JUST.engineer Reviews

Exceeded our expectations on quality and communication

Mitch Nguyen / Founder | Aug 25, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Blockchain Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We are already discussing the next phase with them.

Project summary

We hired JUST.engineer to develop and audit smart contracts for a tokenized loyalty program. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 2-month engagement.

Reliable Blockchain Development Partner That Delivered What They Promised

Lena Koch / Director of IT | Jul 31, 2026

I would rate this engagement highly on almost every front. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We launched on schedule and have not had any major issues since. Overall, a team we trust and plan to keep working with.

Easy to work with and very transparent on timelines and cost

Megan Nguyen / Senior Product Manager | Jun 19, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. We would definitely work with them again.

Project summary

Our company worked with JUST.engineer to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 6 months.

Capable Low-Code / No-Code Development team — happy with the end result

Zoe Taylor / Director | May 01, 2026

The final product works well for us, although the process could have been smoother. They shared working builds regularly, so we could test early and give feedback before things were locked in. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We are already seeing better numbers than before the project. We had to follow up a few times on smaller bug fixes after launch. We would definitely work with them again.

Project summary

We engaged JUST.engineer to build a quick MVP on a low-code stack to test our idea. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 5-month engagement.
