• Lead technical design and implementation of automated production build processes for Immuta’s products. Utilizing technologies like RPM and mock to build production deployable operating system packages and Docker to create service containers for deployment to customer systems. Responsible for integration of new software features into production package and dependency sets.• Implementation of a product CI/CD pipeline for our software products. Utilizing tools like Jenkins and Puppet, maintaining and operating a build process that allows our software to be functionally tested nightly, per sprint tags, and in a promoted production- style environment in Amazon Web Services (AWS) and on Docker quickly and effectively.• Design, development, and implementation of internal tooling to aid in company self-service of operational tasks. Examples of this are implementation of Rundeck and Terraform to allow management/sales to quickly deploy customer evaluation environments and custom CA scripting to allow internal developers to generate client certificates for testing PKI in our product.• Production infrastructure recommendations (for on-premise) and implementation (for hosted environments) of tooling and system security configurations to meet various technical compliance regulations (NIST, STIG, HIPAA)• Responsible for growth and leadership of Site Reliability team and ensuring that DevOps practices are implemented across the various teams within the company from Applied Engineering and Customer Engagements to Product Development and R&D.• Oversight, design, and implementation of the customer support system at Immuta to provide customers with support when necessary on product implementations and ensure that all SLAs are being met.

• Lead technical engineer on teams across multiple customer projects and consulting engagements, providing ground up design and implementation of cloud systems based around various software technologies; to include, RedHat/CentOS 5/6/7, Apache Hadoop, Accumulo, Storm, NiFi, Kafka, Elasticsearch, OpenShift Origin, JBoss, Apache HTTPD, Nginx as well as many other open source and commercial products.• Implementation of systems based on various infrastructures; physical hardware from SGI, Sun, Dell, HP, IBM, Cisco as well as IaaS and virtualization technologies VMware and Amazon Web Services. Utilization of SAN and NAS disk technologies from NetApp, Fusion IO and DataDirect as well as configuring networking on Cisco switches.• Design, engineering, and implementation of integration systems using DevOps concepts to improve infrastructure development, testing and deployment for multiple projects. Technologies utilized include GitLab, Jenkins, Puppet Enterprise and Open Source. Building workflows for teams to build, commit, and merge Puppet code changes effectively from disparate locations.• Certified and vetted PuppetLabs Service Delivery Partner. Writing custom modules including custom types, providers, and facts for customer solutions.• Consultant for commercial clients building systems, solving technical issues, and training general administration concepts and methods for Hadoop solutions based on both Cloudera CDH, and Hortonworks HDP distributions.• Accomplishments include a 80% reduction in time to field for a distributed processing system based on many open source technologies; successful engineering of upgrade path and deployment of big data systems across the globe in a 9 month timeframe; complete management of system software configuration and hardened security parameters using Puppet on multiple projects where manual administration was done previously, resulting in significant reductions in management/administration costs.

•Integration lab technical manager for a large Army project. Led team of multiple administrators in engineering and maintaining VMware vSphere integration environments with multiple clusters, integrated SPARC Logical Domains systems and NetApp SAN/NAS infrastructure. This included maintaining Active Directory, DNS, enterprise tools (antivirus, backups, SharePoint documentation systems) as well as patches and upgrades.• Designed, tested and implemented in production a secure VPN client environment using Citrix XenDesktop to allow developers, integration team members and managers to securely access the isolated lab network from their desks, significantly improving productivity.• Scripted and automated manual processes using various languages (Perl, Batch) to improve build process execution. Built custom LDOM management system to quickly deploy and destroy systems. Coupled with our VMware Lab Manager implementation, this resulted in an 85% decrease in deployment time.• Improved communication in the integration environment by setting up lab messaging and email services and improving documentation.

• System administration team lead; coordinated tasks and projects for a small team of engineers.• Analyzed future and current release requirements for integration of a SOA-based system and developed a project plan utilizing all available resources to successfully achieve milestones for release periods.• Worked individually or in a small group of engineers on system issues to include day-to-day administration and integration projects on RedHat linux servers.• Held weekly team meetings to discuss and analyze the status of outstanding issues and resolve any problems that arose. Escalated issues that required more authority.• Correspondence with System Engineers and Account Managers to verify team tasks were relevant and aligned with customer needs and system design.

• System adminstration for NetBoss Network Management System integration lab; responsible for Solaris, Linux, and Windows systems.• Provisioned and "smoke-tested" all customer systems pre-deployment; physically assembled customer hardware, updated firmware and software tools.• Maintained lab services, including NFS shared storage, process documentation and built and updated Nagios monitoring solution to meet operational needs.• Built a custom backup system in Perl using redundant NAS hardware units, within a significantly reduced budget, which resulted in a time savings for backup and restoration of files. The system employed rsync and hardlinks to effectively store large timeframes of system files in easily accessibly media. Maintained all backups for the lab, including to NAS units and archives to DDS/DAT tapes.• Customized Solaris Jumpstart servers to improve functionality and reduce customer system deployment time.• Custom-build Windows Deployment Services system and VBScripts to automatically build and configure next-generation customer builds. Previously these builds were done with Ghost and manual post-configuration. This improved lab productivity by eliminating the need to maintain images and to run manual post-configuration.• Built a modular "smoke-test" in Java for the next-generation product pre-delivery testing. This allowed any administrator to test customer systems quickly through a common interface and extend the interface to add new functionality to the smoke-test when new features were added.
