Work Experience

Senior Frontend Engineer (Contract)

Aug 2025 - Oct 2026

1y 2m @Autodesk

construction tech · Remote

  • Shipped 30+ features and fixes in a shared React component library used across enterprise construction products (dropdowns, autocomplete, inline editing, tags), including keyboard accessibility and a WCAG contrast fix (2.61:1 → 7.69:1).
  • Designed a typed design-token contract (intent-based colour tree shared by all themes) and drove two product applications off the legacy theme (400+ call sites; the second finished by a teammate), with lint rules banning the old API.
  • Led the library migration to a new design-system generation across 59 component families, verifying each migration wave with style dumps so existing themes stayed byte-identical.
  • Cut 452 kB (-61%) from what micro-frontends bundle when importing the shared styles package, and fixed theme performance regressions, including the theme being rebuilt on every render.
  • Built multi-theme visual regression testing in Chromatic and improved release reliability: incident post-mortem, a self-healing CI job, and a fix for releases that silently skipped publishing.
