About me
As an engineer I started my professional life developing temperature and pressure sensors for harsh environments and performing devices electrical characterization. At that time, which was 9 years ago, I used to program in MATLAB and C for solving engineering problems, plotting graphs and automating measument equipment mostly. Later I started learning Java because I wanted to build programs with graphical interfaces. Than I got another job in a startup company designing analog integrated circuit blocks for energy harvesting devices. There I had the chance to work on Linux environments in a professional way, and to learn how to use Version Control Systems, such as SVN and git. After that, I started a company of my own. I've been working on watering systems for kitchen gardens using Raspberry Pis as the main controller, programming in Python, using Flask as the web framework, Docker to manage and update devices, and frontend interface development.
I may introduce myself as an electrical engineer, hardware/software developer, guitarrist, audiophile and agroforestry devoted guy. Arts, nature and technology thrills me. And I'm always looking for using them around.
