Over 30 years of contact center experience. Pivotal participant in many large contact center design and migration efforts. Cisco UCCE and Avaya are the best examples. Lately lots of 3CX,FreePBX and Asterisk assignments. Almost every call center change or migration requires a new recording. All of the recordings can be in the same voice making for a better user experience. We have invented a new scenario that allows us to provide our clients a Google TTS methodology. If the client can provide the text, we can turn the recordings around in very short order. We can do English, Spanish and many other languages. This is a very exciting technology shift that allows us to make the new recordings in minutes at at a very affordable price.

I am an IT professional with experience in several domains. I work approximately 25 hours per week for a manufacturing company, managing infrastructure, and allocate time to honing my skills within the freelance market. One of the managers I have worked with calls me a "Truffle Pig" meaning I enjoy rooting out problems and finding solutions. "Let's transform your IT challenges into opportunities. Message me to begin the conversation!" Key Skills: IT Infrastructure Management Cloud Deployment (VMWare, Hyper-V) Network Engineering (Cisco, EMC) Systems Administration (Windows & UNIX) Project Design & Implementation Troubleshooting & Problem-Solving Below is an overview of my background and experience. I provide services as an IT Systems and Network Engineer and Administrator. With over 29 years of experience spanning a wide range of skills, including project design and implementation, I have experience working in both Windows and UNIX environments. My background covers general IT knowledge, with ongoing efforts to expand my skillset. I have worked with various vendors, particularly those specializing in medical and enterprise systems. My experience includes troubleshooting, research, and providing support across different teams. Project Highlights: • Led deployment of private cloud and IT system upgrades; served as subject matter expert. Functioned as Systems/Network Administrator for a public health district hospital, responsible for setup, automation, and monitoring of a private cloud environment. • Managed transition from legacy systems to new infrastructure; deployed and administered monitoring and management systems; handled special projects, including testing and deploying new systems, addressing longstanding issues, and overhauling monitoring and asset tracking systems. Oversaw transitions to a High Availability “A side/B side/C remote BDR” Data Center design, resulting in improved system reliability and reduced manpower needs. • Served as consultant for a public health district hospital to deploy a private cloud. • Deployed and configured a private cloud based on Cisco UCS/EMC VNX/Hyper-V/VMWare VSPEX reference platform for a regional hospital. Collaborated with employees and vendors to complete the project and was later retained to improve existing IT systems (including SNMP monitoring, Syslog, Helpdesk, security, and maintenance automation). These changes enhanced network reliability and reduced management effort. • Managed cloud-based application development projects as project manager and technical lead. • Acted as Systems Administrator/Engineer for deployment and integration of cloud-based applications with mobile and local systems. Researched, selected, and integrated cloud-based products to create an IT services management solution using Autotask, N-Able, QuickBooks, StoreGrid, and Channel Online for an MSP provider. The final implementation addressed quoting, ticketing, purchasing, billing, and time management, involving collaboration with consultants and technicians for integration and training. • Oversaw replacement of existing PACS/RIS solution with RAMSoft PACS/RIS solution. • Coordinated with multiple vendors and providers to facilitate hardware removal and installation, as well as software integration across eleven vendors. Completion occurred on schedule and within budget, with minimal impact on office operations. Managed HIPAA meaningful use EMR and specialty procedure management system upgrades and deployments. • Led upgrade and deployment of multiple VMWare server solutions for specialty medical offices. • Solutions incorporated various hardware and software, such as Windows Server, Small Business Server, SQL, Linux, VMWare, Proxmox, Cisco hardware, Qnap, HP, Dell, and StoreGrid. Supported medical software including GE Centricity EMR and Practice Management, GMed GGastro, Maximeyes, Paragon among others. Determined optimal upgrade paths, reducing project costs while meeting client requirements. Utilized VMWare and redundant servers to reduce costs by more than 30%, maintaining performance and reliability. Delivered a complete solution with email server and backup/disaster recovery at lower cost compared to competitor estimates. Identified and addressed key performance bottlenecks to ensure responsive, reliable local and offsite backup and disaster recovery systems.
