I will connect your nextjs app to apis, auth, stripe or database
Marcelo Farias
Sobre este Serviço
Do you have a Next.js app that looks good but does not work yet?
I can help you connect your app to real functionality: APIs, authentication, database, Stripe payments, forms, CRUD, dashboard data or backend logic.
I work with React, Next.js, Node.js, TypeScript, Prisma, PostgreSQL, Supabase, REST APIs, Auth.js/Clerk and Stripe.
I can help with:
REST API integration
Auth/login flows
Database connection
Form submission
CRUD operations
Stripe Checkout
Dashboard data
API routes / server actions
Error handling and loading states
How it works:
1. You explain what needs to be connected.
2. You send the current code, API docs or repository access.
3. I review the scope and confirm the best package.
4. I implement the integration cleanly.
5. I test the main flow and explain what was done.
Please contact me before placing an order.
This Gig is for one clearly defined integration or flow. Full SaaS development, large dashboards, full business systems, major refactoring or complete app development require a custom offer.

Perguntas frequentes
What do you need to start?
I need a clear description of the integration, repository access or relevant files, API documentation if available, test credentials when needed, and the expected result.
Can you integrate external APIs?
Yes. I can connect your Next.js app to REST APIs, third-party services, backend endpoints or external platforms if the API documentation and access credentials are available.
Can you add authentication?
Yes. I can help with login flows, protected routes, user sessions and authentication logic using Supabase Auth, Clerk, Auth.js or custom authentication.
Can you integrate Stripe payments?
Yes. I can integrate Stripe Checkout or a clearly defined payment flow. Subscriptions, complex billing or marketplace payments may require a custom offer.
Can you connect my app to a database?
Yes. I can connect your Next.js app to a database using Prisma, PostgreSQL, Supabase, MongoDB or similar technologies.
What counts as one integration?
One integration means one clearly defined feature or flow, such as connecting one form to an API, adding login, connecting one dashboard section to data, or integrating one payment flow.
Do you build complete SaaS apps in this Gig?
This Gig is focused on integrations inside an existing app. Complete SaaS platforms, large dashboards or full business systems should be discussed as custom projects.
