Demo profile

Full-stack Developer - B2B SaaS Products

Mendoza, Argentina·6+ years·Spanish / English

Bio

I build software for businesses, which means complex permissions, audit logs, and multi-tenant architecture. 6 years shipping admin panels, reporting dashboards, and integration APIs. I understand that B2B users need reliability and support over flashy features. Bootcamp grad who fell in love with backend complexity. My code is boring and that's a compliment. Great async communicator, timezone-flexible.
