ASP.NETSQL ServerOracleAjaxJavaScript● Developed web-based product lifecycle management applications sold to Coca-Cola, H.J. Heinz, McDonald's, Tyson, etc. Sales tripled during my tenure.● Corrected mixture of data access via O/R mapping and hard-coded SQL. Added a query builder to a proprietary O/R map. Ported the applications to multiple database engines. Simplified the API of the most commonly used library by two-thirds.● Introduced performance testing.

UI to simplify user interaction.● Mentored team members on refactoring, OO design, and JavaScript.

C#Image ProcessingUX Design● Improved the architecture of an application for scoring standardized tests. Doubled the same machine throughput of servers that processed millions of sheets a day. Redesigned the queue to allow horizontal scaling. Refined user interfaces via paper prototypes, iterative development, and WebEx demos for remote customers. Technologies included LEADTools, smart clients, web services, and workflow engines.● Proposed future directions for existing products and estimated costs of various alternatives. Mentored team members on design patterns, unit testing, multi-threading, and .NET libraries such as CAB and WSE 3.

C#C++SOAPSIPUX Design● Oversaw the development of six telephony products. Designed web services and applications for PBX configuration, TAPI servers, ACD servers, CTI productivity, VoIP phones, call accounting, and call centers.● Restored confidence in release dates and software quality. Finished a product that had languished for 3 years. Improved architecture and unit testing to develop similar-scale products on 6-month schedules.● Introduced peer review, test-driven development, spiral lifecycle management, automated builds, and pair programming. Advanced the department from SEI CMM level one to three.● Specified new products and features. Increased stakeholder feedback via detailed specifications, prototyping, and iterative development. Assisted sales presentations.● Assessed technology trends. Migrated development to .NET and C#. Adopted SOAP, NUnit.● Architected systems and contributed in every phase of development. Designed and coded shared libraries and high-performance servers. Wrote C# assemblies for RS-232 I/O, socket services, TAPI, CSTA, security, etc.● Improved user interfaces through goal-centered design. Implemented views with .NET Windows Forms and ASP.NET.

Machine LearningJ2EEJavaC++JavaScriptCRMEAIUML● Shipped a J2EE product that personalizes web site content for individual visitors. This eCRM tool was used to implement support sites that reduced costs for customers such as Canon USA. ● Developed an EAI product that provides XML interfaces to disparate systems such as Oracle ERP and SQL databases.● Estimated schedules and directed peer reviews for a team of eight engineers. Met development dates on two major and two minor releases.● Mentored team members on object-oriented design (OOD), multi-threading issues, network programming, GUI design, internationalization, and design patterns.● Trained support staff on troubleshooting the products and consultants on developing custom applications using the products. Presented conference talks and assisted sales to generate interest in the products.● Designed overall architecture for three products. When requirements changed (delaying one project), five developers collapsed the schedule by building interdependent modules in parallel. Due to solid interfaces, integration took only three weeks.● Designed a JDO-like (Java Data Objects) persistence layer to allow the transparent reading and writing of objects to a relational database. Allowed independent development of Java/C++ object models and their backend schemas. Class implementers simply mapped member collections, objects, and primitive fields to database fields and then delegated database actions to the API. The API handled tables mapping to more than one class and classes mapping across multiple tables.● Designed a personalized content management system. Exposed the module to web site developers via custom JSP tags (similar to Jakarta Struts tags). Due to the tag interface, no programming was required to personalize web sites. On requests for content the system used profile information to return the most appropriate content item for each individual.

C++SQLJavaScript● Documented designs with Unified Modeling Language (UML) diagrams. Simplified documentation using TogetherSoft’s Together/J and javadoc.● Proved correct behavior and uncovered flaws in third-party libraries by building unit tests with JUnit. Reduced QA bug counts to half the count for other groups in the organization.● Tuned for performance and analyzed load test results. Reduced the creation of little objects, refactored code for superior multi-threaded speed, and minimized network traffic. Tripled the performance of the most heavily used modules.● Wrote build scripts and oversaw configuration management. Builds resulted in InstallShield and Unix install programs ready to run.
