Project #3

Employer Cognizant Technology SolutionsClient MedStar HealthLocation Baltimore, MDTools Microsoft BI Tools-SSIS /SSRSRole Sr. DeveloperPeriod Aug 2012 – Nov 2013

Project Description

I was involved with the management of Medicaid plans for the client. They had multiple vendors and hospital from where the data used to come in different format and we had to collaborate into a common format. We created a .NET application where in single platform the user can see all the member demographic details and their claims data. There were multiple reports which needed to be migrated from Access database to SSRS. Lot of Ad hoc reports were created using SSRS and deployed in the Report Manager. Based on the report usage I used to provide accessibility to users.

Role and Responsibilities

I was involved into Migrating reports from the old client application such as Access database to SSRS and then deploying into proper folder with appropriate accessibility to the users.

Wrote TSQL/PLSQL queries for complicated reports based on the client requirements. Created Charts and matrix reports in SSRS on top of the above queries.

Created Stored Procedures and Tabular functions in TSQL for the reports. Tabular functions so that we can use multi select parameters for the reports in SP.

Shown users the features of drill down and drill through reports and other advanced features of SSRS so that their old reports can be organized better and exporting into excel will definitely improve the report analysis ability.

Helped in changing the current table architecture so that new functionality can be implemented. Took part in creating data dictionary for various claims table.

Created SSIS packages to populate data for the Member Manager application which was client’s in house .NET application.

Created several other SSIS packages and uploaded excel or notepad output to FTP server or some local folders. Scheduled these packages either for daily, weekly or monthly run. Monitored it and fix if any issue comes.

Wrote queries and packages to maintain the client’s Finance application. Migrated DTS package to SSIS. Created triggers on source tables so that any time new data comes in it the data directly moved to the target

as well. This helped us in avoiding truncation of the target tables every time we load with the new data. Gave required access to new users to the database when ever needed.

Project #4

Employer Cognizant Technology SolutionsClient Anthem BlueCross BlueShieldLocation Richmond, VA/ Bangalore, IndiaTools Microsoft BI Tools-SSIS/SSAS/SSRSRole Onsite coordinator/Offshore Team lead/DeveloperPeriod Jan 2010 – July 2012

Project Description

Client had legacy application and we had to work on it to bring to the updated and current application. They had 68 reports and Stored Procedures which we had to work on and bring up to the current functionality. They also asked to create few new reports out of the cube. We created dimension and fact tables from their current data model. We created 1 cube with 7 dimensions both confirmed and role playing and 3 measure groups. We created OLAP database using these dimension and fact tables. We created charts and matrix based reports and deployed in the Report manager. Part of the assignment was also to bring their application to ICD10 compliance.

Role and Responsibilities

I along with my team members worked with the client and business system analysis to finalize the Requirement document for the project. We used to have daily discussion with them to understand their legacy systems and what all functionality they want to bring up in their current application and reports.

Worked on the stored procedure, some of which were more than 2000 lines to understand it and also to add any new functionality. We used to write new blocks of code or modify the existing blocks.

We wrote dynamic queries because they wanted to have an application in which the database name can be modified by the user. We used to join tables from different database and these database names can be modified during the run time.

We wrote complicated functions which were used in the stored procedure to achieve the desired result. We tested our stored procedure for performance using Performance Monitor and Execution plan. We

tested block of the code which was taking huge time to execute and worked on it to improve its performance. We used temp tables and indexed views.

Worked on formatting the existing SSRS report. Added new parameters in the reports where ever required. Proven ability in defining Query for generating drill down reports in SSRS 2005/2008. Worked with slowly changing dimensions. Used different storage method in SSAS for cube. Used ROLAP storage method for performance of SSAS. Worked with client tech lead to identify the probable candidates for dimensions and facts from the existing

data model and also adding any extra dimensions and facts to achieve the required data warehouse. Used SSIS for implementing the logic to load data in the new dimension and fact tables. Used different type of

Data flow tasks like conditional split, derived column, lookup to load the data in the destination tables. Used Exception handling to notify us and the client for any error caused while loading the data. Responsible for scheduling the packages using Batch files every night and generating Claims reports using

SSRS Drill down Claims Report using Pie Chart or Bar Chart Representation. Developed Stored Procedures, Triggers and Functions. Created different views depending on the business requirement.
