US | Fairfax, CA
As a data scientist, I specialize in all parts of the typical automated data workflow. This usually consists of:
1. Parsing log files and architecting data in HDFS and data warehouses such as any of the major columnar stored databases, e.g. Vertica, InfoBright, Redshift, Impala, Presto, or traditional MySQL, Postgres, or NoSQL.
2. Automating reporting and statistical analysis such as forecasting, recommendations, KPI optimization with R, MATLAB, SPSS, etc.
3. Outputting the results in reports and dashboards with visualization tools like d3.js and other JavaScript extensions.
The top priority is always speed, efficiency, and automation.
