About me

Hi, my name is Petr Nejedlý. I am a self-driven, Microsoft certified, freelance web developer with 20+ years of professional hands-on experience based near Prague, Czech Republic.

My field of expertise includes developing ASP.NET Web Applications (C#, WebForms, MVC, Razor, WebAPI, REST, MSSQL) using Git, TFS, or Azure DevOps with CI/CD, as well as working closely with my clients to help them with their digital transformation and providing a great digital customer experience.

Not only am I comfortable with things related to the development and delivering of a maintainable, easy to read code, I am also confident working face to face with clients throughout the entire project lifecycle. This includes, but is not limited to, presale activities, business consultancy, collecting business requirements, preparing analysis, wireframes, development, training, and also relationship management. I always go the extra mile and bring my clients some added value.

I am flexible, reliable, very precise, communicative, goal and quality oriented as well as exceptionally customer-oriented. I am very good at computing. I have deep knowledge in the field of algorithmization, planning, and realizing extensive application systems and services, knowledge of tools for system analysis and modeling creation.

Although I have been in this business for more than 20 years, I am not the type of person who thinks they always know best. I am humble and do not need to be right all the time. I am not a walking encyclopedia, but I know what to Google if needed. I can work well in a team, but also independently on my own.

Technologies and tools I am familiar with

.Net, .Net Framework, .Net Core, .Net Standard, .Net 5, C#, ASP.NET, ASP.NET Web Forms, ASP.NET MVC, ASP.NET Web API, Razor Pages, Blazor server, Blazor webassembly, REST API, JSON, SOAP, XML, ASP, IoC, DI, Autofac, Automapper, Dapper, Serilog, xUnit, SQL, SQLite, SQL Server, T-SQL, Stored procedures, TFS, Git, GitHub, Azure, Azure DevOps, Azure CI-CD, IaaC, Bicep, Azure Storages, Azure Functions, Triggers, Azure Service Bus, Windows Server, Visual studio, Jira, Confluence, Teams, Agile, Google Analytics, HTML, HTML5, Sitecore, Kentico Xperience, Kentico Kontent.

Recruit the attitude, skills can be taught!

I usually have very good relationships with colleagues and clients. Easy-going communication is a valuable asset I always handle with the greatest care.

If you feel that I might be a good fit for your team but you think there are some important skills missing on my list, I can learn quickly.

The way of work I am perfectly used to

  • Using Microsoft Visual Studio 2019 for the C# backend development.
  • Using Microsoft SQL Server Management Studio for the database logic development.
  • Using Github, TFS (Team Foundation Server), or Azure DevOps for code versioning and deployments.
  • Using Atlassian Jira or Trello for issue tracking.
  • Using Atlassian Confluence for writing documentation.
  • Following the Agile project methodology

What I am looking for

I am only interested in long-term projects with the possibility to work fully remotely.

My ideal job would be working for a mid-size digital agency based in the DACH region, in a small, agile, English-speaking team.

Looking for an experienced team?

I have a very skilled colleague/friend, Lubomír Laski. We can work well together as a team.
