    As a Technology Specialist, my responsibility was to lead small data-centric projects and provide architectural and technical expertise to the development organization. As a Technology Specialist, my work included:• Leading the Data Management Competency Center (DMCC). The DMCC served as a community of developers interested in data-solutions. As lead, I was responsible for running monthly meetings, presenting content on emerging technologies, as well as leveraging the community to further the development of Server Insight.• Automated the creation of Global OCEO Client Revenue Planning Workbooks, eliminating weeks of error-prone manual data entry and validation, and reduced the production of over 400 Excel workbooks to a few hours. • My favorite part of my job: Mentoring 3 junior developers who were interested in advancing their competencies in SQL Server. • The evaluation and implementation of PAGE compression in our primary data warehouse. Using PAGE compression resulted in an almost 70% compression gain, and 50% improvement in index scan performance.

    Development Manager, Global Client Intelligence
    Deloitte May 2008 - May 2018

    As the Database Development Manager for Global Client Intelligence, my responsibilities included the availability and performance of GCI database systems. Much of this work used historical performance data collected and stored in Server Insight (see below) to identify, correct and monitor:• Server and database configurations to insure they comply with best practices. • Issues skewing performance data and resulting in inefficient query plans with unmaintained indexes and statistics.Using Server Insight performance data, we saw a history of excessive writes and in some cases reads were causing unacceptable stalls across all GCI servers. The consensus decision was to eliminate the disk sub-system as a bottleneck and then re-assess memory. In a two-phased approach, Global Client Intelligence:• Migrated all of database storage to new disk IO controllers and solid-state drives. This reduced disk-read times in our primary data warehouse by 75% and overall by 66%. It also eliminated storage from the overall performance picture, and clarified the justification for increased server memory.• Increased server memory on their SQL servers from 64GB to 128GB to address complex queries requiring large sorts that were the primary cause of the stalls in tempdb,Completed two significant new Server Insight features:• The Perfmon Metric Collector (and changes to the Server Insight Metric Warehouse).• In-memory Analytics using Analysis Servers (Tabular) which consumed over 45GB of historical performance data into a 4.4GB Anaysis Services (Tabular) IMDB.
