    I have years of experience focusing on the messaging collaboration side of technologies including various versions of Microsoft Exchange and Microsoft Lync Server. I have worked as a lead engineer for major financial companies. I have over 8+ years of Powershell scripting experience. My vision is to provide my clients with enterprise knowledge and experience, give them the guidance for the right answer, and implement the best solution to ensure their day to day operations continue to run smooth. Recent Projects: 1. Create a secure, robust, and highly available Remote Desktop Services (RDS) solution in Azure leveraging Multi-Factor Authentication. 2. Migrate on-premise exchange to office 365 in a staged role out. This method included deploying Azure AD Connect for AD and password synchronization, as well as Exchange Hybrid. 3. Create Powershell script to parse mailboxes for emails matching specific criteria while tagging the email with a flag. This was done leveraging EWS API. 4. Move Sharepoint 2013 farm from using Windows authentication to Active Directory Federated Services (ADFS). This involved building out a redundant and secure ADFS environment in Azure leveraging multiple subnets (DMZ / Private), Web Application Proxies, and Azure Load Balancers.
