Juan AlmeidaFull Stack & AI Engineer

Hello World

I build AI systems, automations, and applications that ship.

What I bring

// about

I'm a full-stack engineer who builds end-to-end — from data pipelines and AI integrations to the interfaces people actually use. I've shipped search platforms handling millions of records, courier logistics systems, and machine-learning workflows that run in production.

My work sits at the intersection of product thinking and engineering depth. I don't just write code; I figure out what needs to exist, then build it. TypeScript, Python, React, Django, cloud infrastructure — I pick the right tool for the problem, not the other way around.

I care about software that works reliably, scales gracefully, and solves real problems. No over-engineering, no hype — just useful things, built well.
