I build things that look as good as they work.

I’m Jonathan Allegretti, a Full Stack Lead Developer based in Buenos Aires with 10+ years of experience. I’ve led teams building Web3 platforms, NFT marketplaces, SaaS dashboards, and more — currently Senior Software Engineer at Webflow.

I care deeply about clean architecture, great UX, and shipping things that actually work. When I’m not coding you can find me building side projects — trackers, QR tools, budgeting apps — reading or rocking some music.
