Qwant 2017-09-04 — 2018-12-01

Data Engineer

Qwant is a search engine that does not track its users. It has the largest web index in Europe, the quality of which I contributed to. I was a member of the core 'data' team, working on the company's web crawlers, databases (indices), and data analysis tools.

Highlights

  • created a machine-learning model for the classification of user searches (using distributed word-embedding and clustering in Spark)
  • Contributed to the crawlers, fixed many data-quality issues.
  • Built data visualization tools.
