The client is a fast-moving, international technology company, specializing in powerful, highly scalable Office 365 migration and management solutions. They enable their customers and partners to move quickly and seamlessly into Office 365 and later equip them with the needed tools to get the best possible ongoing experience with the service.

request background

Flexible way of managing subscriptions

The client needed an internal set of shared services, to provide them and their partners with an easy way to manage subscriptions and organizations in a flexible way. Management of multiple Office365 tenants was a rather complex task, so they had to look at multiple out-sourcing providers, taking into consideration the following aspects like speed of work, technology stack, libraries used, architecture and design patterns.


Complete system audit

There were many problems holding the solution back like lack of documentation and absence of fresh ideas. Moreover, the whole system contained many sub-products that needed to be audited, multi tenancy and tenancy had to be added, Okta had to be replaced with SSO.


  1. Create a core for a complete authorization and role management system from scratch
  2. Develop a management system for users, organization, and subscriptions
  3. Set up a library of universal access to different data sources


Perfecting the product

  • image .NET Core, ASP.NET Core, EF Core, Identity Server, Azure Clouds, AWS Clouds, Docker, DynamoDB, MySQL, MSSQL, RabbitMQ, React.JS
  • image 3 years
  • image 10 specialists

Since the first stages of delivering the concept of the new set of services, the client enjoyed the result and wanted to implement everything as fast as possible. A lot of time and effort was spent on the analysis and identification of the bounded contexts (Domain Driven Design) of initial deliverables. We had multiple teams of different sizes, based on the demand of the product, with individual tasks and skillsets: architects, senior and junior C# developers on the back-end, UI/UX frontend developers (React). All the work was coordinated, implemented, and released by leveraging Azure DevOps service.
