    Greetings! My name is Sergii, and I’m a Xamarin Certified Mobile App Developer with more than 6 years of experience. I started my way in web and mobile development back in 2012 as a Casual Game Developer working for FIVE-BN (Alawar Division), and gathered some beneficial knowledge on how to create game logic, optimizing game performance, game deployment, and bug fixing. Later on, I have worked as a C# Developer in SoftReactor LLC, where I’ve gained and polished my skills related to ASP.NET Core, C#, MySQL, WPF, XAML. At almost the same time, I’ve started my own company - HeadWorks, where till present days my team and I have been creating web, mobile, hardware (embedded) projects, helping other companies to implement and convert their ideas into reality. In 2014 I’ve discovered Xamarin and incorporated it into what I have been doing - cross-platform mobile applications for iOS and Android. The tech-stack and skills I have acquired: - Cross-platform mobile app development using Xamarin: Xamarin.Forms, Xamarin.Native (Android, iOS), MVVM, Prism, MVVM Cross, MVVM Light, MVVM Fresh, ReactiveUI, AJAX - Creating complex enterprise-level custom solutions using C#, C++, MySQL, ASP.NET MVC, .NET Framework (CLR), .NET Core (CoreCLR), .NET GC, Azure, REST API, Web API, Google Maps API, Twitter API - Front-end development: HTML, CSS, JS, Angular - Facebook SDK, Visual Studio - Version control systems: Git, Github, SVN - iBeacons, Eddystone (estimote, kontakt.io) - Payment processors (Stripe, PayPal, Apple Pay, Webmoney, Yandex.Money) - Analytics and crash analytics (HockeyApp, Microsoft Insights, Firebase) I have recently started acquiring new skills on Objective-C, Swift, Java, Xcode and am planning on concreting the knowledge in the future. I’m open to everything new in the world, love to learn and prove myself, so all your queries and projects are greatly appreciated, and I’m ready to support you around the clock. I’ve been working with both individual clients, private and public companies (enterprise clients) and have helped them to bring their business ideas, thoughts, projects into life. Hesitation is the enemy of success, so send me the message, and let’s get your project into shape!

    Software engineer/architect with nearly 20 years experience with .NET, SQL Server, general web development, and software lifecycle management. I have been a senior developer, lead developer, supervisor, and architect. I have contributed as a technical reviewer, written articles for InfoQ, and spoken at code camps across the United States. I've been keeping up to date with .NET, starting with the 1.1 Framework, through .NET 6 today, and through this time I've worked with both C# and VB, WebForms, MVC, Razor Pages, Blazor WebAssembly, Entity Framework, WebAPI, ADO.NET, SOAP Web Services, dependency injection, cryptography, and more. On the web, I've worked with Angular, jQuery, Bootstrap, SCSS, Materialize, and WebPack. For databases, I've mostly worked with SQL Server, with some work in Oracle, and I've been exploring DynamoDB and other NoSQL databases. My focus has always been on quality, but speed is also very important to me. Working in the state government during COVID, I've had to build quality web applications quickly, including testing registration, business attestations, reopening requests, and complaint management, all with short deadlines and high visibility. I've always been up to the challenge.

    Hello! I'm a Senior ASP.Net Full-Stack Developer from Prague. My career as a developer started in 2002 during my study in the university. Since that time I checked roles of developer, team lead, architect and even project manager. I used to work in such world known companies as Monster.com or Barclays, had chance to participate in big enterprise project development using best practices. My main focus was always put on Microsoft .Net and related technologies but for several years I'm also using Angular. Besides web development, I have experience with desktop development for Windows using WPF. Together with my colleague we founded a company named Stantum s.r.o., and an agency here on Upwork. With its help we're able to take care about mid-size projects requiring a team. And here is a short list of technologies I have experience with: • OOP and System Design, UML • Design patterns - those from Gang of Four and from Martin Fowler • Asynchronous and multithreading development using TPL • Rest API design, architecture, implementation and integration • WCF and WebServices • GIT (github, bitbucket), TFS, Perforce, SVN and CVS version control systems • .NET / .NET Core C# • TypeScript • JavaScript • HTML, CSS/LESS/SASS • JSON, XML, XSLT, Serialization/Deserialization • ASP.NET MVC / Web API • ASP.NET Core • Angular 5 - 9 • React (beginner) • Bootstrap, Angular Materials • Email integration (custom SMTP) • SignalR • Microsoft Azure (Azure SQL, Azure AD, Azure Storage, Application Insights) • Entity Framework - DB-first, code-first and model-first approaches • NHibernate • LINQ and Dynamic LINQ • Database architecture and optimization: Microsoft SQL/T-SQL, Oracle, Postgres, MySQL • .NET Desktop - WinForms, WPF, UWP • Prism, MVVM Light • Telerik and DevExress frameworks for WinForms and WPF • T4 templates - reach code-generation experience • Test frameworks - NUnit, XUnit I love programming and know how to create successful projects, both green field and based on existing code.

    - 15 years of commercial expertise in software and database development. - Strong expertise in development utilizing the Microsoft .NET Framework ( ASP.NET, WebAPI, desktop application, windows services ). - Strong mathematical background (algorithms, modeling, numerical methods). - Good experience at unit and integration tests development. - Over 10 year’s desktop software development using Delphi (client server application, windows services). - Over 10 year’s experience using Microsoft SQL Server (development SQL queries, stored procedure, query analyzing, database design and administration). - Good at application performance optimization (complex mathematical calculations, algorithms, multithreading, benchmarking, application performance analyzing). - Strong experience in object-oriented design and design patterns. Point of professional interests: - Math modeling (Data Science, Big Data). - Application performance optimization and analyzing. - Writing code similar in performance to C ++ in C #. - Advanced debugging. - Functional programming (F#). Additional information: • My pet project is benchmarks set to measure performance of different IO .NET methods. Allow quickly measure IO operation and produce report for specific environment. • Was a speaker at several technical meetups: .NET Community 2021. .NET Meet up - Topic: From POC to high - performance .NET Application. - Summary: Often, in the process of software development, a prototype is first made to test some idea or model. However, it may happen that the execution time of the prototype makes it’s usage not possible. There are many best practices for writing high - performance .NET applications, and we will look at how they will work in practice and what the effect will be of them. During the presentation we: a) research our prototype to see how fast data processing can be; b) define metrics and measurement conditions; c) select the necessary tools; d) find bottleneck and best practice to resolve them. By improving the application step by step, we will make sure that it can run in 173 times faster and at the same time reduce memory traffic in 84.5 times. .NET Community 2020. .NET Meet up - Topic: My .NET application allocates too much memory. What to do? - Summary: There are many options for solving this problem, and we will consider one of them using an example of an application from a real project. In this project, optimal memory usage by the application became one of the values for the product owner. In presentation, we: a) look under the hood of an application from a real project; b) define the metric for optimization; c) choose the necessary tools; d) find memory leaks and best practice to resolve it. We'll improve the application step by step and see what with simple analysis and simple best practice we can reduce total memory allocation in 32 times. .NET Community 2019. - Topic: Memory allocation and performance in .NET - Summary: Impact of memory allocation on .NET application performance. Dive into IL code to detect implicit memory allocation. We consider micro optimization to solve memory allocation performance issues. Presentation will be useful for .NET Developers who need to provide optimization for .NET applications.
