Steven Siciliano
I make operational data accurate enough to act on. Nine years reconciling cargo records for the U.S. Army, then building Kelm Media's first database to replace paper files. Today I apply that to supplier pricing and inventory at Fragrance.com while completing an M.S. in Data Science at Purdue.
