Professional Experience
Key Achievements
  • At Blueroof360 I revamped a legacy PHP monolith with React micro frontends, which became a crucial selling point for the company at a major US real estate conference in 2019.
  • At Tripadvisor I created and launched an experiment on a more user-friendly 'faceted search' homepage, tested with 10% of global traffic and worked in close partnership with Senior (Director level) management. The experiment was a success, and to this day is still the default search method and the first experience users encounter coming into Tripadvisor's homepage.
