TECHNOLOGIES
Languages
Today in my daily job, I use latest C#, JavaScript (ES6) and latest TypeScript. In the past I aslo used languages like Delphi, and VBA for commercial projects; and Assembler, Basic and Turbo Pascal for non-commercial projects. As for my main language - C# - I started with version 6.0 (.NET Framework 4.6) thru version 7.0 (.NET Core 2.1) up to latest .NET. Thus, currently I work with the latest version 10.0.
Frameworks/Libraries
Backend development: Currently I work with .NET 8; but I have wide experience with .NET Core since version 2.1 up to .NET 6. Frontend development: depending on the project, I work with React with Redux or React with ContextAPI. Mobile development: React Native for iOS/Android. CSS frameworks: I have experience with Bootstrap, Materialize, Bulma, and Material-UI (MUI). Currently I mostly work with MUI v.4.
OR/M & Databases
I have started with Microsoft Entity Framework and did one project; now in current projects I use Entity Framework Core. Depending on the requirements, I also use lightweight OR/M like Dapper and use Microsoft SQL and Transact-SQL (T-SQL) when necessary. I have experience with both Microsoft SQL Server 2022 and Azure SQL Server. I have also some experience with NoSQL like Azure CosmosDB and Firebase.

I have experience with Azure Cloud Services: App Services (PaaS), Azure Storage, Azure Redis, Azure Key Vault, Azure SQL Server/Database, CosmosDb (NoSQL), Azure WebJobs in App Services, Azure Functions (C#), Application Insights, Azure Containers with Docker images. Due to mobile application development, I also have experience with Google Cloud Platform (GCP).
