Summary
This profile lists the activities carried out during the last 20 years as a systems developer and architect using software and hardware engineering procedures. Such activities had the necessary technical and theoretical foundation in the research and industrial areas built over another 20 years of intense work in technical support and consultancy to several companies in different countries and cultures.
The data presented in this profile is supported and interrelated to a base of source code of applications and engineering diagrams used as a demonstration of instruments and systems developed and in operation on laboratory benches today.
Once reviewing the document, use the internal links in the skills panels to navigate to the activity you will find information that supports the declared skill.
From there, you can use the external links to access the respective source code repositories / engineering diagrams, course completion certificates, and published peer-reviewed work that support the activity.
As the task of balancing between precision and synthesis in describing 40 years of intense work in several technical areas is enormous, two documents are provided. This the compact version.
