I have worked in the Information Technology field for over 15 years and I create tools to automate day-to-day tasks such as to move information from SharePoint lists to SQL Server databases, to manipulate SSIS packages, to inventory servers, to conduct security checks of Servers and workstations, and just about anything else that needs automating. The tools that I create are based on technologies such as Powershell, JavaScript (browser and some node.js), and C# code.
Along with this I manage IT Infrastructure and I am keenly interested in server and application performance tuning. This has caused me to learn how to troubleshoot network related issues using network packet capture traces, to be able to use wait states to understand what is happening on a database server, and to do server side performance monitoring.
