An accomplished Computer Professional with an extensive background in TPF,

the Operating System used by many Airline Reservation Systems and other

extremely large Transaction Processing Systems (VISA, American Express,

etc). This experience encompasses Operations, Development, Testing and

implementation of major components, and coordinating all this in tandem

with QA to insure the successful implementation of any project.

Also worked closely with users to ensure documentation of requirements was

accurate. This ensures a timely delivery and also the ability to break up

the entire document into smaller tasks which could be given to individual

programmers.

KEY SKILLS:

Computer Languages: IBM S/390 Assembler, C, ISO C, Sabretalk, REXX, and

BASIC.

Extensive experience in Edifact and XML messaging.

Involved in Design, Development, Testing and Implementation, of key

application software from inception to ultimate approval by QA.

Excellent verbal and written Communications skills.

Customer Support

ADDITIONAL SKILLS:

Prior use of COBOL Java and Oracle

Trained in Java and the use of Eclipse for Java projects.

Experienced in supervisory roles.

PROFESSIONAL EXPERIENCE:

Jan09-Mar11 Amtrak, Washington DC

Computer Programmer on Amtrak's TPF computer reservations system. Experienced

in XML, EDI/Edifact, Cargo IMP and computer tracing.

Nov02-Jun08 Citigroup, New York City, New York

Computer Programmer. Responsibilities include modifications of and additions

to Citibank’s TPF System in Assembler, Sabretalk and ISO C programming

languages. Areas of expertise include Debit Card Authorization, Mortgage,

Encryption and XML processing. This involved intense cooperation with QA to

insure a positive outcome. I often had to work in tandem with QA to insure

the code I implemented was operating as designed. If QA found a problem,

the code went nowhere until the problem could first be duplicated and then

proven to be fixed with the updated code.

Feb01-Sep01 Open Skies, Salt Lake City, Utah

I was a Reservations Systems Analyst. I worked as a contractor with Open

Skies Personnel to affect the creation of a multi-hosted airline reservation

System that would ultimately serve, among others, Jet Blue, AirTran and

Virgin Air. Contract halted due to Sept 11, 2001 catastrophe.

Oct98-Dec00 Datalex, Atlanta, Georgia

Programmed in C primarily for conversion of web-based online reservations

“BookIt!” from C to Java. “Bookit” relied on information received from

Amadeus in Europe, Worldspan in Atlanta, and Covia in Denver. Data was

primarily gotten through “screen-scraping”. Worked closely with users

and QA to insure the software was working as expected. Programming support

was eventually transferred to Dublin, Ireland.

Jan98-Mar98 Indian Airways, New Delhi, India

Contracted to make modifications to Indian Airlines reservation system.

I primarily reported to British Airways personnel and was subcontracted

out to Indian Airlines.

Apr95-Dec97, Mar98-Sep98

Navitaire, Minneapolis, Minnesota

A relatively new player in the airline reservations industry, Navitaire

required that I worked on a contract basis in various airline and

airline-related shops around the country using heavy assembler programming

including via itself; US Air in Winston-Salem, NC; the TPF reservations

Center in Atlanta, GA which serviced Northwest Airlines, Delta Airlines,

and TWA; Jet Blue’s reservation center in Salt Lake City, UT; and

Continental’s reservation center in Los Angeles, California.

Dec91-Mar95 Delta Air Lines/Worldspan, Atlanta, Georgia

BAL/TPF Programmer for Delta Airlines and later Delta’s TPF software partner,

Worldspan. Major accomplishment was with a package called “Seamless

Availability”. I programmed the application that responded to Covia’s (United

Airlines’) requests for instantaneous availability on Delta’s reservation

system.

Oct82–Dec91 Pan American World Airways, Rockleigh, New Jersey

Programmed primarily in IBM BAL (Basic Assembler Language) in a TPF–based

environment. Responsibilities included, but were not limited to, the Pan

Am online cargo reservation system (Pantrac). In this role I supervised

between 6 and 8 programmers for 7 years until the company went bankrupt.

Education: Manhattan College, Riverdale, New York

Bachelor of Science degree

Dual Major: Computer Information Systems and Marketing.
