Tip: Make sure to discuss the integrations your future software needs for our .NET integration architects to draft an integration plan. If required, our developers and DevOps experts will continue with delivering all planned integrations.
2. (Optional) Screening & interviews (2-5 days)
For a team augmentation model, we provide you with developers’ CVs and arrange interviews with the candidates you shortlist.
3. SLA preparation (2 weeks)
We set up communication between our developers and you and deliver the service scope steps that were defined in the SLA.
Tip: Feel free to list custom KPIs you want to monitor in your .NET project so that we can add them to our KPI set. We give you access to our log tools and send you regular progress reports to ensure full transparency of cooperation.
4. Cooperation launch (1-2 days)

Frequently Asked Questions
Do you support 'you build it, you run it' model?
Yes, we offer dedicated .NET teams ready to take full technical ownership of the project and be responsible for everything from planning and development to infrastructure setup and management.
What is the difference between .NET Framework, .NET Core and .NET?
In 2002, Microsoft created .NET Framework as a development platform specifically for Windows applications. In 2014, Microsoft introduced .NET Core, a cross-platform version of .NET that could be used on Linux, macOS, and Windows. .NET Core was also open-source and designed with cloud computing in mind. The name .NET Core was retained for versions up to 3.1, but the subsequent version was named .NET 5.
Who manages the project?
We have a strong full-scale PMO with ample experience in complex, large-scale .NET projects. The majority of our projects are managed by our in-house project managers.
However, we can also provide a dedicated .NET development team to be fully or partially managed by you. We minimize management efforts on your side by ensuring high transparency of the development process and proactive risk management.
