About

I'm Hector Araya C., a senior developer and founder of HarayaDev, a Chile-based web and AI development studio. Over 7 years building everything from large-scale e-commerce (VTEX IO, Cencosud) to admin panels and end-to-end AI integrations. I lead every project myself, and bring in more developers from the team when the scope calls for it.

Today the studio runs two tracks: a productized line (AI-powered websites for Chilean SMBs, generated in hours with our own platform) and custom engagements — advanced development, integrations, and ongoing maintenance for teams that need more than a template (see work).
