VantLabs is the brand through which
I build software for Latin America.
Not a company, not an agency. It's the structure Efrain Hernandez — software engineer, sole individual — uses to design, build, and maintain useful digital products for Latin America.
VantLabs comes from a simple observation: in Latin America, millions of people are wrestling with concrete problems —accessing justice, understanding their money, fighting a parking ticket— for which software could be a huge tool. But the products that reach them are designed for another market, another language, another reality.
So I decided to stop complaining and start building. I work alone — and that's not a weakness. It means every decision passes through one mind, the quality bar doesn't get negotiated in a meeting, and every product gets the focus it needs to become exceptional.
When a product grows enough to justify it, I'll bring people in. But the principle stays: few things, well made, defensible in every detail.

My core convictions
Mission over metrics
Metrics are tools to understand impact, not the reason to exist. If a metric goes up but the product gets worse, the metric is wrong.
Quality as a habit
Every commit, every pixel, every query. Quality is not delegated or pushed to the end — it happens at every step or it doesn't happen at all.
Building in public
I share what I'm working on, the decisions I make, and what I learn along the way. Transparency makes me better.
Latin America first
My products are designed for Latin American reality: languages, currencies, response times, payment methods, legal frameworks. Not a secondary market — the market.
What I'm building today
Platform that generates legal documents with AI — tutelas, petitions, ticket appeals — in under 5 minutes. Already in closed beta.
