My work, year by year.

Five years — three startups full-time, 10+ freelance clients, one patent. Written so a non-engineer recruiter can skim it in under a minute.

Senior engineer (contract)

Tavolo · US restaurant-marketing startup · remote
  • Owned the main product end-to-end — how restaurants sign in, build campaigns, approve and publish them.
  • Rebuilt the video-upload flow so a 2-minute phone clip on bad wifi reliably makes it to the cloud. Far fewer failed uploads.
  • Built the email-sending pipeline that serves 70+ restaurants. Tavolo publicly cites less than 1% monthly churn and 3× customer ROI.
  • Shipped an AI tool that cuts hours of customer-list work down to minutes.
