03 / SYSTEMS · LABS

The systems behind the products.

AI and automation as part of the engineering system — with context, explicit checks and repeatable delivery.

01AI / ENGINEERING

Harness.

A repo-native operating system for coding agents: scoped context, skills, deterministic checks and durable handoffs.

04 / ABOUT · APPROACH

I turn ambiguous problems into systems that ship.

Software engineer based in Rosario, Argentina. My background crosses electronics, programming and systems engineering. That mix shapes how I work: understand the system, simplify the product and ship something real.

ELECTRONICS → PROGRAMMING → SYSTEMS ENGINEERING

SYSTEMS FIRST

Architecture before decoration.

Business rules, data and failure modes come before unnecessary abstraction.

PRODUCT THINKING

Useful beats impressive.

I care about the shortest path from a real problem to a product people can actually use.

AI-NATIVE DELIVERY

AI belongs inside the workflow.

Agents, skills and automation are useful when they inherit context and pass explicit quality gates.
