Work History



Senior Java Application Specialist

First Data, Greenwood Village, CO

Responsible for application design and development for the Electronic Federal Tax Payment System (EFTPS) applications on a distributed platform. This is a high volume, high availability payment processing system executing in a multi-tier environment. My group is responsible for the public input methods via Web UI, Web Services, and a Windows Rich Client. This includes the IRS’s DirectPay website, the EFTPS Online Website and the downloadable Batch Provider Client Swing application. Additionally, worked on numerous in-house custom applications.

Worked independently with IT functional units and business units. Recommend strategies for broad system improvements.

Responsible for analyzing, prototyping, coding, testing, documenting, application software.

Part of my responsibilities involves supporting existing business systems applications. Work on billable revenue generating projects for EFTPS; collaborate with senior developers, business analysts, project managers across teams to identify business needs and build appropriate technical solutions.

Ensure adherence to established standards and consults with senior architects on technology solutions.

Wrote an extensive battery of integration tests using Selenium. These tests assure the behavior of the DirectPay application met or exceeded the agreed-to written specifications. The Selenium tests started catching problems almost from their inception thus paying for themselves time and again. During our last release the IRS was extremely pleased with the stability and behavior of the application.

The EFTPS application suite is built on a foundation of Java, Spring, Swing, Spring Web Flow, Tomcat, Selenium and several other J2EE technologies. Stability and usability are paramount for this site as the IRS accepts tax payments from this website. This results in significant revenue for the United States government.
