engineer ✦+13y codinghey, i'm marcelo.
i'm an end-to-end product engineer from asunción, paraguay. i lead frontend innovation for a north american utility company with fortune 500 clients — building real-time saas at enterprise scale — and i'm the founder of nderoga and grumi.
my passion for tech started early — reverse-engineering online games at twelve. more than a decade later, i still love the full loop: design, frontend, backend, infra, and the awkward tuesdays where the database needs a vacuum.
