PROFESSIONAL EXPERIENCE:

Confidential

Project Lead and Solution Consultant

Responsibilities:

  • Confidential tool enables planners to setup products for supply checks, auto-extend quotes if prevailing quotes cannot be supported and also schedule quote changes to take effect at a future date/time.
  • Enterprise datawarehouse(EDW) in Teradata interfaces with SAP GUI to determine quote changes.
  • There was a lag of 1.5 hours between EDW Open Orders/ Inventory snap and AQE sending the recommendations resulting in multiple excess orders during demand spikes.
  • Identified alternate sources where Open Orders and Inventory reaches EDW with minimum latency of 5 mins.
  • Also, compared different technology platforms like Vertica for feasible solutions.
  • Engaged Infrastructure, Operations teams and management to in corporate changes in ETL framework to capture real-time snapshots.
  • Parallelized execution of independent modules and maintained data consistency in presentation layer by designing new metadata logic.
  • Analyzed round-trip times for 2 months and quantified the results using Tableau and SQL query results.
  • This improved data freshness and quote accuracy in auto-generated Business Objects reports; eliminated manual work with quote monitoring and adjustment ; improved customer conversion reduced excess costs by enabling quote strategy to be aligned with build strategy.

Technical Solution Consultant

Responsibilities:

  • Automated Regression testing tool is based on the concept of Continuous Integration where every time a developer commits a code it triggers the execution of a set of pre-built test cases to validate the changes and merge small changes during Integration testing.
  • Python, Selenium and Protractor technology was used to automate Quality Assurance testing.
  • Organized meetings with the developers of the tool and enhanced features like automated test data setup that caters to all functionalities of an application.
  • Quantified effort required and analyzed objects in scope and identified test data requirements extending to certain rare scenarios.
  • Baselined test data bed for future builds and communicated the purpose of the tool to all developers.
  • One-time setup of the process eliminated merge conflicts and duplicated efforts.
