Work History

Senior Data Scientist

Reddit
5 2021 - Current
  • Build optimization model to select top URLs with highest predicted click-through-rate for machine translation.
  • Built new set of ETL and dashboards for Reddit's top-line reporting using HyperLogLog++ functions that resulted in 83% reduction in computation times and 21% reduction in BigQuery costs per year.
  • Built a candidate selection model for curated push notifications using cosine similarity of users' interest and post topic. Improved click-through-rate by 0.4% by finding optimal candidates for each campaign.
  • Worked closely with cross-functional stakeholders and helped refined KPIs and prioritize resource allocation for engineering efforts.
  • Mentored and guided junior team members during onboarding and beyond to help them develop their skills.
  • Led operation research study groups for interested colleagues to learn about and collaborate on optimization projects

Data Scientist

Nordstrom
