I’m Erik.
I build software
and AI products.
I create products, agents and integrations that aim to be genuinely useful. My focus is private AI, data protection and governance: giving people control over how they use AI and what happens to their data.
What I’m building

Private AI & data protection
I specialise in private AI usage: deciding where models run, what data they can access, and how sensitive information is handled.
Agents & integrations
I build agents and connect them to APIs, internal tools and business workflows so they can do useful work.
Governance & control
I focus on making AI governable: clear permissions, human oversight and visibility into what a system is doing.
Products & automation
I work across frontend, backend and infrastructure to turn an idea into a product, or a manual process into a working integration.

A bit about me
From a small town
in Argentina.
I grew up in a small town in Argentina, surfing and skateboarding. I also made music, so “former rapper” belongs on the list.
I’ve always liked creating things. That took me into software, from teaching people to code to building apps, industrial integrations and now AI products.
I’m an AI enthusiast, and I care about making things people actually find valuable: products they use, agents that help, and integrations that make their work easier.
