Work Experience

Self Employed

2018 - PRESENT
Independent Machine Learning Consultant
  • Built and deployed multiple personalization ML pipelines to lift offer/coupon conversion rate for customers of major restaurant chain. Application built on Azure Databricks platform with business-configurable pipelines for training, tuning, testing and prediction, using Pandas (Python), Spark (PySpark), sklearn and Spark ML. Deployment to production using Azure Data Factory.
  • Automated, hardened, and deployed multiple ML pipelines on AWS (Elastic Map Reduce with Spark and Lambda) to predict next-best-action, forecast performance and predict/prevent churn for sales representatives of major corporation. Data processing used Python, PySpark and Spark SQL. ML models built using Microsoft ML for Spark.
  • Advised a mid-stage startup on the requirements, features, and architecture needed to support ML pipelines in their high-speed stream processing framework and in-memory data grid. Worked directly with the CEO/CTO and senior technical team.

Co-Founder

2009 - 2017
Skytree Inc.
  • Worked directly with our Fortune 500 customers and collaboratively built predictive machine learning models/pipelines for fraud detection (for American Express), product and media recommender systems (for Samsung), credit risk scoring - consumer and SMB (for American Express and Equifax), Lead Scoring - Premium Consumer Credit Card (for American Express), Balance Transfer Offer Optimization (for Discover), churn prevention (E-Harmony, ShoeDazzle), real estate price prediction (Brookfield RPS), and many others for Fortune 500 clients.
  • Led engineering and data science and ultimately moved to technical product management and ownership for Skytree’s flagship product. Led the research and development of Skytree’s high performance and massively parallel C++ library for tera-scale ML. Implemented (from scratch) mathematically scalable and distributed algorithms for nearest neighbors, random forests, gradient boosted trees, support vector machines, clustering, collaborative filtering, etc. for classification, regression, anomaly detection, and recommender systems. This included many first of the kind innovations in the practical application of ML algorithms to big data.
  • Architected Skytree’s (flagship) Infinity AI platform, including APIs, GUI, and SDKs. The Java-based server coordinated with the underlying multi-tenant Big Data or cloud infrastructure, managing data, users, resources, and scheduling jobs (a mix of Apache Spark for data processing and Skytree’s C++ engine for ML). Platform support included Apache Hadoop (YARN & HDFS) from MapR, Hortonworks, and Cloudera as well as AWS Elastic Map Reduce.
  • Delivered multiple releases of the full stack of Skytree’s AI software as the product manager for all four technical teams (ML, systems, UI, and data science), including defining and prioritizing the roadmap and coordinating release and development efforts across teams.
  • Built world-class engineering (C++/HPC/ML, Java/Systems, and UI) and data science team. Defined requirements, developed and reviewed screening tests, and finalized candidates.
  • Spearheaded the technical sales enablement efforts.
  • Supported POCs, pre and post-sales activities, renewals, through product demos, sales calls, requirements gathering, trade shows, webinars, seminars, and tutorials.
  • Trained solutions architects/sales engineers and had ownership of the technical resources they needed (demos, documentation, guides, questionnaires, etc.).
  • Co-authored five patent applications in the areas of ML user experience, recommender systems, and automatic feature engineering.
  • Recruited candidates for various other positions, from sales directors to senior leadership (VP of sales, marketing, and engineering).
