About Me

Hello! I am Lucas, a Information Systems student at UNOESTE (6th term) and Software Developer in the accounting/fiscal sector. I have solid experience in process automation using AutoHotkey, Python and C/C++.

My focus is on creating solutions that optimize real workflows — from automatic tax note correction to complete systems in Java. I am also driven by low-level challenges, with projects in C and C++.
