Message

At Jungle Scout, I migrated a brand-visibility product to a new data source without customer disruption and retired its legacy scraping service, cutting infrastructure cost by about 40%. I also helped build an executive dashboard spanning its data pipeline and customizable UI.

I rebuilt Jungle Scout’s keyword research product across its API, data pipelines, and UI, and rewrote a legacy Ruby on Rails page to eliminate recurring bugs. More recently, I built an end-to-end feature showing sellers the Amazon search terms shoppers use, including a performance overhaul and load-testing setup.

At Humaxa, I designed and built Expert Finder, an AI-powered feature connecting employees with colleagues who can help, from database schema through the Microsoft Teams experience. I also built a mentoring program end to end and modernized the Teams product across its services, data layer, and React dashboard.
