What I'm looking for

I seek roles combining systems administration and software development where I can lead migrations, optimize infrastructure with virtualization, and build scalable web and ERP solutions in collaborative, growth-focused teams.

I am an Informatic Engineer with extensive experience designing and developing management systems, implementing virtualization, and administering Windows and Linux networks. I have delivered production web projects, led migrations from proprietary to free software, and developed backend systems in C#, Python, Django, and Odoo.

I combine systems administration, full-stack development, and IT project leadership to improve operations and reduce costs. My notable achievements include building company management systems (C#, ASP.Net MVC), Odoo module development, virtual classroom and CMS implementations (Moodle, WordPress, Drupal), and managing server virtualization with VMware and Proxmox.
