    I have been programming for over 8 years and have over 5 years of commercial experience. My main area of expertise is web development with the focus on backend and infrastructure part. However, good knowledge of Python language allows me to also be productive in other types of projects. I have experience working with Python web frameworks like Django, Pyramid, Flask or Tornado. For my projects, I have been using both relational(MySQL, PostgreSQL) and NO-SQL(MongoDB, Redis) databases. I also feel confident with setting up project infrastructure. I have been using Docker for 2 years, can configure CI server (e.g. Gitlab CI or CircleCI) and work with cloud solutions like Heroku, AWS and Google Cloud Platform I was involved in a few projects that used webscrapping as a source of data, so I'm familiar with libraries like Scrapy, Beautiful Soup or Selenium. Thanks to my communication skills, I am also capable of taking a tech lead role. I can easily understand clients, choose the right technology and then translate their project vision into tasks that need to be done by the developers. Programming is not only my job, but also my passion. I really enjoy facing new challenges and helping clients to build their product.

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.

    You don't just need a website. You need a product that makes people want to stick around, whether it's a static site or a full-featured web app. That's where I come in. I have worked with over 200 clients (including Fortune 500 companies) on various platforms to put out their best work. Careful attention to detail and understanding of what clients need. I don't like to fit any business into a boilerplate application with a few modifications that "mostly work". My standard services include: - Front-end development (Typescript, React, Vue) - CMS (Strapi, Contentful, Prismic) - Pixel-perfect layout (Figma, SASS, CSS modules) - Clean, self-explanatory code using S.O.L.I.D., D.R.Y., and design patterns - Test-Driven Development - Unit testing (Jest / Unittest) - E2E testing (Testcafe) - Distributed solution via serverless functions - Cloud-based deployment (AWS, GCP, Heroku) If you'd like to find out more about me, you can find me on StackOverflow, GitHub, or through my website. I am looking forward to working with you.

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.
