At Capital One, I modernized Teen Checking in the Android app by migrating two legacy screens to Jetpack Compose and building two Kotlin screens released to production. I also integrated automated accessibility testing and added visual regression tests across themes, orientations, and device sizes.

At Capital One, I built a Vue.js and TypeScript rule-authoring interface that cut authoring time by 33% for 14 engineers. I added validation, a drag-and-drop editor, local persistence, and a Vitest suite that reached the enterprise-standard 90% coverage threshold.

At the New York State Insurance Fund, I wrote IronPython scripts to extract and export Spotfire data to Excel, replacing a manual reporting process for 20 users. I also authored SQL queries for Data Governance and Catalog compliance research.

I'm building Dance Sync, a web app that aligns slowed-down dance practice videos with the original track. Its alignment engine recovers playback rate and start offset within a 50ms tolerance, and I'm developing the FastAPI backend and React review UI.
