Sr. SQL/ETL Developer
This was an ongoing project for developing the data warehouse, SMARTDEV, for the joint venture project of United Stage Postal Service and Imagitas Inc., a Pitney Bowes subsidiary company. For the change of address, USPS had introduced the online change of address, the idea suggested by the Imagitas Inc. which further resulted in the development of the portal site, mymove.com. MyMove is the portal site of Imagitas which linked with USPS site. When the user completes the change of address at USPS site he/she is directed to mymove.com where he gets offers of coupons to buy stuff from different companies which could help him in his new move. The main purpose of the project was to develop the data warehouse which on which reports could be developed. These reports will help figure out the revenue generated by the address changed by user and the websites visited by the users in order to subscribe the stuffs using coupons.

  • Actively involved in the data analysis of database architecture of both the USPS site, known as MGO and Imagitas Portal site MyMove (MM).
  • Participated along in removing the then existing defects resulted in the previous release.
  • Altered as well as created transformations using SQL Server Integration Service (SSIS) for data conversion and populating dimensions.
  • Updated the complex queries for the transformations used to populate the fact tables.
  • Optimized the complex queries by creating the indexes on the tables and removing the unnecessary joins and sub queries.
  • Automated the creation of the components of URLs by parsing them in the tables which was previously done manually using flat files source.
  • After getting done with the fixing of the defects, got involved in the second phase which was the data migration from the USPS site.
  • Participated in the design of logical and physical development of the data warehouse.
  • Designed the Snow flake schema using Microsoft Visio for creating STAGE database, ARCHDATA, Central Data Warehouse (CDW) and Data Mart (DM) to accommodate the data from USPS site.
  • Designed and Developed the ETL process to achieve the purpose of the development of the STAGE, ARCHDATA, CDW and DM.
  • Architect the ETL process for bringing the required data from ARCHDATA into dimension and fact tables in DW as per business requirements.
  • Created the basic SSIS Framework Technical documents consisting of Naming conventions for packages, transformations, connection managers, log files etc.
  • Created the base SSIS template package including all necessary components considering best practices like Basic Logging (both SQL server and text file logging), configuration, connection managers, pre execution, post execution etc. This package was used as base for the development by all developers. This package was created taking into account frequently used business requirements making the development process more rapid, modular and extensible.
  • Created Stored Procedures, functions, tables for tracking the package execution process (start time, end time, load information, suspended records, status etc.)
  • Gathered Business requirement for the MGO to support the reporting needs for the analytics team. Worked as a lead developer for the automated workflow process using SSIS packages which implemented Business Rules to validate data, integration with Dashboard to track the status of submission, implementation of business approval process via File system process and successful loading of data to Data warehouse.
  • Created approximately 30 packages including extraction from flat files, excel file, oracle, SharePoint list and load data to SQL server.
  • Implemented all types of control flow and data flow transformations in packages to handle different logics.
  • Created data Warehouse packages to load Slowly changing dimensions (SCD1 and SCD2) using Merge Statement as well as upsert in SSIS (Lookup and Merge Techniques)
  • Created approximately 40 SSIS packages to create Excel reports using VB.Net scripting in Script task to handle custom formatting of excel sheets, including logo etc). All the parameters could be handled dynamically from configuration table.
  • Created various stored procedures using dynamic SQL, advance T- SQL techniques like Common Table Expressions, Pivoting, grouping sets, ranking functions etc.
  • Used event handlers to send custom e-mail notifications to business users as well as technical teams.
  • With the help of the DBA, enabled the Change Data Capture (CDC) in SQL Server Management Studio to create the check point for the data recovery in case of package failure during the incremental or full load.
  • Created the query in Execute SQL task to retrieve the timestamp for the CDC in every package to provide the opportunity to run the package from the point it got failed or to update the table in case of any changes made from the specific time.
  • Created purge process package to delete old files depending upon the retention period. All parameters could be handled dynamically without making any changes in package by using configuration tables.
  • Used SharePoint web service to get data from SharePoint list and load to data warehouse after the data validation.
  • Create XSD and XML files used by SharePoint application from the SQL server database using dynamic SQL.
  • Created build scripts for code promotion to SIT/QA/PROD environments.
  • Created Test cases for deployment to SIT, QA and Production Environments.
  • Used Tortoise SVN on regular basis for version controlling of SSIS packages as well as various T-SQL objects.
  • Created run books for whole the SSIS development for the ease of Production Support team.
  • Accommodated the new transformations in the existing job which was previously loading the data for few tables from USPS site.
  • Updated the Master Job for the change made for MGO data and ran it in development environment.
  • After validating the data integrity and data conversion moved the transformations and jobs to the testing environment and made the final integrity test.
  • Following the decision from company\'s executive, participated with Architect and Project Manager to move ETL process from SSIS to Pentaho Data Integration.
  • Participated in installation and configuration of the PDI version 4.2.0 server and created the repositories in Development, Test and Production.
  • Created the connections in the Kettle properties for extracting the data from databases and excel sheet and flat file from Linux server.
  • Designed and developed the transformations in PDI based on the existed ones from SSIS.
  • Created the table for logging the basic and detailed package activities during the execution period.
  • Actively involved in architecting the SMART job for daily load into STAGE, ARCHDATA, Date Warehouse and Data Mart.
  • Moved the SMART job in Test environment along with all the transformations of STAGE, ARCHDATA and PROD.
  • After the successful testing for quite a few day in Test environment, moved SMART job to PROD stopping the SSIS jobs.
  • Log table was monitored very closely for about a week and data validation was done on regular basis.
  • After the successful deployment of the SMART jobs the regular user stories were followed to create reports using SQL Server Report Service.
  • Provided 2 months of Production Support which includes maintaining and documenting communication with business users on daily basis to resolve data related issues.
