FAQ
What can you build with Node.js?
Custom REST APIs and backends for web and mobile apps: authentication, dashboards, payments, real-time chat, notifications and AI-powered features. I work in TypeScript or JavaScript with Express.
Can you work on my existing Node.js project?
Yes. I can fix bugs, add new endpoints, improve performance, or refactor messy code without breaking existing features. Share your repo and I’ll review it before you order.
What technologies can you work with?
Node.js, Express, TypeScript, MongoDB, PostgreSQL, MySQL, Redis, Socket.io, Stripe, PayPal, Twilio, OpenAI, Claude, Gemini, AWS, GCP, Docker and Git.
What does “AI-ready API” mean?
Your backend is built so AI features plug in cleanly: OpenAI, Claude or Gemini calls with streaming, structured JSON responses, function calling, and usage limits to control costs.
Do you provide API documentation?
Yes. Standard and Premium include full Swagger or Postman docs. On Basic, or for an existing API with no docs, I can write complete Swagger documentation for $40. Just message me and I'll send a custom offer.
Do you help with deployment and hosting?
Yes. I can deploy your Node.js backend to VPS or cloud platforms such as AWS, DigitalOcean, Railway or Render. Premium includes it, or add the Server Deployment extra.
Do you offer support after delivery?
Yes, on every package: 5 days on Basic, 7 on Standard and 14 on Premium. For ongoing work, subscribe monthly and save up to
