Node.js development for APIs, real-time apps and back ends

We build Node.js back ends, APIs and real-time features for web and mobile products, from field-staff platforms to AI chat assistants. Our in-house team builds and supports Node.js applications, and you own the code we write for you.

What we build with Node.js

Examples from our own projects, described in general terms.

APIs and integrations

REST APIs behind web and mobile apps, and connections to payments, maps, Microsoft Graph and other services.

Real-time and chat features

Streaming chat and voice, notifications and live updates, such as the back end of an AI chat assistant. See the Reactor case study.

Field and workforce platforms

Scheduling, duty and incident reports and training records on a MEAN stack, with iOS and Android apps. See the GoAquatix case study.

Security and compliance portals

A React and Node.js portal that reads a customer's Microsoft Secure Score and tracks the fixes. See the RiskA case study.

Location and marketplace back ends

Map IDs with route guidance, and buy-and-sell marketplaces with separate customer, vendor and driver apps.

Performance and code reviews

Reviews of existing Node.js code for speed, scaling and security, with the fixes listed in order of impact.

When Node.js is the right choice

Node.js suits products where many small requests and live updates matter:

  • APIs behind web and mobile apps.
  • Chat, notifications and dashboards that update while people watch.
  • One language, JavaScript or TypeScript, from the browser to the server, with React or Vue in front.

For heavy calculation, or a team already strong in another stack, .NET or PHP may serve you better. We will say which we would choose and why.

What clients say

Jatinder has been a valuable team player and leader for us as we worked to develop our revolutionary technology. Recently, we integrated our software into Oracle's technology and our code went through and passed the Oracle review process for certification which is in large part due to Jatinder's talent, attention to detail and professionalism.

The highest recommendation for our software developers is to rehire them for future projects and Jatinder has earned this recognition more than any software developer on our team. We look forward to continuing to work with Jatinder in the future and delighted to be able to leave this positive feedback for him today as it has been so well deserved.

Manjinder has been great to work with on our project. He has been with us for over 3,000 hours of work and is one of the best programmers we have worked with on a project (we have worked with over 50 developers.) I highly recommend Manjinder from both a professional and personal level. He possesses superb ASP.net and SQL skills plus great communications skills making him the ideal candidate for any small, medium or large-scale development project.

Sarbjit did a great job moving our public blog from BlogEngine.NET to Wordpress. This migration contained a lot of complexities, users, comments and database structure that had to be moved and Sarbjit handled it masterfully. Thanks Sarbjit!

Great dev. Worked on a pretty complicated custom build node.js app that functions as part ERP, CRM, Inventory Management, and more. Tech built is better/more advanced than VC backed competitors of ours. Great job.

Frequently asked questions

When is Node.js a good choice?

Node.js suits APIs, real-time features such as chat and live updates, streaming and single-page app back ends. For heavy CPU work, other runtimes can be a better fit.

Do you build APIs and real-time applications?

Yes. We build REST APIs and real-time applications, and we can work in TypeScript. See our NestJS and TypeScript pages.

Can you review my existing Node.js application?

Yes. We review the code, look for performance and scaling problems, and suggest what to change first.

Do you sign an NDA, and who owns the code?

We sign an NDA before work starts, and you own the code we write for you.

How do I get a quote?

Use the form on this page or book a project call. Tell us what you need and we come back with questions and next steps.

How can we work together?

There are three ways, on the same terms:

  • Dedicated team, best for ongoing work: interview the developers, then they work on your project full or part time.
  • Fixed scope, best when requirements are clear: we agree the scope and the price up front, and deliver against it.
  • Time and material, best when the scope will change: you pay for the time used and can change priorities as the work goes on.

Whichever you choose, we sign an NDA before work starts, you own the code we write, and every change is reviewed in your repository.

Can I interview the developers before we start?

Yes. For a dedicated team you meet the developers in an online call and interview them before they join your project.
