FAQ
Will I be able to manage the products and content myself?
Yes! I’ll set up an admin dashboard (or CMS like Sanity) so you can easily add/edit products, prices, and content — no coding needed.
What platforms or tools do you use to build the website?
I use modern, scalable tech like Next.js, React, Tailwind CSS, Sanity CMS, Stripe, and more — all optimized for performance and user experience.
Can I request custom features or designs?
Absolutely! I’m happy to tailor the site to your brand or business goals. Just message me before ordering so I can guide you to the right package or offer a custom quote.
What do I need to provide to get started?
Ideally, I’ll need your logo, product list (with prices/images), preferred color scheme, and any reference sites you like. Don’t worry — I’ll guide you through it.
Do you offer ongoing support after delivery?
Yes! You get free support during the delivery phase, and I offer optional ongoing maintenance as a Gig Extra or monthly retainer. Let’s talk!
Do you offer hosting
Yes — I offer hosting setup as part of Standard & Premium packages. Your site will be deployed on reliable platforms like Vercel (ideal for most Next.js websites) or Render (for backend-heavy applications).
