He works at Electrical Engineering and Asset Optimization department. In his free time at home, he is passionate in pursuing INVBAT.COM since 2009.
Sam Ortega is now confident that he can remember mathematical formulas and equations that he created in INVBAT.COM within five minutes to help him do engineering analysis, design review, and make recommendation. He believes science, technology, engineering, arts, and mathematics (S.T.E.A.M) students, teachers, and employees worldwide will also need help to remember their own formulas and equations. He sees a business opportunity for creating customize calculator with embedded formula for other colleagues in S.T.E.A.M to help them have their own personal formula and calculator website.
