DotNet Ecosystem As a .Net specialist, I've engaged in projects utilizing C#, Blazor, .Net, and .Net Core. My solutions in this domain are characterized by efficiency, security, and scalability. Blazor Expertise Blazor, as a revolutionary framework for building interactive web UIs with C# instead of JavaScript, has been my forte. I've been at the forefront of utilizing its components, dependency injection, routing, and other features to create SPA (Single Page Applications) and web apps that are fast, responsive, and intuitive.

By capitalizing on Angular's powerful CLI, Ivy renderer, and RxJS, I ensure that the applications I design are both high-performing and user-centric. Drawing upon the versatility of NestJS's modular structure, its integration with TypeScript, and its embrace of decorators, I've been able to create backends that are maintainable, testable, and in harmony with modern API architectures. Totally, I am proficient in AI, Mobile, ASP, Python, Angular+Nest and also, Sure I provide high quality products.

    Responsible senior developer focused on Java(Kotlin) and Swift. I love the process of mobile app ideation and creation, that's my passion. Have been developed Android/iOS mobile applications for 7+ years, and my creatures include many differenct projects with diverse areas of focus, such as social media, lifestyle, food delivery, taxi booking, business and productivity apps etc. Over the past two years I’ve been contributing on android enterprise apps development for some companies. My specialty is Android firmware customization. I have full knowledge of architecture and principles of AOSP. Swift is familiar with me too, though unfortunately I was only 3rd place on Swift competition "iOS Development course 2017". My skills are: Android firmware customization, Android Studio, Java, Kotlin, Android SDK & NDK, Xcode, Swift, Firebase, RESTful apis, react-native with Redux and React.js, etc. My goal is getting glorious experiences with great cool clients through long-term complex jobs and projects to gain the top level all over the outsourcing world. Let's start to make surprising products together. :)
