Questions

What can you build with Node.js?

APIs for web and mobile apps, back ends for SaaS products, real-time features such as chat and live updates, integrations between systems, and background jobs such as reports and notifications.

Which frameworks do you use?

Express for lean APIs, and NestJS or Fastify when a project needs more structure or speed. Always with TypeScript and tests.

Which Node.js version do you use?

A current long-term support (LTS) release, so you get security updates for years. We upgrade older apps step by step.

Can you work on our existing Node.js app?

Yes. We review the code first, tell you honestly what state it's in, then fix bugs, upgrade dependencies or add features.

How long does it take?

A simple REST API typically takes 3 to 4 weeks, a medium-complexity back end with authentication and integrations 6 to 10 weeks, and large systems 3 to 6 months. Your proposal has the timeline.

How much does it cost?

Every project gets a written proposal after a free call: scope, milestones and one fixed price, plus 18% GST. Payment is usually 40% to start and 60% on delivery; larger projects are split into milestones.

Do you provide hosting?

No. We don't sell hosting. Your app runs on hosting or a server in your name; we help you choose it, set it up and deploy for you.

Do you support the app after launch?

Yes: Node.js upgrades, bug fixes, security updates and new features, by the hour or on a monthly plan.
