The project team has achieved:● Successfully migrated the one of the intranet applications (which plays critical role in client's infrastructure) + public web portal from on premises environment to Azure, including full application revamp to avoid typical Azure migration issues such as dealing with MSDTC, splitting application on services to isolate code parts which can't be migrated to the Azure webapp service, introducing asynchronous execution tasks using Azure web jobs ● Performance improvement and introducing monitoring solution (Dinatrace) to the migrated applicationsWas as a backend/fullstack developer in the one of the Adviser Intelligence project development team. As a member of the team I ● Actively participated in the knowledge transfer process from the previous project development team● Was a part of the team which established the new technology stack using Microsoft Azure, Service Fabric, Nginx● Developing Insurance Tool/CAP modules including database schema design, implementation of data access layer, developing client UI components using AngularJS/ReactJS/Typescript● Performing code review, refactoring and unit testing of all levels of the application
