    I've been working with WPF/MVVM for the past 10 years now, WPF.Core - 2 years, 4 years with UWP, 2 years with WinUI and MAUI, its not like "I've seen MVVM couple of times, I can work with it" - I specialize in it indeed. Few years with Silverlight and Lightswitch. Most of my work is LoB applications with MS SQL Server backend. Using all MVVM features in my applications, DependencyInjection, Navigation etc. Mostly working with Prism, but I also done a lot with MVVMLight, Caliburn.Micro and MS MVVM Toolkit. Writing clean, easy to follow code, which can be expanded later by another programmers. Building complete solutions from scratch, covering all 3-tier aspects - DB objects, services, clients, I've completed 30+ projects (mostly - LoB applications) and gained lots of experience with it. You can see some samples in my UpWork portfolio. Very good knowledge of the most popular WPF toolkits: Avalonia, Material Design, Telerik, DevExpress, Infragistics, SyncFusion. C# - since .Net version 1.0 Working with MS SQL Server since version 6.5, I'm very proficient with T-SQL. MS Office, VBA – since ver. 5.0 Good knowledge of Crystal Reports. Using Git, TFS. Agile development.

    🥇 Top 3% Freelancer with 10+ years of experience, having delivered 50+ projects with 100% success score, without even a single 1-star review, sounds impactful, right? 🔝 Let's jump into this ultimate success boat. ⏩ My Full Stack development skillset includes .NET Core, Angular, React, Node, C#, Blazor, ASP.NET MVC, and Flutter for mobile applications, which allows me to develop end-to-end systems that are optimized for performance, security, and scalability. Here is an overview of the languages, frameworks, libraries, and design patterns, I have worked with for the Back-end Development: ✔️ .NET CORE, C# (.NET 3.1 & .NET 6) ✔️ ASP.NET MVC & ASP.NET Web API (Entity Framework, SignalR, CQRS Pattern, Clean Architecture, Asynchronous Programming, Dependency Injection with Autofac/Unity, AutoMappers, Generic Programming, API development, Repository pattern, Razor Syntax, Web Pages, State Management through sessions & JWT based tokens, Logging with Serilog, Log4net etc, Error Handling) ✔️ BLAZOR including WASM and Server Side ✔️ API Development (ASP.NET Web API, .NET Core APIs, Node, Nest.js Framework, authentication & authorization using JWT Web tokens, Passport.js, Firebase) ✔️ Unit Testing (XUnit, NUnit, Selenium) ✔️ Cloud Platforms (Microsoft Azure, App/Cloud services, Redis cache, Service bus, Queues, SignalR, Azure SQL, App Insights, Azure Functions, Storage accounts, vNet integration, Azure DevOps, Google Cloud Platform (GCP), Amazon Web Services (AWS), Lambda, S3 Storage) ✔️ DevOPS (Continous integration & continuous development using Azure DevOps & Github Workflows) ✔️ API Integration (Google API's integration including Google Authentication using oAuth 2.0, Google Drive APIs, Google My Business APIs, Places, Google Ads, Google Analytics, Calendar, Youtube, Pub/Sub.

I worked my way up from Javascript and jQuery to Angular back in 2016 followed by Reactjs) ✔️ Web Design (CSS 3, Twitter Bootstrap, Tailwind, Figma to HTML, PSD to HTML conversion) I don't sit quietly if there's little activity at any given time. My inner self forces me to just learn, learn, and learn. A similar thing happened when I started my development journey with Flutter back in 2019. ✔️ Flutter (Stateful/Stateless widgets, Providers especially Consume/Select, ListViewBuilder, StreamBuilders, FutureBuilders, Flutter widget life-cycle, working with the data, Firebase & SqlLite, Shared-Preferences).
