Frequently Asked Questions

Common Questions About Working With Me

Everything you need to know before starting your project with me.

What types of Shopify apps do you build?

I specialize in custom Shopify apps including loyalty & rewards programs, mobile app builders, checkout extensions, subscription management, inventory sync tools, and admin dashboard apps. All apps are built using Shopify Remix and Polaris for seamless merchant experiences.

How much does it cost to build a Shopify app?

Shopify app development typically starts at $3,000 for basic apps and can range up to $25,000+ for complex applications with multiple integrations. I provide detailed quotes after understanding your requirements during our free consultation call.

What is your development process?

My process includes: (1) Discovery call to understand requirements, (2) Technical specification & proposal, (3) UI/UX design approval, (4) Agile development with weekly updates, (5) Testing & QA, (6) Deployment & launch support. You'll have full visibility throughout.

Do you offer ongoing maintenance and support?

Yes! I offer monthly maintenance packages that include bug fixes, security updates, Shopify API compatibility updates, and feature enhancements. Most clients opt for ongoing support to ensure their apps remain performant and up-to-date.

Can you build a multi-tenant SaaS platform?

Absolutely! I've built several multi-tenant SaaS platforms with features like subscription billing (Stripe), role-based access control, white-labeling, analytics dashboards, and API access. My architecture supports scaling to thousands of tenants.

What technologies do you use?

My primary stack includes Laravel (PHP) for backend, React/Next.js/Vue.js for frontend, MySQL/PostgreSQL for databases, and Redis for caching. For Shopify apps, I use Shopify Remix, Polaris, and the latest Shopify APIs and Functions.
