PROFESSIONAL EXPERIENCE

October 2016 – present Consulting LLC Owner and CEO Los Angeles, CA

• Provide consulting in Advanced Analytics employing my experience & expertise necessary for helping a company to be successful. Applying contemporary statistical & machine learning methods, which ensure that executive decisions are based on information extracted from data. It includes data visualization, data mining, building predictive statistical models, etc.

• Skills: Analytics Subject Matter Expert, Able to look at the business holistically, Provide efficient scalable solutions for business problems, Well versed at conveying complex analytical results to a non-analytical audience, Expert knowledge of Construction of Models, Data Mining, Cluster & Segmentation Analysis, Fraud/Pattern Recognition, Discriminant Analysis, Factor Analysis, Statistical Estimation Theory & Hypothesis Testing, Forecasting, Regression Analysis, Marketing Analysis, Survey Design & Analysis, Workforce Analytics, Statistical Inference from Samples of a Random Size, and Actuarial Mathematics & Risk Theory.

• Extensively use statistical/machine-learning tools (SAS Enterprise Guide, SAS Enterprise Miner, R, SPSS, Minitab, Statistica, KXEN, etc.) in extracting information from large datasets related to disparate sources. Am proficient in SQL, Access, Excel, Word, PowerPoint, and visualization tools such as Tableau. July 2013 – Oct 2016 Cisco Systems San Jose, CA

SME - Analyst

• Was developing predictive statistical models and conducting various types of data mining in a commercial environment to the end of solving diverse important business problems originating within Cisco Systems. Some of the successfully delivered projects are as follows:

a) Analyzed Return Materials Authorization (RMA) volatility in company’s products by using tolerance intervals and z-scores and have built a predictive statistical segmentation model that reveals RMA trend information by identifying and profiling segments with different RMA levels & ranks the involved predictors with respect to their importance.

b) With the objective to measure the impact of best practice (BP) rule violations on 2

syslog errors and, subsequently, to prioritize BP rule violations, conducted the analysis of relation between syslog errors and BP rule violations, identifying segments related to various rates of BP rule violations and have created the criterion for identifying a “bad”/”good” BP rule on a considered data set. c) Built robust and accurate predictive statistical models that allow evaluating banks’ network risk by utilizing software and hardware complexity & consistency metrics as predictors. The associated profile of the target variable describes each level of risk in terms of identified ranges of predictors.

d) Built a robust predictive logistic regression model for network disruption based on available information. The associated risk profile depicts pattern recognition in terms of identified ranges of predictors. This model is a building block for a warning system that will recognize symptoms of a serious error/disruption, which will occur in the next 10 seconds, and will allow taking an appropriate preventive action.

e) Proposed a design of Company’s Best Practices service request (SR) quality standards and outlined a Pattern Recognition method for identifying SRs that are open in a considered month & will be “incapable” of meeting these quality standards in the next month. The method is consistent with Statistical Quality Control Best Practices. The result is an Early Warning System, derived by building a predictive logistic regression model and by using the mentioned method for profiling the small group of recognized “incapable” SRs. f) Designed and implemented a holistic approach to Connected Analytics for Collaboration (CAC), which brings the CAC product quality to competitive standards that are required to make it useful for customers and distinguish it (with its unique advanced analytical features) from other existing Collaboration products.
