FAQ
Can you integrate payment gateways like Stripe or PayPal for SaaS subscriptions?
Yes, I set up secure Stripe/PayPal payment workflows, including one-off purchases, recurring multi-tier subscriptions, and automated webhook handling for payment status updates.
What authentication options can you implement in the Next.js app?
I implement secure authentication solutions like NextAuth, Clerk, or Supabase Auth, supporting email/password, magic links, and OAuth social logins (Google, GitHub).
Will the application be scalable for high traffic?
Absolutely. By leveraging Next.js App Router on Vercel's Edge Network combined with Sanity CMS CDN caching, your platform will easily scale to handle high concurrent user traffic with minimal latency.
