I am Operations Research Enginner and Data Scientist
My main areas of work are Mathematical Programming, Combinatorial optimization and Data Analysis
About me
I enjoy to tacke the complex problems from supply chains and others areas.
I am Research and Development Engineer at See-d since january 2019. I obtained my degree in engineering mathematics at Escuela Politécnica del Ecuador. I received my Ph.D from Université de Bretagne-Sud.
I love to solve the complex problem and find better solutions throught metaheuristics and IA. I always try my best to make user interface using web apis, dockers and web technologies like angular.
Deal with complex issues
For solving complex problems in various fields, I apply four main steps :
- Understanding of the issue through discussions. Determination of objectives and constraints
- Mathematical modeling of problem and analysis of possible solutions
- Study and implementation of solving algorithms like metaheuristics or Artificial Intelligence algorithms
- User interface development and writing of a technical report
