Chester Zelaya

I am tech entrepreneur from UC Berkeley, specializing in the fusion of hardware and machine learning. A proud native of Costa Rica.

I've personally led advancements in interactive holograms, traceable supply chain solutions, and healthtech algorithms. Pursuing a B.S in both M.E and EECS, my ambition is not just to engineer, but to envision and mobilize ideas to redefine contemporary benchmarks.

“The secret of realizing the greatest fruitfulness and the greatest enjoyment of existence is: to live dangerously!" -Nietzsche
