Experience

Independent

GoodVies.com

2009 - 2010

• Created GoodVies.com to provide on-line registration services for martial arts events.

• Created custom shopping cart with encryption to show line item details when using PayPal credit card processing.

• Created back-end fulfillment using JMS from Glassfish by integrating with PayPal's Instant Payment Notification (IPN) to determine payment confirmation.

• Protected customer passwords with random salt and iteration based encryption using Jasypt for greater security.

• Designed and implemented database schema to support multiple events belonging to multiple directors using JPA provided by Glassfish.

• Created web front-end using Wicket web framework to enforce MVC design pattern.

• Role-based content displays additional site functions depending on the user's role.

• Implemented automated unit testing of database and web UI using JUnit and Wicket. Current count is 239 tests.

• Ported, web-based, Daga Tournament Software from JBoss (3.2.x) to Glassfish for use with web site. The resulting conversion along with minor Glassfish performance tuning, yielded an 8x increase in performance as measured with JMeter.

• Daga was successfully used in several major martial arts tournaments. Recently, this software was instrumental in completing a three day tournament, on time, after starting one day behind schedule due to various delays.

• Provided on-going technical support for both the web site and tournament software.

Senior Engineer

Bloom Energy

2006 - 2009

• System Administrator for XFRACAS and SigmaQuest software. Responsibilities included: managing user accounts, providing user training, and communicating with vendors to manage software upgrades and feature enhancements as company priorities change.

• XFRACAS – Failure Reporting, Analysis and Corrective Action Systems. Created multiple scripts in Groovy to provide functionality not included with this commercial software.

1. Scripts to convert a Windchill Bill-of-Material (BOM) in .xls format to an XFRACAS BOM ready for upload, generate a subset BOM for XFRACAS using a separate spare parts list, analyze the BOM for duplicate product numbers, and output the BOM as an indented tree in HTML format to better visualize the product structure. These scripts provided the bridge between two closed-source applications allowing them to be integrated.

2. Script to automatically distribute personalized reports to individual group members as a URL link via email on a weekly basis. This report promoted greater XFRACAS usage because it served as a reminder and saved each engineer the time of going into the web application in the first place by indicating how many incidents are assigned to him/her.

3. Script to automatically generate a customized report for the Quality and Reliability team delivered as a URL link via email which displays at-a-glance information on incidents created during the past week. The advantage of this single report is that it directly queries the database to consolidate specific categories. To provide the same data through XFRACAS would require multiple standard reports and include extra information not pertinent to the team.

• SigmaQuest (SQ) - Worked with end-users from other departments to understand their needs. Designed and implemented a solution in Groovy leveraging the XML capability of SQ (SigmaSure and Genealogy) to satisfy those requirements.

1. Script to automatically convert grading reports wrapped in SigmaSure XML into Genealogy XML and load them directly into the Genealogy database via HTTP post. First trial run of 1000 reports resulted in only two failures. This script runs hourly and only sends out email on failures.

2. Created Genealogy queries to extract specific grading report information as raw data. Created another script to automatically call these queries as URLs and generate a report as a compressed file delivered as a URL link via email.

3. Script to load primary component information into Genealogy to provide complete traceability from one serialized product down to its serialized parts. Previously, this information was stored in multiple databases and spreadsheets.

• Created web-based Electronic Notebook for recording observations at test stations via Tomcat to replace the previous method of text files and spreadsheets used by the team. The new system increased reliability of observations while providing automatic time-stamps per entry, database backup, and report generation to .csv on demand. Text area can be resized by user as needed and entries are encoded in UTF-8 and stored in SQL Server.

• Created web-based Training Quiz for new hires using Tomcat. Quiz administrators can login to evaluate user results and manage quiz content which is controlled via Excel spreadsheets (.xls) using POI, encoded into UTF-8 and stored in SQL Server.

• Created time saving macros in VB for end-users of AspenTech ProcessExplorer by allowing engineers to manipulate multiple like tags at once rather than individually.

Tools:

XFRACAS, SigmaQuest (SigmaSure, Genealogy), Windchill, AspenTech (IP21, ProcessExplorer), Groovy, Java (JDBC, JSP, JavaBeans, Servlets), Tomcat, Glassfish, Adobe Flex, POI, Ant, JUnit, Subversion (SVN), TortoiseSVN (Client), XML, VB, SQL Server 2005
