Developed Grails application to replace PeopleSoft app for large insurance firm in St. LouisImplemented auditing, change reports and life cycle for life insurance policies using Groovy Metaprogramming and GORM EventsWrote criteria builder and integration tests for searching large domain classes with over 100 fieldsRefactored the above criteria builder using dynamic methods created according to the search criteria. Drastically reduced the size of the code and improved code coverageProvided test coverage for "legacy" Grails app using Gmock, basic Groovy metaprogramming and Grails' built-in test helpersInterfaced with Oracle stored procedures, views and linked databases using Hibernate, GORM and bare jdbc calls when performance was needed. Used Quartz plugin to schedule large data imports and generate hourly report dataImplemented simple try/wait/lock process using Groovy Threading and concurrency to lock reports while report data was being imported/refreshedUsed Gorm Mapping inheritance as well as Domain Class inheritance to design database with large amounts of similar domain classes and lookup tablesUsed Hudson CI to build and deploy all environments. Only builds with 100% passing tests were deployed. Used Codenarc and Cobertura reports to make incremental improvements to code having weak coverage or bad design patternsAgile development process (pair programming, test-driven development, informative work environment and two week iteration cycle)Gave presentations on the "Geb" and "Spock" testing at Gateway Groovy users group

TekSystems contractor working for A.G. Edwards, St. LouisCreated and maintained Perl CGI scripts to process large amounts of stock transactions. These scripts would generate CGI forms allowing users to query and confirm "blocks" of trades stored in an Informix database. These blocks would then be sent to Bull mainframes via FTP. Confirmation would be based on the generation of zero-length files on the target systemWrote Perl batch scripts to confirm success of trades. Scripts would input COBOL formatted files from Bull / Himalaya mainframes, and reconcile the trade prices and shares with an Informix database where the trades were originally generatedDeveloped a Visual Basic program that sends stock pricing and account position files to an outside data warehouse. Program uses an open source encryption program, "GNU Privacy Guard" to encrypt outgoing data and decrypt confirmation files generated by the vendorWrote Visual Basic applications to interface with third-party investment software running on InformixSet up remote testing using Citrix MetaFrame. Users could log into vendor's machines in California and test upcoming software. Test data for this project was encrypted and sent using Pretty Good Privacy 6.5.8.Made multi-user software more failsafe and responsive by using Informix locking methods and wait modesUsed Visual Basic to send trade orders to wire printers hosted by Himalaya systems. Proprietary protocols were used to initiate, print, and confirm printing of trade requests
