Business Consultancy

I occasionally work as an independent consultant in applied mathematics, specially in operations research and optimization models.

The list below includes some of these real world problems. In most of them, I was also coordinating a small team of experts.

• TimeFiler (New Zealand and Australia)

- Analysis and correction of a previous MIP model for a nurse rostering application

- Formulation and implementation of new constraints

- Technologies: Gurobi MIP solver, C# programming language

• Vale S/A & Instituto Tecnológico Vale

- Professional training in Gurobi and Python.

- Software development: three matheuristic frameworks.

- Software development: optimization tool for daily sequencing in the exploitation of mining blocks (planning and quality control).

- Technologies: Gurobi MIP solver, Python programming language.

• Santa Casa de Misericórdia de Maceió

- Case study in formulations for the nurse scheduling issues of the hospital.

- Technologies: CBC MIP solver, Python programming language.

• Pickmeapp

- Case study within a Brazilian startup, designing algorithms for a real-world vehicle routing problem, further complicated with (i) on-line, (ii) vehicle capacity, (iii) time-windows, and (iv) pickup and delivery constraints.

- Technologies: SYMPHONY MIP solver, problem-specific heuristics, Python programming language.

• Group of Professors from the Department of Computer Science, Universidade Federal de Minas Gerais

- LP Formulation and development of a free tool to solve a transportation problem arising in healthcare planning.

- Technologies: GLPK solver, AMPL language, C++ programming language.
