Stared a new organization called the Nexus which is focused on reducing and eliminating third-party risk by developing superior in-house solutions.

• Participated in the entire release life-cycle of the Hinge reboot. From the initial product inception to the first release and beyond.• Designed and implemented globally load balanced Kubernetes clusters. These clusters service all the API traffic for the app. • Created a fully automated deployment pipeline (Commit->Test->CI->Deployment). Developers can tag branches which will create docker containers and deployment them safely in AWS. Built in Go using Consul at first, then transitioned to Amazon ECS.• Created Microservice Architecture: Application config and service discovery is managed through Consul, HTTP traffic is routed through Fabio and gRPC traffic is handled via Consul DNS. Service communicate via protocol buffers/gRPC or HTTP/JSON.• Created performance-critical portions of the architecture with Go based mircoservices. Reduced TCO further by replacing Python services with Go.• Created the entire backend in one month for the Hinge Matchmaker stand-alone product.• Docker Lead/SME: Brought in Docker to replace Chef/Ansible configuration. All developers now have a complete working environment they can spin up via Docker Compose. All Go-based applications are managed via AWS Container Serivce, while the Python based docker containers are managed via a home-grown solution I wrote.• AWS Lead/SME: Replaced entire Heroku infrastructure with a complete AWS solution. Implemented and manages over 15 separate AWS solutions from EC2 to RDS to CloudFront. All managed via CloudFormation.• Brought Google's Deep Learning tool TensorFlow into the recommendation service. Machine Learning is done live and recommendations are served in real-time.• In-House Penetration Tester and Security SME

• Built and maintained the Enterprise Chef servers and 300+ nodes attached to them.• Responsible for team’s security and penetration testing.• Built Spacewalk in-house and brought all systems under management. Security patches and testing are done in hours not days.• Implemented and evangelized DevOps principles across many areas of the organization. As a result, all servers are managed with Chef (Berkshelf, kitchen, foodcritic, etc.). Development life cycle now begins in Kitchen/Vagrant vs. a dedicated dev environment in the data center. Deployment is done via Python/Fabric scripts. They are repeatable and tested via Jenkins.• Eliminated legacy in-house RPMs by converting all functionality to Chef cookbooks.• Created data pipeline from production systems to backend processors. The flows were built with Flume/Kafka or ActiveMQ where needed.• Key decision-maker in moving customer facing applications into AWS and closer to the end-user via DNS geolocation. Globally scaled systems to handle over 70M actions per day• Reengineered the real-time monitoring system in influxDB/Graphana.

• Provided Tier 1 support for the organization. This covered a mixture of physical and virtualized servers running mostly RHEL clones (Oracle Linux and CentOS).• A part of the on-call rotation which monitored and supported 1000+ Xen/KVM/AWS/Physical instances across three collocated data centers and three AWS regions• Overhauled a key transaction system to respond in under 50ms, down from 2s which the legacy systems were built to handle initially.• In charge of upgrading older Xen-based servers to KVM with zero downtime for associated services.• Maintained and extended an in-house and custom-built RPM repository to manage legacy code. Implemented newer code deployments and server provisioning with Chef. Both in-house and in AWS• Survived Superstorm Sandy with a tethered Android phone and laptop, all customer-facing systems remained up throughout the crisis.

• Responsible for all Linux administration, both on-site and in the cloud (AWS & Rackspace/Slicehost). Server management via Puppet and Fabric. Backup administration with rdiff-backup and various in-house scripts for database backups.• In charge of researching and recommending efficiency, policy and process improvements to all aspects of the IT Department. Wrote policy for desktop, server and mobile security.• Oversaw code deployment to production systems via Python/Fabric. Also supported developers working in the testing/demo environment.• On call 24x7x365 for all websites and Linux servers.• Migrated key ecommerce systems from an unstable hosting provider to a load balanced and redundant solution in Amazon’s cloud (AWS).• Updated company from PCI DSS v1.2 to PCI DSS v2.0. Oversaw monthly vulnerability scans. Placed in charge of company’s overall PCI compliance• Completed SANS Security 560: Network Penetration Testing and Ethical Hacking course. A detailed and rigorous course on professional and ethical penetration testing.• Performed penetration test of web services using current modern attack vectors and methodologies. Reported findings to CTO and VPs.

• Responsible for all Tier 1 Linux support on campus and oversees Tier 2 & 3 Linux support personnel. Part of on-call shift rotation responsible for 24x7 support of all servers (450+).• As the local RHCE, responsible for all Red Hat Network administration, entitlement management and all Linux boxes in the server farm.• Migrated two proprietary Content Management Systems (EMPower and HotBanana) running on Windows/IIS/MSSQL servers to a new Drupal based LAMP system. This required not only system planning but also significant programming (PHP and Python).• Created a high-performance computing cluster of 40 custom blades. The cluster itself has 39 active nodes each running CentOS and is controlled from a central node via LAVA.• Main admin in charge of systems in the Amazon Web Services cloud. Connected Pace’s network with the cloud using a secure tunnel via an edge Linux server emulating BGP.• Built and maintained the Linux portion of the Disaster Recovery site. This includes replication of the web systems and student portal application.

• Director of Web and Systems Development; responsible for two direct reports that handle various programming projects as well as in-house training for our end users.• Responsible for HP blades, attached SAN and all system maintenance on various platforms.• Managed OS maintenance, upgrades, user management, backups, Perl/Python scripting, as well as database and system programming.• Functioned as the lead Linux Systems Administrator for the college. Often called into the Networking group for consultation on a variety of UNIX-like platforms.• Oversaw the migration of main web site from a Windows NT/IIS server to a LAMP environment. Including the training of all staff to use the new system.• Set up and maintain Single Sign On environment through LDAP, PHP and Shibboleth (SAML)• Integrated the wireless network with Steel Belted Radius & LDAP, as well as various minor systems into the Single Sign On environment.• Developed the organization’s first on-line election, and put many other internal services online
