Experience Profile – Key Projects
Project # Multi-Channel Engagement Behavioral Scoring
Cisco Systems, CA Aug 2014 – Present
Cisco Marketing and Campaigning team requires the cisco customer’s propensity in buying the Cisco
Services/Equipment like Data center, Switches, Routers and etc…. based on the end user activity on various Cisco
subsidiary websites like CDC, Communities, Social and Support websites including the enriched internal data from
various channels. This requires the processing of discrete web logs from multiple instances of various web servers
related to different web sites. As part of this project, we will accumulate, crunch, compute and analyze the data to
come up with distinct topic level scores to indicate user interest in buying appropriate Services/Equipment.
Role Description: Hadoop Developer

Oregon Medicaid (MMIS), HP Mar 2012 – Jun 2014
MMIS is like many healthcare organizations have a legacy system, clinicians and researchers needed access to the
data. The data types include EMR generated data, genomic data, financial data, patient and caregiver data,
incremental physiological monitoring, ventilator data, temperature and humidity data.
Any electronically generated data in a healthcare environment can be ingested and stored in Hadoop. We used for
developing an analytic ecosystem to aide in the delivery of quality care at the lowest possible cost and an
environment to enable clinical researchers to examine healthcare data.
