About D55

Manchester-based D55 builds and runs cloud software and data platforms on AWS. It covers the whole life of an application, from early strategy and building through to monitoring performance afterwards. The team works beside client staff so they can run their systems themselves later.

Application development — cloud-native software, including rebuilding older .NET and SQL systems.
Data services — modern data platforms that bring together cloud, data and AI.
Managed services — ongoing running and tuning of client applications.
AWS audits and optimisation — reviews that find ways to get more from an existing AWS setup.
AWS funding support — help for clients applying for AWS programme funding.

D55 takes on anything from one focused use case to large cloud, data or software programmes for established businesses.
