Software engineer · Supersolid cofounder

Hi, I’m Juli.Do you want to develop an app?

The world has changed. The complexity in engineering has shifted, and what actually makes a difference now are the people behind ideas and business processes.

My goal as an engineer is to bridge the gap between the idea and its implementation as swiftly, elegantly and robustly as possible, to bring amazing products and services, and thus the future, to life.

jtreks

Trekking guides & maps

Ascenso

Mountain simulation · Unreal Engine 5

Ascenso introduces fantasy, history and culture in beautiful worlds designed using real elevation data, myths and legends, and even real mountaineering skills. Through it, you’ll get an exciting glimpse into what it feels like to actually reach a summit, while learning how to do it and about the places where you’d do it on the way. It’s a complementary product to my other trekking / mountain related project, jtreks, which helps you plan trekking trips fast and easily with real, useful, properly sourced data. Currently in development, soon to release for early access.

Open source & personal tools

Solana Sniper

Rust · Open source

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.

IMHO

Real estate · Search

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.

Pushy

Rust · Notifications

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.

Hermes Thrice

Music · Audio · Visuals

Hermes Thrice Worlds brings together the musical, audio, and visual tools I build for my own creative process.

Personal toolkit

Experience

I’m from Argentina and have worked with consulting firms, startups and product teams across Argentina, the US and Europe.

Outside work, I spend time trekking and making music. A few of those interests have turned into projects of their own.
