Professional Experience

Designed, developed, and supported software features for the GoldSim product (www.goldsim.com). GoldSim is a Microsoft Windows desktop application used to design, execute, and evaluate simulation results, via the Monte Carlo method.

• Performance Tuning -- Designed, implemented, and utilized a framework for GoldSim performance tuning. Isolated and resolved several outstanding performance issues, resulting in speedup of 2x to 1000x for many user-initiated actions.
• Distributed Processing -- Implemented significant redesign and enhancement of the GoldSim distributed processing module, which executes a single simulation on multiple processors. Achieved significant improvement in reliability, due to improved inter-thread communication.
• Technologies -- Simulation, C++, Visual C++, SQL Server, MFC, ATL, COM, OpenMP, VB Script, JavaScript

Designed and developed features for software services for Amazon Single Global Platform project, which manages content and navigation worldwide for all Amazon commercial sites.

• Data Modeling -- Designed and implemented new database schemas to support Amazon website services for content management and website navigation (browsing). Combined OLTP design with data warehouse and audit trail features.
• Content Management Service -- Designed, implemented, and supported the software services that manage, store, and deliver Amazon website content.
• Website Navigation Service -- Designed, implemented, and supported the services that manage the navigation structure for Amazon websites.
• Technologies -- Java, C++, Perl, Linux, Oracle, J2EE, JDBC, Servlets, SOA, Web Services.

Participated in research, design, and development of the SMC-3D application. SMC-3D is a scientific visualization and data analysis tool for near-surface seismic tomography.

• DirectX Graphics -- Designed and implemented interface for 3D hardware-accelerated graphics using DirectX.
• Web-Based Deployment -- Supported and enhanced browser-based application deployment architecture.
• Web Services -- Supported and enhanced a distributed computing application that used Web Services for communication.
• Technologies -- C#, .NET, DirectX, Web Services, Web-based deployment, SQL Server, Design patterns.

Worked on design and development of a web application that helps corporate clients manage cell phone costs.

• Performace Enhancements -- Made significant improvements, especially in the area of database interactions.
• Technologies -- Java, J2EE, Servlets, JSP, JDBC, Oracle, SQL, HTML, JavaScript, iPlanet, Tomcat, XML, XSLT.

Worked as webmaster, website designer, and kayak instructor.

• Certified Whitewater Kayak Instructor -- American Canoe Association.
• Technologies -- Java, J2EE, Servlets, JSP, JSTL, JDBC, MS Access, PostgreSQL, HTML, JavaScript, CSS, data modeling.

Worked as a software architect/engineer on the AMSI mortgage project, and as a construction volunteer (www.habitatcolorado.org).

• Mortgage Processing Web Application -- Designed the database schema and data access software for the AMSI mortgage processing application, which provides mortgage forms and information for Colorado affiliates via the Internet.
• Team Lead -- Data Tier Development.
• Technologies -- SQL, J2EE, Servlets, JSP, Struts, JDBC, PostgreSQL, UML, XML, XSLT, EJB, JBoss, Design Patterns, data modeling.

Participated in design and development of data mining products that use artificial intelligence techniques to predict customer behavior. Defined software development standards, approved software designs, and mentored developers.

• Artificial Intelligence Data Mining Product -- Participated in design and development of the APT Product Suite, which used AI algorithms to predict customer behavior for customer relationship management (CRM). Had primary responsibility for the APT database schema design: a hybrid that incorporated both data warehouse and OLTP principles.
• APT Product Performance -- Used both active (code refactored) and passive (code unchanged) techniques to improve product performance in production and test environments.
• Architecture Team Member -- Defined software standards, approved designs, mentored developers.
• Technologies -- Java, J2EE, Servlets, EJB, Oracle, SQL Server, UML, Design Patterns, MVC, JDBC, C++, stored procedures, performance analysis, data model design, XML, XSL, SOAP, CRM, artificial intelligence, data mining, ETL.

Designed and developed enhancements to the PV-WAVE and JWAVE products (www.vni.com).

• MOLAP Cube Data Visualization Application -- Acted as sole designer and developer for this application, which demonstrated data manipulation & visualization capabilities of the PV-WAVE and JWAVE products for the business intelligence market. This application was featured by VNI at Oracle Open World, 1999.
• PV-WAVE Language Kernel -- Designed and developed enhancements to the interpreter and the function library for the PV-WAVE computing language. Refactored PV-WAVE library functions to improve application performance.
• Data Analysis Portal Project -- Designed and developed the database schema and data access software for this project, which was used to create, store, access, and analyze statistics data through a web interface.
• PV-WAVE Database Driver Performance -- Refactored database driver code, resulting in vastly improved performance (10x faster). On Oracle, the final performance was faster than SQL*Plus for the same SQL query.
