ABOUT_ME.TXT

DESCRIPTION:

AI-focused software engineer with 6+ years building scalable systems. I write code that works, not code that looks pretty. Performance over aesthetics. Function over form. Results over rhetoric.

Specialized in distributed systems, API design, and database optimization and AI/ML. I solve problems with minimal dependencies and maximum efficiency.

PHILOSOPHY:

"No matter how complex the problem, there is always a simple solution."
