I have worked on many British and international projects. I have implemented a lot of Sitecore customizations, like custom pipeline processors, event handlers, custom events, remote events. I was preparing structure for templates, layouts and content items for multisite Sitecore implementations. I have investigated complex issues connected with Sitecore performance, event queues, improper configurations. I was separating Content Management servers from Content Delivery and designing load-balanced architecture for overall better performance. I was preparing optimizations using Sitecore caches. I was integrating Sitecore with external systems using Data Providers and Data Exchange Framework. For one complex integration I was preparing database replication on MS SQL Server. I have expert knowledge in Sitecore upgrade process,  using Razl, setting up fresh instances and refactoring old versions custom code. I have worked in designing component based Sitecore structure for best solution to Experience Editor.

I really like to contributing with Sitecore community so I share my work, such as modules and packages, and my knowledge - with this blog and community forum.

I'm currently working at Ethisys - Sitecore development agency which I'm co-founder.

  1. Greetings Radoslaw,
    I have downloaded and installed your solution to for the Dynamic Sitemap XML. Everything looks great and I believe it installed corrected, but when I publish my site I am not getting any new tags in the sitemap.xml file? Am I missing something somewhere? We are launching our site in 3 days and this must be resolved before launch ... I will tell you what I have done: I have set teh host node, I have included only the page templates in Sitecore that I want to be in the sitemap.xml but when I publish nothing is being added to the XML file. Please advise
