Analytics Engineer @ SolarCity ■ Worked on an Analytics platform/framework for Operations to help quantify and visualize performance within the company. Lots of visualizations to look at data . Using Python, Django, Pandas, Numpy, D3, NVD3, dc.js.■ Worked on a data-warehousing project to help improve the Analytics platform: Created a POC introducing a level-2 data aggregation layer in Mysql/Redis to avoid making expensive calls to the primary Mssql database, using Memcached for level-1. Mysql/Redis layer stored aggregated data for most common or most resource expensive reports (basically SQL views), updated periodically by Celery jobs (using Redis broker). Design based on SEDA architecture.■ Created new frontend interactive widgets using Javascript, D3 (Python to drive the backend) for embedding within reports/table-views and provide a richer analytics experience. From June 2014 to December 2014 (7 months) San Mateo, CASoftware Consultant @ Google ■ Worked on network inventory management tools for Google in Python, Javascript, using Django, Appengine for backend and Closure tools, Highcharts, jQuery for frontend. Also used the Google Cloud platform such as cloud-storage and Blobstore to archive/store cached data.■ Maintained a legacy C++ Map‐Reduce application for extracting and classifying GIS data from large internal GIS data stores (same one used by Google Maps) and writing them to shape files for consumption in ETL project. ■ Worked on automating/hardening a large data-­migration project to migrate Google’s network inventory data from databases/text files/csvs to a larger relational data-­store following the OTN network inventory model.■ Created a reports framework for creating dashboards to help visualize ETL fallouts. Used Google Closure Tools, Highcharts, for frontend and Python, App Engine for backend.■ Achieved Python Readability to help administer Google's python code-base. From January 2011 to June 2014 (3 years 6 months) Mountain ViewSoftware Quality Assurance Intern @ CaridianBCT ■ Developed test cases for the barcode management system in the ASM flagship product. ■ Assisted in designing a test automation framework for black-box testing the ASM software.■ Part of the performance evaluation team for testing/evaluating the ASM server against 32 Atreus simulators.■ Designed and implemented an XML editor to parse large Autotest XML definition files for the STS software.o Expedited test case generation by 24x.
