BLOGSTAMP.ORG

Created a service which creates and validates certified timestamps for character based content. A certified timestamp guarantees the time at which the content was created.  The site was designed to be a back-end service to blog/cms software.  It uses standard Java encryption packages and is accessed via a REST message over HTTP or HTTPS.

Tools: Java, digital certificates, NetBeans, OSX

EVANSTON

Created a Drupal front-end client which transparently invokes the stamp service when new content is posted.  Donated the client module to the Drupal community; it is active on several websites and has been translated into other languages.

Tools: PHP, MySQL, Drupal, Tomcat, CVS, Linux

CONTRACT:

(07/06 – present)

KRAFT FOODS

Developer: Created a web application for the global supply chain group.  The application allowed clients to split demand forecast across many mixing centers and plants.  The solution functioned similarly to an interactive spreadsheet and allowed clients to redistribute forecast in user-defined measurements and time intervals.  The grids were large and data intensive; the biggest case had 30,000 input field cells and 25,000 historical value cells (on one screen).

Tools: Java, Spring, Spring MVC, Hibernate, JUnit, Manugistics, Oracle, WSAD, ClearCase

GLENVIEW

 (07/05 – 07/06)

TRANSUNION

Developer: Created java application that returns consumer credit data to customers through a batch file interface.  The application was able to handle 25M requests per hour— a fulfillment rate of 7000 requests per second.  The application was backend agnostic and was tested against Sybase IQ, DB2 UDB, and Oracle RDBMSs.

Tools: Java, JDBC, Sybase IQ, DB2 UDB, Eclipse, Oracle

CHICAGO

Performance Tuning: Successfully tuned a batch maintenance application expected to process 65M input records in a 20-hour day (900 records/second); each input record resulted in an average of 35 SQL statements (75% select/fetch) against a 10TB database. Before tuning, the system could process 555 records/second (60% of goal). Achieved SLA by reducing I/O Wait (through faster DASD and data de-normalization) and increasing concurrency (decreased AIX and DB2 CPU utilization).

Tools: Java, SQLJ, JProbe, Wily Introscope, TMON,  DB2, zSeries, AIX, Eclipse, ClearCase

JC WHITNEY & CO.

Enterprise Architect: Led design, implementation, and standardization of all IT related projects across all business channels. Created a message oriented enterprise environment using proven technologies and best of breed applications. Assisted and mentored engineers on principles of design, implementation, performance tuning, and agile methodologies.

CHICAGO

installpro.net: Designed and wrote an application which offers product installation services to customers of retailers (e.g. jcwhitney.com and stylinconcepts.com). The application was accessed via a REST web service and a management GUI. Configured the runtime environment- a tomcat server-farm accessed via load balanced apache web servers. The site and services performed at sub 1-second response times during peak load.

Tools: Java, Spring, Hibernate, UML, STRUTS, XML, Zeus, CVS, WSAD, ANT, Anthill, JUnit, Tomcat, DB2, MySQL, Solaris

jcwhitney.com: Solely responsible for entire software stack and hardware platform.  Decreased response time from 1466 ms to 579 ms and increased availability from 99.46% to 99.99%. This was achieved by tuning the java heap, better usage of caches, and by adding three new application server clones (2 vertical and 1 horizontal).  Designed and implemented the total re-platforming of the previous website using Endeca and WebSphere Commerce Suite. Created and administered scalable, redundant n-tier hardware architecture that currently services 70 concurrent requests per second in sub two-second response times.

Tools: Java, EJB, XML, UML, ANT, Anthill, JUnit, WebSphere, WebSphere Commerce, ATG Dynamo, Endeca, JMS, WebSphere MQ, NetCelera, Apache, DB2, WSAD, CVS, Solaris, Linux

Order Management System: Solely responsible for the technical implementation of data conversion and data synchronization (interfaces) between a new order management system and 23 disparate internal and external systems.  Performance tested and tuned the entire suite of enterprise applications and their integration points. Established the corporate standard for data integration and developed numerous extensions to the integration software package.

Tools: Java, CommercialWare CWDirect, Quovadx Cloverleaf, RPG, WebSphere MQ, iSeries

Product Information Database: Designed an n-tier internet application framework using STRUTS, Informix, and an object to relational mapping layer. Led the implementation of the framework as the company’s Product Information Database that houses over 100,000 skus.

Tools: Java, STRUTS, NetBeans, ATG Relational Views, DB2, Solaris
