Trouble shoot data analytics and developed algorithm to digitalize data by using technology through converting PDF files to Text Files then parsing and extracting key performance indicators from those text files for energy, renewed energy and waste management payment bills to reduce manual data entry for related business entities. Such technology could be applied to mortgages, hospitals and any firms who are using manual labors for data entry or interested to convert paper based data and use that data in all aspects of their businesses to do predictive analytics so as to drive business growth.

Marketing Researcher & Statistician Aug, 2008 – Dec, 2012

ADP/Cobalt, Seattle, WA

Served as lead statistician for the Business Intelligence group, executing analytics and marketing projects to inform critical business decisions with impacts to revenue, marketing strategy, and business operations

Key accomplishment: developed the Dealership Advertising Package (DAP) Cancellation Model:

Methodology: used Survival Model/Accelerated Failure Time (AFT) Model, and Logistic Regression Model

Created a predictive model to estimate the probability of cancellation of the DAP product subscription, a major source of revenue, using the DAP subscriptions web analytics data, site performance data, and behavioral data from employees assigned to the accounts

Created a secondary behavioral model to predict the probability of retaining the product, given employee attributes and aptitudes

Result: my models successfully isolated key risk factors for cancellation and directly produced changes in how ADP/Cobalt sold and managed the DAP program, resulting in significant cost savings for my firm.

Other projects and highlights:

Designed and administered a “Pre/Post” Survey to measure a respondent’s behavioral intent before and after the respondent’s visit to a specific website

Assessed consumer/user experience by testing hundreds of web pages, site sections, and site features to determine which individual page influenced behavioral intent (after deriving several thousand variables from those features).

Developed a custom segmentation algorithm based on brand and model preferences, buyer readiness level, shopper type (i.e. vehicle buyer vs. parts and services buyer), etc.

Developed a custom search phrase parsing algorithm; by using both exact-match and fuzzy-match algorithms, my work product grouped the search phrase so that paid search produced a better conversion rate and a lower bounce rate
