## About

```text
At WiseTech Global (e2open), I took ownership of Fusion API and Fusion Service for e2open Global Parcel. I extended carrier integrations and the tracking pipeline, which processes files from about 80 carriers.

I also brought a testing approach to another team’s untested components; my team cut open bugs by 60% in six weeks. Earlier, I built and maintained financial workflows at SURA Mutual Funds, including fund distribution, commission, and banking systems.
