About Me

A practical learner who enjoys figuring out how systems work.

See more

I am a technology apprentice with an associate degree in Mobile App Development. My interests include software and hardware testing, Linux administration, server infrastructure, automation, and technical documentation.

I learn best by building. Outside of work, I am developing a homelab called Nexus Lab, practicing Bash, managing self-hosted services, and documenting what I learn.
