Experience

  • Metadroner (Development)
    http://metadroner.com

    I built a search engine for drone and multicopter (mechanically simple aerial vehicle) parts, after getting involved with racing drones and getting frustrated with searching numerous stores for the hobby products I needed. This was built to serve a personal itch, and I'm proud to say that the small community received it quite well. It's grown to serve almost a thousand users.

    This project was a solo endeavor, and included building the following:
    • A Python-based web scraping infrastructure collecting data on over 25,000 products every day.
    • An advanced search engine leveraging Elasticsearch and a Node.js back-end.
    • A React single page app front-end.
