In 2 weeks we set up Scrum Team including Product owner, Scrum master, Developers. Simultaneously we made Customer Development steps to define the right business model. It was necessary to choose proper technology stack. From one hand it should enable fast MVP release with possibility of easy pivots, from the other hand support future scalability and new features production. We chose ASP.NET Core, Angular 6 (Clarity/Bootstrap, Plotly), PostgreSql, Amazon Web Services, Gitlab CI.
