About this gig
Need your Next.js app to exchange data with another service? I integrate documented REST APIs and webhooks into existing Next.js and Node.js applications. Basic: one API endpoint or webhook handler with input validation, response handling, and error handling. No new dashboard or database workflow. Standard: one agreed workflow using up to two endpoints, connected to an existing UI and database. Premium: two agreed workflows using up to four endpoints, with testing and handoff notes. Examples include sending form data to a service, displaying an API result, or updating an existing record from a webhook. Required secret configuration and testing are included. New authentication systems, complex OAuth flows, large data migrations, full dashboards, Stripe billing, and AI features need separate scope. API subscriptions and usage fees are paid by you. Send the API documentation, example input, and expected output before ordering. I will confirm the exact endpoints and acceptance criteria.

I'm Nazarii, a full-stack developer working with Next.js, React, Node.js, and TypeScript. I fix bugs, deploy apps, and add APIs, Stripe payments, Supabase, and focused AI features. I also build clearly scoped SaaS MVPs. My portfolio includes event-platform development, e-commerce, and AI-powered tools. I agree on the scope before starting and provide tested changes, source code, and handoff notes. Send the issue or feature you need, and I'll confirm the next steps.

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.
What do revisions and post-delivery support cover?
Revisions cover adjustments within the agreed scope. I include 7 days of support after delivery for reproducible defects caused by my changes. New features, unrelated bugs, and changes to the agreed requirements are quoted separately.
