For an aerospace subcontractor I joined an Agile team collecting, homogenizing, and reporting manufacturing work-in-process for numerous dissimilar product lines and production sites.• Implemented ETLs via SSIS w/ C# components, extracting data from Oracle, Teradata, SQL Server, flat files, FTP, and web services.• Developed forecasting app to better predict tool and machine load times.• Traced and tuned production SQL Server databases.For a designer lighting manufacturer I automated an LED color mixing process that combines fixture choices, LED component specs, proprietary color matching algorithms, and cost-conscious inventories to produce circuit board order instructions.• Developed with C# and Razor, utilizing RazorEngine to produce highly portable HTML+CSS documents.• Injectable DLLs define interfaces, storage, proprietary mixing logic, report generation, user interface, and automated unit tests.For a public utility:• Upgraded storage components of an occasionally-connected-application (OCA) used by field service engineers to locate underground gas and electric. Performance improved as much as 10x on slower hardware.• Developed ETLs to integrate data from SQL Server, Oracle, FTP, flat files, and Microsoft’s System Center Configuration Manager (SCCM).• Developed Windows services with C# to facilitate ETL of maps and associated data from SAP and other sources into ImageSite DMS and Tensing GIS.• Migrated datacenter SQL databases from 2008 to 2012.For a renewable energy equipment manufacturer I helped design and lead the development of an IOT system to monitor and control renewable energy systems.• It monitors individual system performance and manages networks of larger systems.• It bridges communication between modern business systems and older ModBus devices.• The cloud-based solution included C#, ASP.NET MVC, hosted on Azure.• I co-authored device-to-cloud communication & security protocol, and implemented the server side code.

Leverage Review is ADI's primary customer-facing suite of tools, facilitating document review for civil litigation. It is a SaaS deployment. I helped develop and maintain all major versions the app's database, middle-tier, and web components as one of the longest-standing members of this diverse team.• Built a federated search engine to satisfy customers' desire for complex search queries. The data model and WCF service support deep nesting of filters, set expressions, and document relationships. A web UI lets users drag and drop filters, visually building and grouping sub-queries into parenthetical expressions. Results are sorted, faceted, and can be refined or saved for later review.• Developed custom controls to support complex web designs, like the one above, without page loads or flicker.• Improved build quality and stability by implementing TDD, automated unit tests, and continuous integration builds.• Increased code quality and readability by adopting Paired Programming. Perpetual collaboration and code reviews also lead to sharing of technical and domain knowledge, strengthening all team members.• Improved project visibility and adaptability by implementing the Scrum framework for Agile development.• Provided data modeling, design, and coding on all SQL Server object types.• Investigated and resolved SQL Server performance issues in both lab and production environments.• Reduced average UI response time by 90% for the only customer-facing product in 2003. This solo accomplishment was achieved by introducing new caching procedures and DHTML.ADI's Data Services team requires custom tools for moving, manipulating, and reporting on petabytes of customer documents, text indexes, and databases.• Developed ETLs with dynamic end-points for terabyte-scale databases containing hundreds of tables.• Developed stand-alone and 3-tier apps for data manipulation, grid-computing, and configuration control.

In this single-client arrangement (with WebNetwork Inc.), my focus was SQL Server database architecture, development, and tuning, plus ASP (classic), HTML, and Javascript development for the purpose of delivering small, cheap, e-commerce solutions.

SQL Server database and ASP (classic) web development.

Multiple consulting roles, primarily as a vendor at Microsoft's Internal Tools Group, working on several projects. Primary focus was SQL Server development, plus some C Windows forms application development. Also served as ASP and SQL Server developer internally to Best Consulting.

Testing Windows Forms based user intefaces. Testing of SQL stored procedures, triggers, and views. Developed automated testing for all of the above.

C programming (DOS and HPUX) of custom user interfaces and Oracle databases (HPUX) to track manufacturing work-in-progress, provide work-flow planning, and manage parts inventory. Included barcode printing, scanning, security, dissimilar-systems integration, and lots of hair pulling.
