WORK HISTORY

EC3 Federal Services

Sr Java Developer, 08.2023– 11.2024

Working as a developer at the Internal Revenue Service IRS within the US Department of the Treasury. This is with the ITPE CADE2 contract. Much of the IRS software was written in the 1960’s IBM 370 Assembly Language. The Contract deals with moving this code base of over 500,000 lines of Assembler code to Java. My main task was to triage defects uncovered during testing, debug the Java code and fix the issue. This involved work with Core Java with JUnit5 using Mokito, some use of Spring. The chief challenge in this project was working with old legacy code and also with an extensive and complex domain based upon statute.

Deloitte Consulting

Senior Solutions Specialist, 07.2022– 06.2023

Consultant in Deloitte’s GPS Government and Public Service Offering. The main project I worked on was with the Internal Revenue Service IRS within the US Department of the Treasury. This was with the ITPE CADE2 contract. Much of the IRS software was written in the 1960’s IBM 370 Assembly Language. The Contract deals with moving this code base of over 500,000 lines of Assembler code to Java. My main task was to triage defects uncovered during testing, debug the Java code, and to compare the Assembler language output with the Java output and determine where the issue was.

PennyMac through Infosys

Java Developer, 08.2021– 05.2022

Java Developer, 08.2018 – 09.2021

Wrote an important Java based API to obtain customer related data consumed by an online API as an MVP project. This was delivered on-time and has been in production for nearly two years. This API was written against a DB2 database in a manner that creates as few objects as possible to be garbage collected . This API is now delivering on about two hundred times more volume that previously anticipated. Later this API was migrated to Oracle as a version 2 API so that both Oracle and DB2 could be supported from the same code base. The API uses Spring and Spring Boot for easier configuration. Supported two on-line web applications that used JavaScript, JSP's, Java JDBC, and Spring. This included enhancements for new business rules as well as continued work to eliminate security vulnerabilities.

PROFESSIONAL RECOMMENDATIONS

Dave Fitch, PennyMac (Private National Mortgage Acceptance Co.)

I supervised David, as he provided operations system support to a vital system in our daily loan processing. David was brought in to fill in for another staff member who had to step away. David came up to speed quickly. I soon came to appreciate David's work ethic and thoughtful approach to his responsibilities. When critical data issues occurred, he was willing to step up and invest whatever input was necessary to address the issues. In addition, David was reliable in attending meetings and quick to respond to emergencies that occurred. David also was proactive in following up on issues that occurred, to try and prevent them from reoccurring. Finally, David was enjoyable to work with.. both easy going and building good rapport with those in our organization, while still taking the work responsibilities seriously. I would recommend David for future openings and would welcome working with him again in the future.

Gretchen Jones, USDA, Accredo Health, Continental Healthcare

I've worked with David at three companies over the course of twenty years. David has always provided value to the teams he worked with through thoughtful analysis and conscientious application of technique. He keeps current on technology issues and does overall excellent work. I have been on the receiving end of his design, coding, and documentation and have always thought his end product was delivered with clarity and precision. He mentors coworkers without bias is patient and helpful with junior developers. He would excel on a collaborative team but can also work independently. David would be an asset to any organization.

Terry Mullett, USDA, VML

I have worked with David on two engagements and have known him for about 10 years. He has always impressed me with his dedication, the diversity of his technical skills and his ease in interacting with people. David brings wonderfully formulated insights to the problem at hand, and expresses those insights well.

Laurie Craig, Accredo Health

I had the honor of working with David at Accredo HealthSystems. David is an energetic, knowledgeable self-starter and takes his responsibilities seriously. He recognizes that excellence is a journey and not a destination which speaks volumes in regards to his work ethic. He was always willing to accept responsibility for his work and work with the other teams to resolve any conflicts and bring the project to a successful completion. David was instrumental in building the teams and designing the architecture necessary to take Accredo to the next level and make them a major competitor in the industry. I would enjoy the opportunity to work with David again!

Maribeth Greene, Accredo Health

David and I worked together on several projects at Accredo Health. I consider David a master at his craft. He is diligent, detail-oriented, and customer-focused. He was able to take the complicated needs of the business and provide a successful end product. I still consider the Medco / Accredo alliance one of our greatest accomplishments and I believe it would not have been possible without David. I would want David a part any team based on his dedication to meet aggressive deadlines and exceed expectations.

Lorna Thompson, Accredo Health

During my 20+-year career as a Technical Writer, Technical Editor, and Business Analyst, David has been one of the most exceptional programmers with whom it has been my pleasure to work.

In addition to working literally shoulder-to-shoulder with Dave for over seven years at Continental Healthcare Systems, where he was THE SME for the company's Matkon 2000 product, we later worked together as contractors on a conversion project for Gentiva Health Services/Accredo Health Group. Our team for this project included Dave as Development Lead, and me as Senior Business Analyst.

Accredo is a specialty pharmacy division of Gentiva focused on the time-critical, overnight delivery of diabetic drugs and insulin infusion supplies. Specifically, Dave and I worked on a clinical reports conversion project migrating pharmaceutical data from an AS400 system to an Oracle environment. Accredo was converting from a legacy reporting system to a new system that they had inherited through the acquisition of Gentiva Health Services. The newly acquired system required extensive customization because Accredo is a much larger operation than the older system was designed to support.

Dave lead our team's programmers in an agile development model through multiple iterations to obtain the required data. Dave's flexibility and talent were key to the success of the project.

Stephanie Simpson, Accredo Healthcare

David Owens served as a lead technical analyst and consultant during his years at Accredo. The work that David produced at Accredo directly resulted in the generation of significant revenue for the company. David was highly effective in his role because he was able to interact with both business audiences to define requirements and developers to communicate and document detailed technical requirements and specifications in a timely manner. I knew that I could count on David to go the extra mile to meet target dates for delivery and exceed customer expectations.
