About this gig
Need to connect your Next.js app to a REST API, webhook, data sync, dashboard action, or backend flow?
I help SaaS founders, startups, and product teams add focused backend-connected functionality to existing Next.js apps. This gig is for REST API integrations, webhook handlers, data sync, admin panels, third-party SaaS APIs, and product flows that need clean Node.js backend logic.
What I can add:
- REST API integrations
- webhook endpoints
- data sync between services
- API response handling and validation
- dashboard or admin actions connected to backend data
- clean error handling
- environment variable setup
- short handoff notes
Basic is for one simple API call or webhook endpoint. Standard is for one complete API/webhook flow connected to your app UI and backend. Premium is for 2-3 connected flows or a more complex webhook/API setup with testing.
This gig does not include full SaaS builds from scratch, large backend rewrites, unclear multi-feature scopes, Stripe billing, or OpenAI/AI features.
Please message me with API docs, your stack, the user flow, and the expected result.

Hi, I’m Nazarii, a Full Stack Developer from Ukraine focused on fixing, deploying, and extending Next js apps.
I help founders and small teams with Next.js bugs, Vercel or Render deployment issues, Node.js errors, API integrations, Stripe billing, Supabase, OpenAI features, dashboards, and lean SaaS MVPs.
If you have an existing app, repo, or product idea, I can help debug the issue, connect the missing piece, or get the app live with clean code and clear communication.

FAQ
What kind of APIs can you integrate?
I can work with most REST APIs, webhook-based services, and backend-connected product flows when the service has usable documentation.
Do you need my existing app?
This gig works best for existing or partially built Next js apps where a focused feature or integration needs to be added.
Can you handle webhooks too?
Yes. Webhook handling can be included depending on the integration and package.
Can you build a full dashboard with this gig?
This gig can add dashboard-connected features, but a full custom dashboard is a larger scope and may need a custom offer.
Does this include Stripe or OpenAI integrations?
No. This gig is for general API and webhook integrations. Stripe billing and OpenAI/AI features should be scoped under their dedicated gigs.
Do you need API documentation?
Yes. Please send the API docs, webhook docs, test credentials if available, and the exact flow you want inside your app.
Do I get the source code?
Yes. You receive the source code, and I can also work directly in your repository.
