They listened, asked the right questions, and delivered

Megan Hayes / Owner | Sep 16, 2026

CalliumCode did good work for us, and we would use them again. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They shared working builds regularly, so we could test early and give feedback before things were locked in. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

The result looks great and performs well, and our internal team found it easy to take over. There were some early misunderstandings on requirements that took a few rounds to sort out. Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with CalliumCode to set up a sensor network and alerts for our cold storage facilities. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 9-month engagement.

Skilled UI/UX Design Team That Understood Our Business

Darragh Walsh / Operations Manager | Aug 29, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The result looks great and performs well, and our internal team found it easy to take over.

If you need a team that communicates well and delivers, they are a good choice.

Great Experience With CalliumCode on Our AI & Machine Learning Project

Rahul Reddy / Founder | Aug 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We launched on schedule and have not had any major issues since.

Happy to recommend them.

Lachlan Smith / Director of Technology | Aug 15, 2026

When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features. We dealt with the same core team throughout, so we did not have to keep re-explaining things.
