Summary
🤩
Rockstar🎓
Top SchoolWilliam Lanchantin is a Principal Engineer with nine years of experience building the real-time logistics platform at CargoSense, where he progressed from data technician to data scientist and now owns core application code. He brings a strong analytical foundation from dual degrees in Electrical Engineering and Mathematics at Virginia Tech and early R&D experience at General Dynamics, including quantum computing experiments and ML for network intrusion detection. William combines data science and production engineering skills—Python, Elixir, Postgres, Phoenix/LiveView—to deploy predictive shipping models and maintain a low-latency visibility engine. He’s an active open-source contributor to the Absinthe GraphQL toolkit for Elixir, improving variable type validation and test quality to strengthen GraphQL reliability. Known for translating research-stage feasibility work into production-ready systems, he’s equally comfortable refactoring backend libraries or dabbling in front-end polish to deliver end-to-end shipping insights.
