2011 - 2014LexisNexis Risk Solutions- Built and led a team of highly skilled data scientists and engineers to solve challenging problems for well-known financial, retail, and wireless institutions.
- Collaborated with the product organization to develop next generation credit risk and fraud models and attributes, seeking to derive incremental and unique value from internal data sources combined effectively with third-party data.
- Advanced research and development efforts, including cutting-edge custom modeling algorithm development, creation and adaptation of new data sources, and developing new verticals.
- Created a proof-of-concept to uncover Federal and State tax identity fraud to combat a multimillion-dollar problem where bad actors were using other people's personal identities to get returns sent to them.
- Calculated the Customer Lifetime Value and built attrition models on LifeLock customers.

2006 - 2010First Data- Led custom analysis in the financial services space, building client-specific models and taking the problem from raw data to the final solution, anticipating business requirements and suggesting alternative approaches when necessary.
- Created marketing strategies for a top, frequent flier loyalty program, building consumer clusters and models looking to predict response to a given promotion, designing experimental campaigns, and scoring prospects to optimize new offers.
- Solved a payment reversal risk model problem by applying outside-the-box thinking on a subprime portfolio at a mid-sized US bank. Saved the client a minimum of $2.4 million per year, and provided the breakthrough in our sales process.
- Built a solution for a top 10 US bank in the fraud space that enabled our client to determine which credit card numbers may have been compromised using a skimming device at a gas pump.
- Collaborated with software engineers in developing, prototyping, and integrating state-of-the-art statistical and machine learning algorithms into enterprise analytics software.

The most amazing...
...tool I've built was a series of models that improved the lives of millions of telecommunications customers by creating more strategic, personalized offers.
Employment
Experience
- Predict the Likelihood of Exceeding Mobile Phone Allowances
I built a model for telecommunication marketing to predict the likelihood of an individual cell phone user to exceed their threshold at an early point of the 30-day billing cycle, scorable at any point in the cycle (including very early in the cycle, before day ten), to be able to make a new offer or an add-on offer to the customer. Significant time-aware feature engineering was used, and the models were largely built in XGboost.
- Review flagging
Built a Keras/NLP model to determine whether a product review on nutritional supplements should be flagged for various violations, including profanity and low quality reviews and/or medical advice on a challenging dataset containing multiple changes in business practices.
- Compensation Analysis
Used a Bayesian Network to model the distribution of various components of compensation (specifically salary and bonus) using limited inputs, such as geographic location, years of experience, job function and title, and education. Returned a distribution of which the 5/25/median/75/95 percentiles were of interest to the end user.
- Customer Loyalty and Segmentation
Examined and analyzed the distributions of two major loyalty programs that were to be combined during a merger to ensure data integrity, reduce overlap, and proposing customer segments. Gave feedback to the engineering teams regarding data transformations to render the distributions as equivalent as possible. Built models looking to predict probability of response to a given promotion, designing experimental campaigns, and scoring prospects in order to prioritize work and optimize new offers.
- Fraud Prevention
Built solutions to determine identity fraud during consumer applications. Created features out of interconnected applications using identity elements across a consortium of lenders and service providers including banks, utilities and telcos. Identified and evaluated third party data providers to provide additional lift to models. Used data to create secondary models such as orthogonal credit scores, and to create additional proofs of concepts such as identifying tax fraud and fraud rings.
- Attrition
Built solution identifying required data and models to determine customer subscription churn for a customer in the identity theft prevention space. Combined results with estimation of customer value to route inbound calls to appropriate level customer service representatives.
