreSQL on the backend. For hosting and infrastructure, I deploy via Vercel and Cloudflare to ensure sub-second response times, automated SSL, and global edge delivery.
Do I retain 100% ownership of the code and intellectual property?
Yes, absolutely. Once the project is delivered and completed, you retain 100% full ownership of the entire codebase, repository, database schemas, and all integrated assets. There are no proprietary lock-ins or hidden recurring agency licensing fees.
Can you integrate authentication, user roles, and paid subscriptions?
Yes. I implement robust authentication systems (Email/Password, Google OAuth, Magic Links) with strict role-based access control (RBAC). For monetization, I integrate Stripe to handle monthly/annual recurring subscriptions, one-time payments, webhooks, and customer billing portals.
How do you ensure my platform and database are secure?
Security is engineered directly into the architecture. I implement PostgreSQL Row Level Security (RLS) policies to ensure users can only access their own tenant data, sanitize all incoming data against OWASP vulnerabilities, store credentials safely via environment variables, and configure strict HT
Can we start with a Proof of Concept (PoC) or MVP before building the full platform?
Definitely. The Basic and Standard packages are specifically designed for founders who want to validate their idea with a functional MVP or core dashboard before investing in full-scale automation and multi-tenant complexity.
What do you need from me before we get started?
Before placing an order, please send a message with an overview of your idea, the core problem your SaaS solves, any UI/UX wireframes or reference platforms you like, and your preferred launch timeline. I will review the scope and provide an architectural roadmap or a custom offer.
