Full-stack engineer building real-time data, AI workflows, and tools people depend on: systems that stay reliable but feel effortless.
Things I'vebuilt & shipped.
An AI search platform for used cars in Argentina. It continuously scrapes and scores marketplace listings, then answers natural-language queries with vector retrieval and LLM ranking.
A B2B pricing-intelligence platform for retail and agencies. It monitors competitor stores, matches SKUs across catalogs, and surfaces price gaps so teams know when to move prices, with self-serve setup in minutes.
A real-time trading analytics platform that processes live market data, generates signals, ranks opportunities, and lets users monitor and interact with trading activity through a responsive dashboard.
A SaaS workspace and CRM platform built to manage tasks, workflows, records, and team operations through modular dashboards and flexible workspace logic.
An AI-assisted product designed to turn a user's problem, prompt, and evidence into a structured action plan or work guide.
More work available on request.

06About
I like building products the same way some people like making music or designing spaces. I care about the structure underneath, but also about the feeling it leaves behind. I'm a full-stack engineer from Argentina, and most of the work I enjoy lives in that middle ground between technical depth and creative instinct, where a system has to be reliable, but also feel effortless and well crafted.
I'm especially drawn to ambitious ideas, products with a lot happening under the hood (real-time data, AI workflows, automation, tools people actually depend on), but I always want the final experience to feel simple, precise, and human. That's the kind of work I want my name attached to.
