PROFESSIONAL EXPERIENCE:

Sr. Developer

Confidential

Responsibilities:

• Created 1100 JUnit tests that run as part of every build
• Significantly reduced technical debt by correcting over 12,000 code quality issues
• Designed and implemented a JPA-based application that migrated data from an older version of the application
• Rewrote and enhanced the server side of an existing product that predicts, sets, and stores a user's ps for a multi-lingual web site, e.g. currency, language, and geolocation.
• Added over 1200 JUnit tests to the existing test suite
• Reduced technical debt by over 60% while the size of the codebase more than doubled
• Created an automated data-driven integration test framework that invokes the Selenium HtmlUnitDriver during the integration-test phase of a Maven build . The driver in turn interacts with the build deliverable that's been deployed to a temporary Tomcat instance created by the Cargo Maven Plugin.
• Added the ability to reload a client configuration at runtime without restarting the application, allowing application administrators to rapidly evaluate changes to a client site in real time
• The reload capability was leveraged by another application, allowing rapid prototyping and preview of proposed client configurations
• Designed and implemented a sophisticated analytics gathering enhancement that allows the business to measure the performance of the rules engine all the way down to the evaluation of a single constraint within a rule. This allows the company to provide more precise feedback to their clients, which can be used to reduce the abandon rate on their web sites.Rewrote a RESTful web service that provides geolocation data based on IP addresses.
• Converted it to use Spring MVC
• Changed the process that updates the 3rd party GeoIp data file from one based on an external script, to an application based feature that automatically downloads the file, validate its integrity, and installs it the first time the application it is started, then updates it in a similar manner at configurable intervals.Assisted with the maintenance and upgrade of the team's continuous integration infrastructure. Introduced the use of the SonarQube code quality platform to the organization. Created the first automated, data-driven, integration test suite in the history of the company. Produces the highest quality code in the organization, with technical debt ratios at around four percent and a low defect rate.

Sr. Developer

Confidential

Responsibilities:

• Modeled a star-snowflake database schema that holds pricing guidance data provided by a third-party vendor
• Created a basic rules engine in Java that queries the guidance data and wrapped it in a standalone service
• Increased revenue by enhancing the online ordering application allowing sales representatives to easily leverage complex pricing guidance information
• Designed and implemented a service that persists pricing information (rules) specific to a customer or group. Acts as an adapter between internal pricing systems and an external vendor's revenue management system. Supports multiple clients and multiple persistence strategies.
• Assisted in the implementation of a REST interface that wraps the core service
• Delivered Java applications of the highest quality based on objective industry standard metrics
• Demonstrated the value of static code analysis by installing the organization's first Sonar server
• Enhanced the overall quality of the code base by introducing the use of mock objects to the client
• Created a set of load tests using JMeter to benchmark the performance of a revenue management application
