Petr Pelnar

Software enginner, web developer from Prague, Czech Republic

I am software engineer with over 10 years of experience on Microsoft platform. During my career I have worked as developer, architect and development lead on various projects, mainly for English-speaking customers.

I have had an opportunity to work with ASP.NET, WPF, ASP.NET MVC, legacy ASP, WinForms, Windows Phone and other technologies. I have very good knowledge of MS SQL Server and MS Azure ecosystem (websites, servers, storage and deployment).

I am great fan of IoC/DI frameworks and ORM mapping which I use for most of my projects.

For web-based projects I use CSS and jQuery as well as other Javascript libraries to get most of the user experience. I focus on responsive web-design.
