Contact Us →We’re a small team — is custom software overkill for us?
Not at all. Most of our Longueuil clients are small or mid-sized teams — we design everything around the tools you already use, so you get a proper web application or portal without hiring developers of your own.
What kinds of software do you build?
Web and mobile applications, client and employee portals, custom APIs, and SaaS platforms — from UX/UI design through DevOps, built as production-ready systems.
Do you handle UX/UI design, or just the code?
Both — every project includes user research, prototyping, and interface design before development.
Do we need to change our current software?
Usually not. We build around your existing systems rather than replacing them, which keeps the project faster and lower-risk as you scale.
How long does a typical project take?
It depends on scope, but we prioritize getting a working version into production quickly rather than a long build cycle before you see anything.
Is our data secure during development?
Yes — every project follows the same security standards as our managed IT and compliance services, including enterprise authentication through Microsoft Entra ID.
