Custom software development
Your system or your app, custom-built.
An online store? A dashboard? AI in your tools? A brilliant new app? Describe your idea in your own words: we'll build it with you. We know how to put AI to work, so you get results faster, without sacrificing quality or security.
From beautiful Québec City, we serve clients all over the world via Google Meet.



At the heart of the project: you
You are…
Pick the one that fits you: here's the kind of project we could build together. These are examples, not delivered projects.

Manufacturing, distribution, services, mid-size and large companies…
The information exists. It's just scattered across ten systems.
What slows you down
Systems that don't talk to each other, the same data entered and re-entered from one to the next, and aging tools that slow everyone down.
What we could build
- Links between your existing systems, so information flows without re-entry.
- A production tracking system: throughput, downtime and scrap, by line and by shift.
- AI-assisted automation: documents sorted and summarized, reports that prepare themselves, alerts before a problem occurs. A person always makes the call.
Less re-entry, fewer unplanned stops, and your experts focused on what matters.

Entrepreneur, creator, startup…
You have the idea. You're missing the team to build it.
What slows you down
You can already picture the app. But between design, development, security and publishing to the app stores, the road looks long. And you don't want to hand your idea to just anyone.
What we could build
- Your mobile app, published on the App Store and Google Play, ready to sell.
- Your web app, even a complex one, or your online store.
- A complete commercial app: accounts, subscriptions or payments, dashboard.
- A first prototype, fast, to test your idea before investing more.
Your idea becomes a product you can sell. And it stays yours.

Municipality, non-profit, association, community organization…
Your mission is big. Your resources aren't.
What slows you down
Tight budgets, a stretched-thin team, a colossal load of community engagement and outreach, and never enough time.
Why nrx3
- With AI, we build faster, so it costs you less.
- Reduced rates for non-profits with a social or community mission.
- A custom solution or a website: we have the right fit for you.
Less time on admin, more time for your mission.

How we work
We start by listening
You know your business. We turn what you tell us into the right tool. Five stages, and you always know where things stand.

Listen and understand
We talk, we ask questions, and you show us how the work really gets done, on screen or in person. You talk about your business, not technology.
You get a clear summary of the need and the priorities.
Show you early
Before building everything, we give you a first version to try. You adjust course while it's still easy to change your mind.
You get a prototype in your hands.
Build with you
We move forward in small steps. At each one, you see what works and where the budget stands.
You get regular versions to approve.
Verify
Testing, security, compliance with the laws that apply to you. Nothing goes live without being checked by a person.
You get a reliable tool, ready for real work.
Hand over to you
Onboarding for your team, documentation, follow-up. The goal: you're self-sufficient, with help close at hand when you need it.
You get a confident team and support when you need it.
AI, under control
Try it, with a safety net.
Improvising with AI is tempting: it's fast, until the day it goes off the rails. With us, it stays under control, from day one to delivery. Your project makes it to the finish line, without overruns or nasty surprises.
Years of projects, big and small
Behind nrx3 are years of designing and delivering software of every size. That experience is what lets us judge the quality and robustness of what we deliver. And security is part of the plan from the start: we don't compromise on it.
| Aspect | Improvised AI | With nrx3 |
|---|---|---|
| The code | Generated and copied piece by piece, with no overall control, cursory testing and no code review. | Solid architecture, structured development, an integrated approach. AI builds with the whole project in view to avoid drift. |
| Quality | Without a clear process and good practices, with or without AI, the product suffers. | Controlled at every step: strict AI supervision, code review, automated tests and checks before every delivery. |
| AI answers | AI makes things up and drifts. Without control, an error goes unnoticed and costs time and money, to the point of jeopardizing delivery. | Checked and tied to their sources, so a “hallucination” never makes it to you. |
| Budget | Using AI piecemeal is a step in the right direction, but there's a better way. | Optimized: faster development cuts the bill and leaves room in your budget for other priorities. |
| Timeline | With AI, the work gets done faster than before. | Controlled, well-honed processes speed development up far more. |
| Security | Added at the end, if there's time. | Built in from the design stage, to your requirements and the laws where you operate. |
I'm not a tech person. Is this for me?
Yes. Describe the problem in your own words, the way you'd explain it to a colleague. Turning that into a tool is our job.
Does AI do all the work?
No. It helps us move much faster, but left to its own devices, it quickly drifts off course and produces results that are hard to rein in. It takes experienced developers to steer it and check what it generates: everything is reviewed, tested and validated. That's what makes the final product reliable and high quality.
Is my data safe? Where does it go?
We choose tools and hosting to meet your requirements. We're upfront with you about privacy, the laws that apply and the potential risks, and you stay in control of your data. No sensitive data is sent to an outside service without your consent.
How much does it cost?
It depends on the size of the project. Thanks to our expertise and advances in AI, a project now costs significantly less than it would have just a few years ago. Tell us about yours and see for yourself.
Who owns the result?
You do: the code, the data and the documentation.
What happens after delivery?
We show your team how to use the tool, leave you clear documentation and stay available for support, as you need it.
Do you work remotely?
Yes, and by choice. We've worked remotely for several years: we've mastered it. It lets us balance work, family and social life, and gives us the flexibility to support you effectively. Based in Québec City, we serve clients here and around the world. And when meeting in person helps, in Québec City or near you, we're always happy to.
