Identify, influence selection of and manage vendors / contract development.Administered and maintained an IT infrastructure consisting of 15 server instances in physical and virtual (AWS) environments (2/3 Linux/Unix and 1/3 Windows server), servicing a membership of 30,000 and a staff of 30 - 40 for this not-for-profit SMB association. Delivered technology projects and solutions.✶ Migrated crs.com onto a modern CMS platform integrating with 3rd party and legacy systems. --- Supported and managed over 4000 hours of contract development. --- Developed, tested and executed the re-launch procedure for crs.com without downtime. --- Maintained and enhanced custom integration HTTP API after initial contract development. --- Established and maintained (pre)/production environments✶ Delivered data integration solution interfacing a 3rd party Websphere MQ system --- Zato (Python, Redis and Postgres), AWS (EC2, Ubuntu LTS AMI) --- Established and maintained (pre)/production environments. --- Extended CRS HTTP API to facilitate integration. --- Produced solution with Talend ETL (Java) to prepare data for initial synchronization / resync --- Initiated and supported the contract development to complete the project.✶ Implemented data and distribution solution for “Find a CRS” iOS mobile app --- Talend ETL (Java), SQLite, Linux, AWS services (S3,IAM,Cloudfront CDN), S3CMD, boto --- Extract and de-normalized member data set Technologies (in addition to previous roles): Zato, AWS (EC2,S3,IAM,Cloudfront), Talend ETL, Nginx, Apache, SSL, PHP-FPM, PHP, Perl, Drupal, Drush, Git, Atlassian (Confluence,Bitbucket), MySQL, MSSQL, SSMS, SMTP, Samba, Baracuda SSL-VPN, Avaya, PHPMyAdmin, Piwik, Mediawiki, JVM, Tomcat, Apache Solr, Windows 8, Office 365, Cisco Meraki

Principal Network - Systems Engineer of a heterogeneous environment (Unix, Linux, Windows)✶ Migrate ~40 user mail boxes from on premise email system to cloud hosted Zimbra freeing up resources, perform the dns cutover.✶ consolidate total BIND servers by 50% and improve DNS cohesion. AD DNS forwards to BIND authoritative and recursive servers leveraging TSIG to ensure proper zone SOA context is transferred on update e.g. crs.com internal recursive vs crs.com authoritative. Bind servers forward to OpenDNS. Add lookup zones for authoritative AD DNS.✶ resolve smb network file sharing issue. Users reported inability viewing new files or file updates in network file shares. Windows 2003 DFS replication ignored open files, 2 users viewing same network share but on different targets. Resolution: have all users view same target. Configure Windows DFS namespaces and Replication maintaining redundancy to resolve issue where clients had been configured to choose a target rather than set preferred client target and fail over to secondary target.✶ configure tiered filesystem permissions for shared and private department network drives, permissions and access control based on department and non-department staff security groupsTechnologies (in addition to previous role): Linux, OpenBSD, BIND, NFS, DHCP, PXE, TFTP, RDP, Windows 7, Zimbra, ESET Antivirus, rsnapshot, duplicity, AWS Import/Export, Bash, Cisco
