I’m a full-stack developer specializing in Shopify, backend development, APIs, and integrations. I build and fix Shopify stores, custom checkout flows, payment systems, third-party integrations, and Shopify APIs. I also develop reliable backends with Supabase, PostgreSQL, Firebase, Node.js, authentication, RLS, webhooks, and REST APIs. I work with AI/vibe-coded apps built with Lovable, Bolt, and Replit, connecting the frontend to a secure, production-ready backend. If your store or web app is broken, incomplete, or needs a custom integration, I can help.

FAQ
Which AI app builders do you work with?
I work with Lovable AI, Replit, Base44, Bolt, Cursor, Claude Code, and other compatible AI development tools, depending on the project.
Can you fix an existing Lovable or Replit app?
Yes. I can investigate bugs, broken features, runtime errors, API problems, and incomplete functionality. Please share the issue before ordering.
Can you build a SaaS MVP from scratch?
Yes, for clearly defined scopes. Share your idea, required features, user roles, and backend needs so I can assess the project and provide an appropriate offer.
Do you work with Supabase and Firebase?
I can assist with supported backend integrations, database configuration, authentication, and API connectivity. Confirm your specific requirements before ordering.
Can you integrate APIs or Stripe payments?
Yes, depending on the API, payment flow, project architecture, and access provided. Complex payment integrations may require a custom offer.
Can you deploy my app to Vercel or Netlify?
I can help with deployment and configuration for supported projects. Hosting, domain, environment variables, and third-party service costs are separate.
Can you migrate my app to another platform?
Migration is assessed individually. Share the source platform, destination platform, database details, and features that must be preserved.
What do you need before starting?
I need your project link or code access, a clear task description, relevant error messages, and the expected outcome. Never send passwords in chat.
Will you guarantee that every bug will be fixed?
No blanket guarantee is possible before diagnosis. I will assess the reported issue, define the agreed scope, and communicate any technical limitations.
Should I contact you before placing an order?
Yes, especially for SaaS MVPs, migrations, payment integrations, backend changes, and deployment issues. This helps confirm scope, price, and delivery time.
