Experience

  • SCIPHER
    https://www.eversana.com/products/actics/

    I acted as the lead architect and manager of the team that built SCIPHER, a web-based SaaS cloud application that allows brand managers to quickly run canned analytics on claims and EMR data while giving data scientists a platform to run custom AI/ML models. The application was deployed on AWS using a Vue.js front end and C# .NET back end, used PostgreSQL for application data and Snowflake for warehouse data, and ran AI/ML models using Python in Docker containers.

  • PRDICT

    I was the primary front and back-end developer and ultimately hired the rest of the development team that built PRDICT, a web-based application designed and built in collaboration with a Fortune 500 client. PRDICT enables users with no data science background to run predictive analytics on Share of Conversation, based on models that tie custom ontologies with multiple social media corpora. The application was built and deployed on the AWS public cloud using a React front end and Python and Django back end, used PostgreSQL for application data storage, Neo4j for graph database storage, and ran ontology mappings and predictive analytics asynchronously using a dedicated pool of EC2 VMs running multiple Python processes.

  • EDGEHome

    I designed and wrote most of the firmware and controller software for the EDGEhome home automation solution. EDGEhome provides consumers with real-time energy monitoring and control of every home electricity usage point through a modern and intuitive user interface. The system comprises low-cost wireless devices that replace the home's outlets, switches, and electrical boxes. A wall-mounted tablet and mobile apps allow homeowners to conveniently monitor and control electrical usage and lighting throughout their home.

    As the head of software engineering, I had the final responsibility to create and execute the software product roadmap for the EDGEhome home automation portfolio. I designed, implemented, and tested the device software, including modules for device discovery and provisioning, message routing, firmware upload, software image management, message encryption, and device authentication. In addition, I implemented Agile software methodology, repeatable build practices, and automated test frameworks across all of the various code bases we used.
