PROFESSIONAL EXPERIENCE

SRA International July 2012, 2012-Present

Senior Informatica ETL Developer in FDA MARCS development team

This project is funded by FDA. I am participating in designing and developing ETL application to migrate and integrate FDA data from FDA legacy system(FACTS) into current online system(MARCS) using Informatica 9.1.I am also participating in development job of distributed database Synchronization using Sybase MobiLink 12

Quality Software Inc. (QSSI) April 2010 –July,2012

Senior INFORMATICA ETL Developer in CMS IDR Development Team

Developing DST/1a (Delivery System Tracking) project

This project is funded by CMS. I am designing and developing the ETL architecture and applications. CMS wants to merge 2007~ 2010 all data in CMS Chronic Condition Data Warehouse(CCW) into IDR data warehouse. Source data files are SAS generated data files, which include Beneficiary Summary and Condition data files, Part D service level data files, Part A and Part B service level analytical data files, Readmission and quality data files. Since the data files are very big (nearly 1000 G), we use taradata best practice scenario. That is we use teradata fast load utility to load source data into IDR stage tables and then use INFORMATICA full push down to extract, transformation(normalize) and load data from stage tables into target tables. All source data file loading are automatically processed and loaded (Source data files are put into a folder, and then a master script is run to start loading source data automatically).

Developed HITECH NLR (National Level repository) project

This project is funded by CMS. As one of Key Persons, I participated in whole life cycles of this project. I participated in NLR project’s design and development which include Hospital Based Determination, Allowable Charge calculation and HPSA determination. The source data of the project come from IDR CLMNCH part B tables and VSAM flat files (HCPCS Codes and HPSA zip codes).I also developed Teradata fast export scripts to export Hospital based, Allowable Charge and HPSA V2 views into three flat files for CMS end users. The development environments include Solaris 10, Teradata version 12/13, Informatica 8.6/9.0

Developed NPI Crosswalk Project

This project is funded by CMS. This was an existing project. Since source data was changed from snap shot source data to delta source data and the data layout was also changed. I re-designed and re-developed source data loading ETL application to load source data into stage tables and also modified existing ETL application to load historical legacy NPI data and their legacy/ NPI mapping data into IDR tables.

Z-Tech Corporation, a ICF International Company Dec. 04 – April, 2010

Senior INFORMATICA ETL Engineer, Cognos8 BI developer

Developed Chronic Care Initiative-Information Management System (CCI-IMS) 04 ~Present

This project is funded by Centers for Medicare & Medicaid Services (CMS).CCI-IMS is a large, regional pilot program that will support up to 30 regional groups that are supported by Medicare and Medicaid. This project includes three parts: Data warehouse, Cognos7.x/8.x reporting and Java/J2EE Web Management System.

• Participated in Design of CCI-IMS Data Warehouse (ODS) and Data Mart.

CCI-IMS Data Warehouse (ODS) reserve beneficiary, claim history data( Intervention and

Control Group), Beneficiary daily eligibility data, beneficiary participation data, PDE data and netted

claim data. These source data files are VSAM sequence flat files and come from CMS mainframe. Some

data files have variable length record (OCCUR DEPENDANT ON CLAUSE in Cobol Copybook).

• Designed and developed CCI-IMS ETL Data Automatic loading Framework using Informatica PowerCenter7.x/8.1 and PowerExchange8.1.1 and UNIX KORN Shell

- Developed Unix KORN shell scripts to automatic loading data which includes starting workflow and dynamically passing session parameters to parameter files

• Designed and developed Audit ETL/Informatica PowerCenter processes including mapping, session and workflow. The IMS audit source data(daily eligibility, participation, etc.) are pipe line delimiter, fixed length flat file and report formatted text file.

• Designed and developed Data De-identification Framework using Informatica Powercenter8.1.1

This application can de-identify CMS beneficiary data, netted claim data(original and refresh), daily eligibility data and baseline daily eligibility data, randomization bucket data. All the data files are VSAM flat files, which come from CMS mainframe. The de-identification business logics are implemented by Informatica PowerCenter8.1.1 mappings/sessions/workflows and automation of data process is implemented by KORN shell scripts .For the variable length netted claim data files, we use Java customer transformation to process “OCCUR DEPENDANT ON CLAUSE” data structure. In order to improve performance, I use multiple partition to process Original baseline Carr data(the size of one file>8G).

- Designed algorithms to de-identify beneficiary, netted claim and other data.

- Developed mappings, session and workflow to de-identify beneficiary data which include three

HICANS, BOD and etc.
