• Backend Web API .Net Core which uses:
o MVC architecture, Entity Framework core 3.1, Dependency Injection, Interface Segregation and Open/Closed Principles, Automapper, Fluent Validation for data models, LINQ for querying database (throughout IQueryables), Repository Pattern, Async Programming, Microsoft Identity for user authentication and JWT for user authorizations.
• Bug fixes on internal projects that uses AngularJs and ASP.NET Core Web API.
• Usage of GIT (gitflow) for versioning control and SCRUM-KANBAN for agile methodologies.

Develop and maintenance of clients SAP B1 Addons and windows services.
• SAP B1 Addons was made with SAP .NET SDK and these addons was developed according to the client’s requirements using SQL Server or SAP HANA SQL for the data persistence and also used Stored Procedures for querying data.
