• Good knowledge of electronics and circuitry and deep knowledge and understanding of low-cost 3D printing, with a popular open-source book (in Brazilian Portuguese) published about it. Due to that, good modeling experience in open-source 3D modelers like Blender, FreeCAD, and OpenSCAD.

Objective

• Mostly due to my diverse set of abilities, my best performance is atmedium to long term projects with high stakes and responsibilities and unforeseen circumstances in DevOps environments.

• I thrive in complex systems environments with multiple languages, being able to learn a new one in a very short time. High skill in troubleshooting and fixing system problems and keeping things working even in emergencies.

• With my education experience, I am also very good anddocumenting and organizing computing environments.

• I can administrate diverse UNIX system environments including planning for high availability (certified in HACMP for AIX and with experience in other HA systems) and network topology and firewalls.

• I can code applications that complement a diverse environment, with scripting, VM-based or compiled languages.

• I can advise on open-source licensing and strategies.

• I can use my extra skills to complement work, e.g. 3D printing for embedded devices or 3D modeling.

• I can work the night shift if needed. Had a 5 years period at IBM with that.

• State University of Campinas (Unicamp), 2001. Computer engineering.

• State University of Campinas (Unicamp), 2010. Master in Genetics and Molecular Biology.

• Several certifications from Unixes:

  • SAIR Linux certification, 2001

  • CATE (Certified Advanced Technical Expert) for AIX, 2001.

  • HP-UX and Solaris System Administrator certifications.

• Many in-job courses and certifications, from ITILv3 to individual products like Lotus Notes and Maximo.

• Embedded development courses with Embedded Labworks and (now extinct) Tech training
