The most amazing... I've developed was an open-source framework for developing reusable numerical methods for physical simulations.


  • Senior Software Engineer

    2019 - PRESENT
    Precis Digital
    • Created the CI stack for the Python services.
    • Configured and maintained Kubernetes clusters.
    • Developed Python services and applications.
    Technologies: Django, Linux, REST, Kubernetes, Docker, Python
  • Scientific Computing Researcher

    2014 - PRESENT
    • Enhanced the software process used in the research group by employing scrum techniques such as sprint planning and review, the creation of project backlogs, and more.
    • Developed Elliptic, a type of open-source software for prototyping and developing numerical methods for physical simulations.
    • Selected the software stack used in most projects (Python, MOAB, and Trilinos), and trained the team developers to use it.
    • Explored Python's ability to inter-operate with libraries based on lower level languages, such as C/C++. Helped build PyMOAB, a wrapper for the open-source MOAB library, which uses C/C++ and Fortran.
    • Used Docker to package the developed software so that it is easier to deploy and use. Also trained the team on how Docker works and how to use it.
    Technologies: Docker, Linux, C, C++, Python
  • Software Engineer

    2016 - 2016
    • Rebuilt a full website from scratch using Django-CMS. The old website was built on Pelican, therefore Django-CMS brought more interactivity and made it possible to create and edit content more easily and visually.
    • Created a natural language processing tool with Gensim and Scikit-learn for suggesting if a given text is duplicated somewhere else in the database, from its extracted meaning.
    • Built automated software testing suites for Django backends and machine-learning software using pytest.
    • Employed Agile methodology practices on a daily basis.
    • Handled performance optimizations for several CPU-bound procedures on the server. Used Celery as a distributed queue for handling asynchronous CPU-bound tasks.
    Technologies: JavaScript, Python, Linux, REST, Bootstrap, Scikit-learn, Gensim, React, Django
  • Software Engineer

    2015 - 2015
    • Built the company's full website using Joomla!, JQuery and Bootstrap.
    • Developed several Joomla extensions for dealing with specific business needs.
    • Worked together with the client to model all the business rules and several requirements for the project.
    Technologies: Bootstrap, jQuery, Joomla


  • PyMOAB

    The Mesh-Oriented datABase (MOAB) is an open-source library for representing and storing meshes used on physical simulations built with C++.

    I helped build the PyMOAB interface, which provides bindings for accessing core functionalities from Python.

  • AmpliEdu

    AmpliEdu is a project built for the Intel Embedded System Design Invitation Contest, held in China in 2016. The project consists of an embedded system capable of turning any conventional multimedia projector into an interactive, touch-enabled projector.

    It used Node.js + Express to handle API requests for the rest of the system. Its image detection algorithms were prototyped with C/C++ and then implemented in an optimized hardware description language (Verilog).

    For the project, I was awarded the second place against several dozens of universities around the world.


    ELLIPTIc, The ExtensibLe LIbrary for Physical simulaTIons, is a library/framework for prototyping, testing and running large-scale physical simulations.

    It is built on top of Python and uses the PyMoab and PyTrilinos libraries to handle the internal mesh data structure, and matrix solving, respectively.

  • Python User Group Talks

    I have done two talks for my regional Python User Group conference:
    • Cython: Accelerating your Python
    • Building websites with Django-CMS

  • TCKE

    TCKE was a project for helping visually impaired people to orient themselves when they are inside buildings. One of the main applications was helping while shopping at stores. The system used state-of-the-art IPS (indoor positioning system) technology and was distributed as an Android app.

  • onDaF Simulator

    A simulator for the onDaF german test written in C++ and Qt 4. This project became quite famous among students who were pursuing a proficiency level for student exchange programs.

  • PedroNeto Hortifruti

    An eCommerce for selling agricultural produce built in 2015. It was built from scratch using Django in the back-end and jQuery in the front-end and had automated deploys with Docker.

  • Introduction to Python Microservices With Nameko (Publication)
    The microservices architectural pattern is an architectural style that is growing in popularity, given its flexibility and resilience. In this article, Toptal Freelance Python Developer Guilherme Caminha will focus on building a proof of concept microservices application in Python using Nameko, a microservices framework.
