BACKGROUND
With more than 25 years in the Information Technology industry, I have a wide range of
experience in all phases of the software development life cycle and consistently produce quality
solutions that adhere to customer requirements while meeting project budget and time constraints.
I have strong data architecture skills and experience with software development process design
and implementation. Working with the business to develop ways to increase productivity,
improve sales effectiveness or reduce costs is especially satisfying.
Enterprise data architecture and data delivery to provide data and information to end users for
identifying new business value is what I would like to be involved in. Data warehouse modeling,
data integration / ETL and data analysis and reporting requirements development are aspects of
BI projects where I can provide value to your team.
EXPERIENCE
Tier 2 State of Colorado (12/2014 – Present)
 Carrier Change Reporting Improvement
 Spent six months modifying a system being used by the Colorado Health Insurance
Exchange to communicate changes on existing insurance enrollments to the
insurance carriers.
 Needed to add and maintain objects developed using Oracle PL/SQL and Microsoft
SSIS.
 Helped to documentthe system along with improving data quality and dependability
of the process.
 Informatica Developer
 Took over maintenance and operation ofthe Informatica ETL mappings and
workflows. Came up to speed on a tool I had no experience with in the past.
 Maintained and enhanced a 250 table type 2 data warehouse load process.
 Operated and improved the ETLs and manual processes used to extract data for
reporting enrollments to the federal government’s IRS and Medicare agencies.
 Developed new ETLs for extracting small business enrollmentdata to do federal
reporting.
Data Modeler Tufts Health Plan (09/2014 – 12/2014)
 Modified physical data models and produced DDL for project teams in support of the
client operational data store.
 Developed data model peer review checklist and implemented a process to automate
some of the model checks. Developed a report (Crytal Reports) to export model data from Erwin
into Excel. Created Excel macros to import data from analysis spreadsheets used in the SDLC at
Tufts Health Plan for communicating data mapping and created lookups, cell compare functions
and pivot table reports in the model checker spreadsheet to identify issues with the model.
Tufts is transitioning from Erwin to Embarcadero’s ER/Studio so I created ER/Studio macros,
which use a visual basic language

data from the federal data services hub,the state department of revenue and the exchange application portal. Provided
database information and reviewed designs from application architects and designers.
 Created schema architecture and processes fordatabase deployment, created data security approach for securing Internal
Revenue Service data using Oracle database vault and designed and implemented data change auditing using Oracle change
data capture.
 Assumed data modeling for functions in change request processes and continued to provide application to database mapping
for new development.
 Developed PL/SQL packages to support data movement between primary integration points of the individual application
portal and the state worker portal for eligibility data.
 Designed and implemented data audit systemusing Oracle’s change data capture system.
 Assisted many team members with integration and requirement implementation where database persistence oraccess was
required.
 Managed team reviewing reporting requirements, developing a data warehouse model and Cognos reporting including
