I determined the hardware and software requirements necessary to meet the demands of the new system, aligning with the organization's objectives. System data was analyzed to identify the essential hardware and software components to effectively meet user needs. I confirmed the stability, interoperability, portability, security, and scalability of the system architecture, ensuring solutions are robust and future-proof. By communicating with staff and clients, I gathered specific system requirements, converting these into technical specifications and solutions. In collaboration with engineers and developers, I designed and implemented enhancements for existing system components, improving overall performance and functionality. System operations were continuously monitored, proactively identifying and resolving current and potential future issues using tools like System Center Operations Manager and SquaredUp. I was instrumental in building and maintaining an enterprise Exchange 2016/2019 environment, securing a reliable and efficient email communication infrastructure. Additionally, I installed and configured MFA for server infrastructure, standardizing Single Sign-On (SSO) processes to protect access via remote desktop and console logins. As one of the two architects, I developed a highly available data center in a location geographically separate from our original site. Furthermore, I managed and administered Azure Active Directory (AD) and Azure Infrastructure as a Service (IaaS), optimizing cloud resource management and security.
