  • Headed design and development of highly successful products.
  • Worked closely with multiple business units to define requirements, develop and test the product, and roll out to production. Provided post deployment support and continuous improvement.
  • Implemented substantial user improvements based on observed in-the-field use and identified pain points.
  • Made significant improvements to complex products impacting 60K+ customers.
  • Identified, corrected, and tested deficiencies; improved work flow and efficiency with administrative teams.
  • Refactored Confidential -SQL code for significant performance improvements.
  • Modified the physical data model to improve concurrency and resource utilization. Implemented substantial user improvements based on observed in-the-field use and identified pain points.
  • Designed and developed a service broker queueing framework that allowed developers to easily utilize the asynchronous processing capabilities of service broker while abstracting away the complexities of dialog management, error handling, poison message, and logging. Made extensive use of XML schemas to ensure data met certain standards. Paid close attention to security and privileges to ensure no unauthorized use or possible data loss, and developed a set of procedures to allow developers to easily register their code, make use of the queue, and troubleshoot any errors.
  • Consistently worked closely with business teams and stakeholders to ensure my team developed a high quality, scalable, efficient product that satisfied all of the core requirements of the stakeholders while remaining feasible to implement under time and budget constraints. Frequently recognized by senior leaders outside of the development team.
  • Provided 24/7 production support for a clustered SQL environment, multiple IIS web servers, and FTP servers.
  • Directed deployment of AlwaysOn using two secondary read-only replicas in SQL Server 2012, 2014, and 2016.
  • Maintained production backups. Performed regular tests to ensure backups were restorable.
  • Anticipated and resolved issues through consistent monitoring of key server, instance, and database statistics.
  • Automated time-consuming manual processes with fault tolerant PowerShell scripts.
  • Assisted developers when designing data models to ensure a scalable, normalized physical design that helps to reduce potential concurrency issues and maximize page density for efficient resource usage.
  • Worked closely with storage admins and vendors to perform capacity planning ensuring necessary resources were available when needed.
  • Troubleshooting of database corruption by examining individual corrupt pages to ensure that when using the REPAIR ALLOW DATA LOSS feature, there was no actual data loss.
  • Led training sessions with junior developers to teach physical database design considerations, basics of SQL Server internals, performance tuning and optimizations, and development best practices.
  • Guided junior developers with comprehensive code reviews and design analysis.
  • Work with new developers to assist them in learning ISN products, practices, and coding standards.
  • Provided one-on-one mentoring with junior developers to correct performance issues. Worked to ensure that they understood why a change was made so that they would be able to both retain and apply the gained knowledge.

SQL Engineer



  • Key team member of an extensive performance tuning effort that led to the creation of over 1000 indexes, the development of an automated statistics update process, refactoring of hundreds of stored procedures, and resulted in a reduction of average daily timeout errors by over 90%.
  • Analyzed physical design to improve performance, scalability, and data integrity. Always considered SQL internals when creating a physical design being aware of row density, the potential for page splits, file group usage, and both horizontal and vertical partitioning strategies.
  • Created intelligent indexes, altered data models, and refactored code to yield significant performance gains on hundreds of bottlenecks.
  • Performed design and code analysis to identify and correct deficiencies and potential performance and concurrency bottlenecks.
  • Analyzed execution plans to identify query pain points and significantly improve performance.
  • Rewrote complex Confidential -SQL stored procedures to replace inefficient procedural based code with highly efficient, optimized set-based code.
  • Analyzed wait stats, deadlock graphs, and unfamiliar, complex Confidential -SQL code to analyze stored procedures with a history of deadlocks, plan, and implement solutions.
  • Studied performance tuning with Paul Randal and Kimberly Tripp in the SQL Skills immersion course.
