You need a developer who can quickly and efficiently deliver quality work, be it new development, bug fixing or optimization. Here are some reactions from some clients I have helped. "Stefan knows his stuff. He demonstrated exceptional craft and knowledge, well beyond the development skills of many developers." - Mike U. - "Five star all the way. Great communication as we worked and he provided a very elegant solution. I'll be using Stefan again and recommend him to you." - Between Coffees Welcome to my profile. I am Stefan Olsen. I am a Danish senior software developer and solution architect, specialised in building business software. I am an Optimizely MVP and 5x certified Optimizely CMS and Commerce Developer. A highly motivated professional, I am always looking out for my clients best interests. These are some things I have done a lot: - Websites, webshops or portals based on CMS platforms like Episerver or Umbraco - Web apps based on ASP.Net MVC or ASP.Net Core - Web app frontends based on VueJS, ReactJS or similar Javascript frameworks - Windows desktop applications - Payment platform integrations - Email and SMS sending integrations - SQL Server queries and procedures - Integrations based on Azure Functions, ServiceBus and/or NoSQL databases - Profiling, measuring and optimization of .Net and SQL code If you are tired of cheap and bad developers, promising great work but not delivering on time or quality, then give me a try. Find out what quality work means. Regards Stefan O.

We delivered a slow site analyzing tasks to Stefan, to help us understand what preformance issues we have with our fairly large EPI installation. After a few questions and a few days we received a well organized report, with all the findings in prioritized order and with suggestions on how to solve our problems. He found several issues in different parts of our solution, from extensive queries, caching and code so. We highly recommend Stefan, and will bring him onboard in future tasks!

Stefan knows his stuff. He demonstrated exceptional craft and knowledge, well beyond the development skills of many developers. From the outset it was clear that he understood the requirements, as well as the potential issues we could encounter in the project. His communication was fantastic and prompt. I have my new favorite developer!
