FAQ
What stack do you use?
Next.js 15 App Router, React 19, Tailwind CSS, PostgreSQL with Prisma ORM, and NextAuth v5 for authentication.
Can you deploy the app for me?
Yes. Standard and Premium packages include deployment to Vercel or AWS EC2 with HTTPS and environment configuration.
Do you work with existing codebases?
Absolutely - I can add features to your existing Next.js or React project, not just build from scratch.
Can you integrate third-party APIs or payment gateways?
Yes. I have production experience with Stripe, Adyen, HyperPay, WhatsApp API, and many other integrations.
What do you need to get started?
A brief description of what you need, any designs (Figma, screenshots, or even a rough sketch), and your preferred tech stack if you have one.
