About
I am a junior programmer with experience spanning game development and enterprise systems. I have led and built game projects in Unity as a main programmer and game designer, and I have worked as a junior mainframe developer using COBOL on the z/OS system.
I have a background in IT education and have taught programming to children. I thrive in teamwork, value time management, and enjoy blending technical precision with creativity to build well-designed software.
