Senior Mainframe Application Developer and Analyst

BACKGROUND

Senior mainframe application developer with work experience at the Social Security Administration, the Centers for Medicare and Medicaid Services (CMS), the Federal Parent Locator System (FPLS) at the Department of Health and Human Services, Sallie Mae Student Loans, Verizon Telecommunications, and Maryland Casualty Personal Insurance. Proficient in using IBM Z/OS mainframes, Windows desktop applications, AWS web services, and object-oriented development environments. Familiar with Object Oriented Development environments utilizing JAVA, HFS, FTP, UNIX, HTML, CSS, Sysplex, IMS/DB2 JavaScript, Linux Scripting, XML, SQL, PLSQL, ETL, File Aid, Changeman, Endevor and Oracle. Topaz Devx refers to a suite of mainframe DevOps tools from BMC Software, formerly known as Compuware. Compuware’s Topaz family of mainframe development tools was a mainstay when I worked at Lockheed Martin on all its mainframe projects. It provided modern development and DevOps capabilities for mainframe applications, utilizing Workbench for Eclipse, Total Test for automated testing, and Code Pipeline for continuous integration and continuous delivery (CI/CD). I became familiar with these test tools during my tenure at Lockheed Martin. My assembler language experience was gathered during college studies and production CICS screen modifications. CICS maps are defined using Assembler language macros (like DFHMSD, DFHMDI, DFHMDF) for the screen layout and fields, but these maps are then used by application programs written in COBOL and Assembler, with symbolic maps generated for each COBOL program to link the screen data to program variables

As a Back End Developer assume comprehensive ownership and oversight of client’s critical IBM DB2 database services and related tasks for client’s Administration Tracking System. This is a high-visibility position focused on service management, coordination with vendors, communication, and operational compliance. I was tasked with defining and identifying the problems; analyzes and develops plans and requirements for moderately complex IBM DB2 systems.

Responsibilities included day-to-day, hands-on configuration and patching of the DB2 database. Ensure system uptime, manage change control, coordinate all remediation efforts, and lead recovery testing. This position required a meticulous professional who applies deep technical expertise to ensure accountability, performance, and rock-solid stability across critical systems utilizing RACF as core security software for mainframes (z/OS), managing user access and protecting system resources like data, programs, and files by authenticating users, enforcing authorization rules, and auditing access attempts. Using a system of users, groups, and resources, storing profile information in a database to control who can do what (read, write, execute) on the system, acting as the primary security manager for enterprises.

ITC/ Disability Research File (DRF) (SSA) – dates (8/18 to 2/25)

6401 Security Blvd, Woodlawn, MD 21207

The DRF is a one-of-a-kind data source maintained by the SSA. It monitors individual claimants throughout the Federal Contract disability appeals process and is the only source of data that can provide answers to complex questions about claimant disability logistics. DRF is an IBM Z/OS mainframe BD2 database application that uses queries to access its vast data resources such as CMS within the Department of Health and Human Services (HHS) which runs programs like Medicare, Medicaid, CHIP, and the Health Insurance Marketplace (Healthcare.gov) for over 160 million Americans, overseeing health coverage and quality standards.

I was responsible for writing extensive data queries to access DRF’s resources. I wrote new programs as needed, primarily in COBOL, and maintained existing programs written in various languages, including Micro Focus Cobol, Linux shell scripting, Enterprise Guide, and CICS. I implemented and converted database structures to comply with the new consolidated DB2 formats on an IBM z/OS mainframe platform. This effort required the use of various mainframe tools and utilities, including hands-on experience with IBM mainframe Micro Focus COBOL, DB2, IDMS, CICS, JCL, VSAM, File Aid, Endevor and interactive development tools like XPEDITER, INTERTEST, ISPF, SDSF, SQL, SPUFI, QMF, MQ, ETL, RACF, JavaScript stored procedures, and IMS/DB, as well as Synon/COOL:2E’s Application Development Environment (ADE) to build business applications and interface with Pharmacy Benefit Management Processing Rx claims.

Leidos/BORG Consolidated Enterprise Database (SSA) – dates (8/16 to 9/18)

6401 Security Blvd, Woodlawn, MD 21207

Assigned to the Consolidated Enterprise Databases (CED) project, I was responsible for modernizing outdated software technology. The primary focus was on accessing multiple databases across different environments to gather essential data for daily operations. The upgraded applications would allow for updates to master data throughout the entire lifecycle from a single database.

My responsibilities included developing new programs, maintaining existing systems, and installing converted database structures to match the new consolidated IMS/DB2 format on an IBM mainframe platform. This involved utilizing various tools and utilities such as IMS/DB2 unload and load utilities, Workbench for Eclipse, CICS, VSAM, JCL, COBOL, Endevor, and interactive development tools like XPEDITER, INTERTEST, ISPF, RACF, SDSF, SQL, SPUFI, FTP, GoAnywhere, stored Procedures, IMS/DB, and QMF.

Leidos/Quality Assurance Application - MBR MADAM to DB2 Conversion (SSA) (12/15 to 8/16)

eQA is a web-based intranet application designed to provide the Social Security Administration (SSA) with an integrated platform for conducting quality performance studies and reviews on the accuracy of adjudicative decisions made for SSA beneficiaries. As a mainframe programmer/analyst, I supported the conversion of the IDMS electronic Quality Assurance (eQA) Batch Application MBR MADAM to IMS/DB2. This included supporting both the IDMS and IMS/DB2 applications, maintaining the development/test region infrastructure, and conducting application system testing using COBOL, SQL, IMS/DB2, JCL, TSO, RACF,ISPF and message queue (MQ) support for CICS applications. I employed a structured process for defect reporting, triage, and tracking to manage errors or issues discovered during software QA testing, utilizing Total Test for an automated testing solution. It involves reporting defects, prioritizing them based on severity and impact, and monitoring their progress through resolution. It ensures that critical issues are addressed promptly and that progress is effectively tracked.
