Northtech are tech savvy in Azure and Cloud Infrastructure. They provide great architects who can design infrastructure of any level at ease. There infrastructure diagrams are so good that going through that one can understand the whole infrastructure very quickly. I have a very good experience working with them on setting up complete infrastructure in Azure from scratch. This includes almost all the services provided by azure in most optimised way one can ask for. There work on performance optimisation of infrastructure is second to none and the way they captures requirement and bring those to live is amazing.
