2nd Place National Export Logistics Hackathon
https://www.youtube.com/watch?v=3YPQv-I3cC4National hackathon sponsored by Singapore. My team created a machine learning-driven platform to predict when ships would complete their load/unload schedule and recommend better port operational decisions. I set up all the servers, wrote the whole front end in React and back end in NodeJs with MongoDB, integrated the database with Metabase, created analytic dashboards, embedded the metrics on the front end, integrated the ML endpoint for predictions, and wrote crawlers on cron jobs to scrape the ships' statuses on the port's website.
