The most amazing...

...thing I've built is a deep-learning algorithm to detect market moving events in the stock market. We were able to help hedge funds reduce portfolio volatility.


  • Lead Data Scientist

    2019 - PRESENT
    • Responsible for the construction and optimization of a geospatial system that maps physical ad impressions based on vehicle GPS data and mobile GPS data. The Mobilads geospatial system was successfully built to operate worldwide and built to scale to thousands of vehicles and billions of GPS points.
    • Built automated reporting systems for the clients of Mobilads to demonstrate the technology.
    • Continuously built up the company's IP portfolio through the integration of census, geotracking, and social data to enrich what Mobilad's knows about the people that see their vehicles. This ensures consistent industry-leading return on ad-spend.
    Technologies: Python
  • CEO (Previously Chief Data Scientist)

    2017 - 2019
    • Led a team of 15 data scientists, linguists, software engineers, product managers, and sales professionals.
    • Focused primarily on deep learning for text classification with Keras and Tensorflow, and its integration within a rule-based NLP system.
    • Developed an out-of-memory document clustering system to allow the clustering of billions of news articles.
    • Built a natural language processing (NLP) system that rivaled the best NLP companies in finance, and led to data trials with some of the largest fund managers.
    • Led and oversaw the Newsful application ( that was shortlisted for the 2018 SIIA CODiE Award. The business operations were acquired by Commetric (
    Technologies: Python, Keras, TensorFlow, R
  • Contract Data Scientist

    2017 - 2018
    • Designed an end-to-end machine learning application using Google Cloud to serve as an API for the front end team.
    • Matched candidates with businesses by utilizing staff demographic data, historical job data, and interview transcripts.
    Technologies: Python, Google Cloud
  • Data Scientist

    2016 - 2018
    • Built analytical tools and ETL pipelines in Spark on AWS.
    • Built predictive tools for targeting audiences for specific ad campaigns.
    • Developed interactive data applications for product owners using Python and R (Shiny) to automate time-consuming analysis tasks (customer journeys, return on ad spend).
    • Developed a system to optimize how ads are placed within the search and recommendation engine to reduce lost revenue due to poor ad placement by up to $0.5 million USD per month.
    • Designed a system for determining the causal impact of multiple concurrent ad campaigns (off-site, on-site, banner Ads, and full-page ads) using regression and Bayesian time-series models.
    Technologies: Python, Spark, R


  • Newsful (Development)

    Sigmai’s proprietary NLP technology enabled our customers to be the first to act on breaking news and allowed us to build an unbelievable archive of corporate history.

    Newsful was a demonstration of that technology, and was shortlisted for a CODiE Award in the Best Business Intelligence Reporting & Analytics category.

  • Sigmai: Skynet Natural Language Processing System (Development)

    Lead author of a proprietary end-to-end deep-learning based NLP system for classifying text.

    Achieved state-of-the-art results for entity-based classification (classifying text as it relates to a specific entity in the text).

  • NHL Systematic Betting (Development)

    The goal for this project from the outset was to predict the outcome of hockey games and attempt to find systematic errors in betting odds by traditional providers such as Bet365 and Pinnacle.

    The system began to approach parity in capability with the best provider in January 2019, and surpass it in February.

    Put into production in March 2019 and successfully traded throughout March for a 200% profit. The system is currently being prepared for commercialization for the 2020 season.

  • For a successful natural language processing project, collecting and preparing data, building resilient pipelines, and getting "model ready" can easily take months of effort even with the most talented engineers. But what if we could reduce the data required to a fraction? In this article, we’ll cover how transfer learning is making world-class models open source and introduce BERT (bidirectional encoder representations from transformers). BERT is the most powerful NLP “tool” to date. We’ll explore how it works and why it will change the way companies execute NLP projects.
