I build full-stack production systems across maritime, lab operations, e-commerce, and telecom. As an independent contractor, I developed a Python/PySide6 maritime desktop application deployed across five vessels and an E2E automation platform that saves a five-engineer QA team roughly five testing hours daily.

Previously at Wisedu Education, I led six engineers building a campus e-commerce platform serving 10+ universities, 5,000+ SKUs, and 70,000+ yearly orders. I bring 10+ years of Java experience alongside React, Vue, Python, Node.js, cloud deployment, and end-to-end ownership from schema design to production.
