SQL, EXCEL TUTOR. 20 years in analytics, now teaching and tutoring.
After twenty years in the business world working as an operational analyst, I have left my cubicle behind and have pursued education. I really have made a great move for myself as I love tutoring and teaching; I get to work from my home and I get to do what I really enjoy doing. Working in Analytics, I worked heavily with data and databases. I think I have spent most of my working career in MS Excel and have done innumerable things with it. In my work, I was always searching for answers, and SQL is the key computer language to know when looking for data. SQL is deceptively simple and yet so powerful, and I really enjoy using it.

Supporting US- and Mexico-based contact centers, I managed the Voice of Customer (VOC) program for operations. I managed, reported, and presented on feedback given to us by our customers through surveys in various communication channels (phone, email, paper, and web). I translated customer feedback into KPIs and actionable analytical insight and presented these KPIs and analytic recommendations to the C.O.O., VPs, and Directors monthly.
