Bio
Amr Shalaby
Over the span of five years in the field of data science, Peter Mendev was of the few Data Engineers who left a permanent impression and a void that was, and remains, difficult to fill. The methodic dilgence of rendering potentially unusable legacy data from 2010 to date into a Bi-Ready State is a self-sufficient testatment of Peter's skills. As the first Data Analyst in Skylight Health Group, all visualizations made, analysises compiled, and reports compeleted are based on Peter's ETL jobs. My success in establishing the statistical rigor needed for all studies made are, in all truth, would be nonexistent without scrubbed, cleaned, and production-ready data all stemming from Peter's work.
