FAQ
Do you build Next.js SaaS apps with authentication and payments?
Yes. I build production-ready SaaS apps using Next.js App Router, React 19, TypeScript, Supabase or Drizzle, Clerk or NextAuth for authentication, and Stripe or LemonSqueezy for subscription billing. Source code is fully yours on GitHub.
Can you fix my Lovable, Bolt, v0, Cursor, or Replit AI app?
Absolutely. AI builder fixes are a daily job for me. Send me your Lovable, Bolt, v0, Cursor, Replit, or Base44 project link and I will fix hydration errors, broken auth, failed deployments, database errors, and Stripe issues. Typical turnaround is 24-72 hours.
Do you use shadcn/ui and Tailwind CSS for the front end?
Yes — shadcn/ui + Tailwind CSS is my default. I also use Radix UI primitives, Lucide icons, Framer Motion for animation, and shadcn/ui blocks for dashboards. The UI will be modern, responsive, dark-mode ready, and accessible by default.
ill you integrate authentication like Clerk, Supabase Auth, NextAuth, or Auth.js?
Yes. I integrate Clerk, Supabase Auth, NextAuth (Auth.js), Kinde, or Better Auth. Role-based access control, social login (Google, GitHub, Apple), magic links, and protected routes are all included.
Can you set up Stripe or LemonSqueezy subscriptions and webhooks?
Yes. I set up Stripe Checkout, subscriptions, customer portal, webhooks, and metered billing. I also work with LemonSqueezy, Paddle, and Polar. Production-grade error handling and idempotent webhook processing included.
Do you build on top of Payload CMS, Sanity, or Strapi?
Yes. Payload CMS v3 is my favorite headless CMS for Next.js. I also build with Sanity, Strapi, Contentful, and Hygraph. I can also migrate from WordPress to a headless CMS + Next.js stack.
Can you build a Next.js admin dashboard with charts and data tables?
Yes. I specialize in shadcn/ui admin dashboards — sidebar navigation, command palette, data tables with server-side pagination, charts (Recharts or Tremor), forms with React Hook Form + Zod, and dark mode.
Do you deploy to Vercel and configure custom domains?
Yes. Vercel deployment, custom domain setup, environment variables, edge functions, ISR, and image optimization are all part of the standard delivery. I also deploy to Cloudflare, Netlify, Railway, or your own VPS.
Is the source code mine after delivery? Will you hand over the GitHub repo?
100% yours. I push to your GitHub repo with clean commits, README, .env.example, and setup docs. No lock-in, no proprietary frameworks, no GPL traps. You own the code.
Do you offer post-delivery support and bug fixes?
Yes. Every order includes 14 days of free post-delivery bug fixes. After that, I offer monthly maintenance retainers. I also offer free 15-min scoping calls before you order — message me first to confirm scope and timeline.
