Bernardo Zubko

Welding Specialist · Pine Ridge Reservation · Black Hills, South Dakota

I stitch metal on the edge of the prairie. Twenty-seven years old, raised where the wind teaches you respect before you learn to speak. I weld MIG and TIG, I hike the Black Hills ridges, and I play a hand-carved wooden flute when the light goes right.

This is a workshop log — not a portfolio. Field guides, calculators, film, and notes from the bench. The kind of thing I'd carry in my helmet case.
