"Walk by faith, not by sight"
Lifetime learner
I'm an Information Technology student who's curious about how systems actually work. Not just on the surface. I like breaking things down, asking questions, and learning across fields, from IT to professional audio systems. I'm detail-oriented, self-driven, and always looking to grow through real-world tech and practical problem-solving.
