Worked with Microknot over a period of 4 months to build a financial simulation & visualization of supply chain activities. Microknot architect and engineers provided the framework, design & setup on Azure and the development activities. It was a great experience working with them!

Kel A's Review Sourced from Google
The EDI system that Microknot created was a little slow to start up due to the complexity of our system. But it's now reached a point where it's saving me time with our orders. The team were prompt in responding to emails & were a pleasure to work with.

Dave Philips's Review Sourced from Google
We have enjoyed working with Jag, Shaun, and several of Microknot's developers over the past 18 months. The Microknot team has allowed us to accelerate the time to market for our platform, translating to money in the bank and added scale to our internal development team without the risks, time delays, and costs associated with hiring new staff.Microknot's professionalism in managing our project has also lifted the game for our internal team. Not only have they delivered a great product outcome, but we've also learned a lot about different technologies and effective s/ware PM methodology in the process.The Microknot team have been responsive, easy to work with, delivered every sprint on time, and significantly contributed to guiding our application in the right direction.I can't thank the team at Microknot enough for their contribution to Biode, and I would not hesitate to recommend them to any business looking for a trusted development partner.
