At TailinAbrasives Corporation, I developed an AI-assisted tool that turns PowerPoint and PDF presentations into narrated videos. It produced five departmental orientation videos and reduced delivery time from 1–2 hours to 15–45 minutes per session.

I also designed and developed a General Ledger web system to replace the company's manual accounting process, automating PHP/USD bookkeeping and journal entries. As a freelance software developer, I developed Outlay, an offline-first personal finance app, and Boundary Log, a local-first fleet operations web app.
