I'm a 30-year-old engineer from Argentina. I've spent the last eight years building applications for a wide variety of companies: large consulting firms, software factories, small startups and well established product companies.
From backend — Java and C# on the object-oriented side, Scala and Rust on the more functional one — to full stack (vanilla, React, Vue), DevOps with AWS/GCP/K8s, and AI engineering with Claude Code, Codex, and more. I've refactored large monolithic applications into microservice-oriented systems, built full-stack web applications from scratch, and set up productive agentive workflows for large corporations and small businesses.
I've worked solo, in duos and trios, and on teams as large as twenty — agile and not, at startups, consulting firms and product companies. I've also acted as product owner on my own builds: sitting with the client to work out what the thing has to do, then taking it from design to production, with the unit, integration and load tests around it.
This year I started the founder journey with Supersolid, together with my former boss and mentor Dmitry Sabanin and my best friend Emiliano Migliorata. We're building in fintech and quant trading, and we work with other founders as a cofounding team on their ideas.
I tackle problems methodically, and I make a point of relying on my team to move faster. I'm a big fan of failing fast, of automated TDD and CI/CD pipelines, and of delivering small concrete iterations. Simple problems or complex ones — I'm interested either way.
Every link opens the running product, not a case study about it. Two have no public URL yet, and say so.
The studio I started this year with Dmitry Sabanin, my former boss and mentor, and Emiliano Migliorata, my best friend. We build our own products, and we cofound with other founders on theirs. Almost everything below was built inside it.
An AI agent that has run unattended on a cloud VM since June, reachable through Slack and trusted with real infrastructure: watchdogs, nightly digests, incident detection, and a knowledge store it maintains itself.
What Supersolid is actually for. A Rust engine runs strategies against live books, a console watches every lane as it happens, and an expectancy solver prices the edge before any capital moves. It runs on our own money, which is the only test that counts. It has no landing page yet — that is the next thing I build.
Trekking guides where every claim is traced back to a government portal, a park authority or a peer-reviewed paper — 32 ranges, 243 articles, 3,403 sources. The 3D route maps are drawn from the same satellite elevation data as the Lanín climb below.
A social marketplace for the water: a live chart of boats, chat between guests, captains and providers, and a marketplace underneath it. Built API-first — every feature is a tested HTTP contract before a single pixel ships. On TestFlight since June.
A concierge for Ibiza. A WhatsApp agent takes a request in plain language — a table, a boat, a villa — and turns it into something bookable, with checkout attached.
Client work. Finished, handed over, and still running without me.
The software a beverage distributor actually runs on: route planning, customer records, order intake, collections, stock and Spanish invoicing. A field app for a phone in a van, an admin desk for the office.
An import platform for Argentine companies buying from international suppliers: catalogue, landed-cost simulator, wholesale orders and logistics, wired into MercadoLibre and Tiendanube.
A DJ school and sound rental house in Buenos Aires. Courses, equipment and bookings, in Spanish, for a business that lives on its reputation.
A Rust service that subscribes to Raydium logs, filters initialize2 events, pulls the mint out of the transaction and fetches its metadata before the token is listed anywhere useful. It also profiles holder distribution, which is the cheapest way to tell a launch from a rug.
AI real-estate search for Argentina. Scrapers behind rotating proxies feed a natural-language pipeline where a second judge model scores every extraction before it is allowed to count. A WhatsApp agent turns free-form Spanish into structured queries. The Python backend was rewritten in TypeScript at a quarter of the size, and that cut is the part I would defend.
Open →A notification system built for crypto exchanges. Rust and Axum at the front, a background worker behind it, Postgres and Redis underneath, SQS for the queue and Contentful for the templates, so marketing ships copy without waiting on a deploy.
A playable climb of Volcán Lanín, 3,776m, in Unreal Engine 5. Real terrain from satellite elevation data, the real Tromen route from OpenStreetMap, and hazards taken from having actually summited it. The same elevation file feeds three things: this game, the map on jtreks.co, and a 3D-printed keyring.
Autonomous agent infrastructure, a Rust trading platform, and client product work.
Platform engineering across Java, TypeScript, Scala and Go. AuthZ platform on AWS Cognito; CI/CD with Kubernetes, Helm, ArgoCD; revenue-driving payment features.
Portfolio management for IHS Markit: APIs and data pipelines for capital-intensive markets, event-driven architecture.
String3, a Layer 1 blockchain on the actor model. Joined as support, left as lead.
Daruma electronic wallet, end to end.
Reactive microservices for Latin America's largest e-commerce platform. Akka Typed, Persistence, Streams, Cluster Sharding.
Microservices for Disney; energy-sector services for Mosaic.
Backend, platform, or an agent that has to hold on its own. I'm in Buenos Aires and I've worked remote with US and UK teams for most of eight years.
