    • Résumé of Larry A. Leonard Larry@LarryLeonard.net 1331 Blackland Trail Lawrenceville, GA 30043 404.432.5931 SUMMARY Detail-oriented senior database developer with five years experience with SQL Server, focusing on logical and physical design, query optimization, and performance tuning. Expert at creating/maintaining idempotent upgrade scripts for versioned schemas. Deep expertise with Microsoft's Visual Studio 2008 Database Edition (code-named "DataDude"). Other skills include: 15 years' experience developing high-quality Windows front- and back-end software for thick-client applications, mobile devices, and the web; creation of publication-quality documentation using Microsoft Office; and agile (Scrum) development. EXPERIENCE Senior Database Developer, Varec, Inc (an SAIC company), Norcross, GA (permanent: 12/2007 - 11/2009) Skills and Tools Description Visual Studio 2008 TEAM Transitioned database installation from hand-written upgrade scripts to using the Team Foundation Database Edition Foundation Database Edition (GDR 2). Created a "database model" consisting of the GDR 2, SQL Server schema's database objects, which allowed us to install/upgrade any database, regardless of 2000/2005, SQL Profiler, its current schema, to conform to the model with 100% fidelity. This eliminated the need to Enterprise Manager, write idempotent upgrade scripts by hand, saving us approximately 40 hours/week. Also Management Studio, Query used GDR 2 to create static analysis rules, unit tests, sample data generation plans, schema Analyzer comparisons, and data comparisons. Overhauled schemas to conform to best practices for normalization, referential integrity, and performance. Revamped all indexing, using clustered, non-clustered, composite, and “included” / covering indexes, improving performance while reducing database size. Modified existing upgrade scripts to be idempotent. Reviewed all design and implementation of 100+ table database for team of application developers. Performed advanced query tuning using: execution plan analysis; examining read and write counts; creating and updating statistics; re-writing to use sargable expressions; and adding/dropping appropriate indexes (clustered, non-clustered, composite, included). C#/ASP.NET, ADO.NET, IIS, Designed, created, and maintained C# code-behind pages to display web forms, which called AJAX, AJAX Control Toolkit our business logic assemblies. Used AJAX Controls Toolkit to improve client-side responsiveness and usability. C#/.NET Created and maintained assemblies that implemented business logic via a home-grown metadata layer through ADO.NET to SQL Server. Involved a half-dozen large assemblies and a COM+ application. Experience in debugging .NET issues such as wrong assembly versions in the GAC, or assemblies with the same strong name and version, but different GVID. Maintained CLR assemblies for SQL Server 2005 that perform complex calculations on large datasets. These assemblies referenced what Microsoft calls "unblessed system assemblies", which are not supported for use in SQL Server CLRs, and so required workarounds. CSS, XML/XSLT/XPATH Created XSLT files to transform XML data into HTML documents for display and printing using a CSS style sheet. Created a "debug mode" framework in the style sheet that changed the colors on the styles, and labeled each element with its y-axis value, to greatly speed development.
    • RÉSUMÉ OF LARRY A. LEONARD Senior Software Engineer, Cadillac Jack, Inc. , Duluth, GA (permanent: 1/2007 - 11/2007) Skills and Tools Description SQL Server 2000, Query Responsible for maintaining, upgrading, and tuning customer databases up to 200 GB in size. Analyzer, SQL Profiler, Created maintenance plans, backup strategies, and remote monitoring system. Resolved Enterprise Manager, SQL deadlock issues and performance problems. Standardized and normalized schemas, added Server 2005 Management indexes, constraints, and referential integrity. Wrote T-SQL scripts for both initial installation Studio Express and upgrades, and mentored team members. Performance tuned using PerfMon, Query Analyzer, and SQL Profiler. Windows Mobile 5, Pocket PC Using ASP.NET, created a POS system connecting Pocket PCs running Windows Mobile 5 SDK, Visual Studio .NET over a wireless network to a Windows 2003 server. When the Windows Mobile client 2005, C#/.NET, ASP.NET, application requested data from the server, a web service responded by querying a SQL JavaScript, HTML, AJAX, Web Server 2000 database. Services Server side: Wrote the web service's ASMX file in C#, whose methods were exposed by its WSDL file. Database access was done via ADO. Client side: Implemented the mobile application as ASPX pages with C# code-behind pages, a master page, and CSS. Users' input sent requests to the web service, then displayed the responses. Since "Atlas" (AJAX Controls) was not supported on Windows Mobile 5, I created the SOAP document by hand, and did a POST via an XMLHTTP ActiveX object. C#/.NET, WinForms, Wrote two WinForms applications in C# that supported downloading of only the new or Serialization, Multithreading, modified items from a collection of 50,000 resource files. Interop, MD5, AES, SHA-256, Visual Studio .NET 2005, Server side: The server application generated an SHA-256 hash signature for each file; the XML, XSLT filenames and signatures were then stored in a single XML document as name/value pairs. Client side: The client application checked for new/updated resource files on an ad hoc basis. First, the XML document on the server was downloaded and stored locally. Next, for each local resource file, the client generated a hash signature, and did a lookup for it in the XML document. If the hash signatures differed, the client downloaded the new/updated resource file from the server. Senior Software Engineer, Ipswitch, Inc., Alpharetta, GA (contract-to-permanent: 7/2004 - 11/2006) Skills and Tools Description SQL Server 2000, MSDE, Senior Developer for WhatsUp Pro 2005, 2006, and 2007, a network monitoring tool, using Query Analyzer, SQL Profiler, the "Scrum" agile development method.

    • RÉSUMÉ OF LARRY A. LEONARD Practiced at informal database refactoring, and familiar with formal database refactoring as described by Ambler and Sadalage. Advocate of using "extended properties" for documentation. Database Edition Expert at Microsoft's new Visual Studio Team System 2008 Database Edition (GDR 2), aka the "DataDude", which, for the first time, abstracts database schemas into separate "database objects" with "full fidelity". This allows the creation of database projects that are equal peers to application projects. "Full fidelity" provides correct and complete dependency tracking and object renaming. The output of the database project can be freely installed on any computer, and, using a difference engine, automates and formalizes the ad hoc comparison of the schemas and the generation of an upgrade script specifically for the target database: this results, with some custom data-cleansing SQL code, in database installations and upgrades that virtually cannot fail. This process eliminates the need for upgrade scripts. The Database Edition also supports a framework for automated unit testing (e.g., does stored procedure "x" still work, and complete in less than "n" seconds?), customizable static code analysis (e.g., "= NULL" is not allowed), and the generation of meaningful test data. Query Tuning Can read and interpret execution plans, Profiler traces, dynamic management views, correcting issues like non-sargable expressions, missing indexes causing table scans, use of cursors, etc. Database Performance Skilled at full database performance analysis and tuning, including:  Use of Profiler to check for table scans, most expensive (in total) queries, use of parameters.  Maintain set of PerfMon profiles for disk/memory/CPU/network monitoring to locate system bottlenecks.  Examining for normalization (and de-normalization).  Checking wait-state values.  Doing ratio analysis.  Reducing locking/blocking/deadlocking by choosing concurrency and isolation levels, and/or adding indexes.  Examining schema design (especially index design) and optimization (defragmenting, rebuilding, statistics). Security Designed SQL Server security objects such as principals, securables, permissions, roles, users, asymmetric keys, logins, server roles, etc. Tools Very experienced with Microsoft's SQL Profiler, Enterprise Manager, Management Studio, Query Analyzer, Performance Monitor, and SQL IO Simulator. Experienced with RedGate's SQLCompare, TOADSoft's TOAD for SQL Server, DBSophic's Trace Analyzer, and www.SqlInForm.com . Administration Performed tasks such as installation, configuration, data loading, backup/recovery, upgrades, creating databases/file groups/files/logs. Have several maintenance scripts that automate index optimization, doing DBCC consistency checks, etc. Proficient at selecting server-wide (sp_configure) settings, database settings (sp_dboptions), recovery models, collation, etc. Technologies Dates Tools Microsoft Visual Studio Database Edition 1/2009 to present Database Edition GDR 1 and GDR 2 ("DataDude") 2008 SQL Server 2008 8/2009 to present SQL Server 2000, 2005 7/2004 to present T-SQL, SQL Profiler, Management Studio, Query Analyzer ADO.NET 11/2006 to present Oracle 7, 8, 9i 11/1996 to 7/2004 PL/SQL, SQL*Plus, TOAD Sybase 12/1995 to 11/1996 Watcom / SQLAnywhere 11/1996 to 11/1998 PAGE 5 OF 7
