My Engineering Evolution

From writing my first line of C++ to architecting autonomous AI agents with custom languages.

The Foundation

2023

I learned to think in code.

Started my B.Sc. in Computer Science & Artificial Intelligence at South Valley National University. Laid strong foundations in algorithmic thinking, object-oriented design, and relational databases.
