Engineer witha designer's eye

I'm a senior product engineer with 10+ years building software for startups and enterprises in the US and Brazil. I'm at my best where messy data has to become an interface people find simple, and I own the work from the first conversation to production.

Professional Experience

Senior Software Engineer

1up, New York, US – Remote

12/2025 to Present

  • Built 1up’s public status page end to end, from signal collectors and daily uptime rollups to the public API and React app, after showing that 4 real outages would have left the originally requested 7-row design entirely green.
  • Designed a shared assignment model and moved 4 product areas onto it, retiring 2 legacy models with dual-write, backfill and staged cutovers so every step could be rolled back.
  • Built customer-managed custom roles (12 permission groups over 44 permissions) with a denylist that keeps Admin rights unreachable, closing 3 existing permission holes found along the way.
  • Automated assignment reminders across in-app, email, Slack and Teams with escalation and snooze, using a run lock and launch backfill so nobody receives duplicate or bulk notifications.
  • Finished and shipped the team’s Storybook, splitting a 9,700-line icon file into 265 components and adding shared modal, table, tabs and pagination components now imported in more than 40 places.
