Fidelity Investments - SENIOR DATABASE ADMINISTRATOR Schiller Park, IL, 11/2012 - CurrentDATABASE ENGINEER Successful launch of The Elder Scrolls Online MMORPG, and The Elder Scrolls Online: Tamriel Unlimited MMORPG. Performed major role in the engineering and implementation of the back-end services utilized to make up Zenimax's exclusive mega-server technology. This included extensive server build-outs, configuration, and optimization within VMWare to provide a dependable, efficient, and scalable system for the game server to consume. Provided skilled scalability and HA methodologies using MySQL Master/Slave replication, MariaDB Master/Slave replication, MairaDB GTID based replication including multi-master replication, MaxScale, MySQL/NDB Cluster, and Linux (CentOS). Also versed with RabbitMQ's implementation and clustering. Provided Linux and disk optimizations commensurate with above data technologies. Created/maintained internal systems for administration of the back-end systems, including those utilized by Zenimax's exclusive mega-server technology. Created and maintained monitoring, alerting, and trending methodologies across various Data Services environments (i.e. Development, mega-server, etc.) incorporating various technologies and programming languages (BASH, Python) to provide a fast, accurate, and dependable monitoring/alerting/trending solution specifically tailored to our needs. These methodologies have been created to work with various existing products such as OpenNMS, Shinken, and Graphite, as well as provide robust alerting for triage. Created a systems management structure allowing for deployment of new systems; team contributor using SaltStack; Extensive implementation performed in AWS (i.e. EC2, SES, CloudWatch, etc.) Provide on-going support, consultation, and implementation. Also provide infrastructure and architecture support for new and existing systems.
Autodesk Inc. - PRODUCTION DATABASE ADMINISTRATOR Utah, IN, 01/2011 - 01/2012DBA operations in a global HA environment; create schema architecture, implement triggers, procedures, functions as necessary to complete tasks; optimize MySQL server via CNF tuning, Linux OS tuning, worked with System Administrators to tune disk and OS systems; Create clustering solutions as needed; write scripts as needed to accomplish maintenance or routine functionality (BASH, PHP, PL as necessary). Maintain uptime through failover and load balancing; Perform triage and disaster recovery during replication issues or cluster/node failure. Provide administration and support to developers for all database operations. Write an application to give MySQL health and metrics using PHP, MySQL, and AJAX (JS). Install, set up, and maintain backup solutions using Zmanda Recovery manager. Wrote an in-house backup solution with data retention for smaller products.
Miniclip - SOFTWARE ENGINEER/WEB DEVELOPER/LAMP ENGINEER City, STATE, 01/2011 - 04/2011Engineered Linux-Apache-PHP system to connect with an Oracle backend. The server environments: RH Linux on the production server, and Debian Linux on the development server each running Apache 2.2 and PHP5.3 Each installation involved adding build dependencies to the distribution, compiling and installation the Oracle OCI8 kernel module, and whatever modules would be needed for Virtualization, as Cloud services are planned at a later date. Developed an AJAX powered PHP application that would allow network topology and infrastructure information to be available to users. Information is presented in an interactive, data entry format as well as visual hierarchical representations. This system was designed to work as an enterprise application with an Oracle back-end, using Microsoft AD authentication. AD interaction is done using the PHP-LDAP library, and handled by the application. Created a wrapper class for interaction with the Oracle database server which encapsulated the database server's views and stored procedures (e.g DAL). Created class methods that utilized PL/SQL for SP functionality. AJAX implementation uses HTTP Requests from custom written Javascript functions, to server side classes, libraries, and functions written in PHP5. This entire application and its components were developed 100% from scratch and have no dependencies.
Miniclip - SOFTWARE ENGINEER/LINUX SYSTEMS INTEGRATOR/TECHNICAL SYSTEMS ANALYST City, STATE, 01/2009 - 01/2010Installed, configured, and maintained LAMP system using Dell Optiplex Server hardware and Linux OS - Apache, PHP, MySQL, Linux solution. Designed and wrote web application allowing user interface to CMTS and cable modem data. This would allow for users to view technical data and leverage this against stored billing and customer data, down to the CPE device level. Created the data architecture to warehouse the data retrieved form the network devices. Integrated collected data and existing corporate data via web applications, while maintaining corporate and customer informational integrity. Designed and wrote SNMP polling processes which collected data via solicited SNMP to CMTS devices, and to customer premises equipment. Used SNMP calls via PHP and parsed returned information. Polling process ran by CRON jobs which in turn ran PHP-CLI processes. These processes were written in such a way as to allow the polling system as a whole to be multi-threaded. Designed and wrote data warehouse system that stored collected SNMP information that could be queried against by users, and by the application for charting and reporting functions. Information parsed from the polling process would be sanitized and injected to the MySQL server database. Designed and wrote CVS export functionality for select data screens and HTML reports. Integrated Flash Charts library; Designed and created charts used for viewing selected statistics. Chart information was written in XML, which was created on the fly once retrieved from the MySQL database Developed a TELNET function that was software controlled, allowing automated TELNET sessions requiring no user input. This allowed backup data collection via Command Line Interface (CLI) commands on the CMTSes. This involved using the PHP-SOCKETS library to open a TCP/IP socket which was controlled programmatically. Designed and implemented basic status polling system via solicited SNMP which gave basic health monitoring to the applications using it. This system ran from a CRON job which executed the starting PHP-CLI process. Basic AJAX framework implemented using JavaScript and PHP. Mapping functions integrated into the application, written in PHP and JavaScript, and utilized Google Maps API v3.0 Provided functionality to allow the application to be server side processor for other languages such as C# and ASP. These were provided as basic web services, and tailored to the individual needs of the calling application. Performed troubleshooting on C# and ASP projects. Successfully performed program maintenance, and added new functionality to the ColdFusion intranet application used within the company; Created data processing functions that would synchronize/export data between MySQL and Oracle.
