Cláudio L., Linux Engineer

Summary:

• Wrote a book using Asciidoc: https://github.com/Patola/ebook/

• Versatile system administrator and developer graduated in engineering with decades of UNIX and Linux experience in big customers with mission-critical environments, working with servers, desktops, mobile and embedded devices.

• Language generalist with programming experience (complete application writing) in C, C++, Java, Perl, Python, SQL, PHP, and shell scripting.

• Good knowledge of revision control systems like git, RCS, Subversion (SVN), CVS, and bazaar.

• Good knowledge of container virtualization (docker, vagrant), configuration management (puppet, ansible), cloud (Softlayer, AWS), with limited experience with orchestration (Kubernetes, docker swarm).

• Experience in programming with various general use libraries/packages such as libcurl, berkeley db, sqlite3, Redis, rabbitmq, scrapy, gettext (for internationalization), mysql, PostgreSQL, oracle, MS SQL Server.

• Knowledge and experience with Agile methodologies, LEAN, and ITIL, including extreme programming (XP), Kanban, and SCRUM; ITILv3 certified.

• Deep understanding of open-source licenses, philosophy, and legislation and active contributor to open-source projects.

• Knowledge and experience in packaging software applications in formats like deb, rpm, lpp (AIX), AppImage and snap.

• 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 at medium 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 and documenting 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.
