    Testimonials

    "Miss Rivera can be described as a hard working professional who is always looking for the next challenge, She is constantly recognized as a data driven analyst with a real world comprehension, that allows her to always delivered a sensate solution for the end user; this specific characteristic allow her to be promoted as a “Subject Matter Expert”. Her numeric sense is remarkable and the way she is able to communicate it is even better, The mathematics she puts into the table in some work meetings it is on the higher complexity side and she still delivers the correct message into the table, regardless of the mathematic knowledge of her coworkers. Miss Rivera has always showed herself as an independent high potential associate for Walmart and has always delivered her projects over the expectations initially requested.”
    Lic. Osvaldo Ibarra Solis
    Supply Chain Jr. Director.
    "I am very favorable impressed by her understanding and independence. Specially in her undergraduate thesis where she was worked very hard in develop numerical and asymptotic procedures. Her skill level in mathematics and numerics is very high, Abigail is able to participate in any project in Applied Mathematics due her knowledge in many subject in Celestial Mechanics, Qualitative Differential Equation, Numerical Methods, etc.”
