The "edsa" Story

The domain edsa.tech is a nod to EDSA (Epifanio de los Santos Avenue), the longest highway in the Philippines and a monicker of my uncle Epifanio. As someone whose name also starts with E (Eugene De Los Santos), I chose it to represent my journey—a continuous highway of learning and building.
