We engineer new cloud native, enterprise-grade applications
We help build bulletproof, mission critical applications that you can scale up and down and which won’t crack under pressure. That’s what we mean by enterprise-grade.

We modernise older, legacy and monolithic applications
We love to break down and re-engineer creaking, complex applications to be truly fit for their future on the cloud. We’re talking containerisation and microservices to build in more flex and scale whenever you need it.

We don’t do straight ‘lift and shift’
We see good old lift and shift as ‘moverisation’ rather than modernisation – and so it’s not our bag. We’re happier at the more technical end of modernisation and leave the basics to the mass market consultancies.

Super-scale data is part of everything we do
Data platforms and analytics come as standard when you live on the cloud. It goes without saying that enterprise-grade applications generate huge quantities of data. We also get you ready for machine learning and AI.

Excellence in integration ties it all together
We work at the sharp end of integration, where connecting systems together is demanding because of data volume, mission-critical demands or high complexity.
If you want to move a text file from accounts to purchasing, you could choose anyone to help.
If your application needs to process data from a million transactions around the world every second… you need 345 Technology.
We think this picture says it better…

BizTalk to Azure migration
Calling us experienced in this might just be an understatement. Many of us cut our first, real integration teeth on BizTalk Server, so much so that we have been working with the BizTalk Migration Tool for yonks now, and that’s official.
