Hey, I'm Julio 👋

About

Based in Brussels. Background in enterprise IT infrastructure (networking, orchestration, datacenter).

In my free time I build things at the intersection of AI, automation, and Web3 — not demos, but systems running on real hardware with real money on the line. I document what works, what breaks, and what I'd do differently.

→ build-log — public record of what I'm building

What I'm currently running

• Bitcoin pruned node — Bitcoin Core 27.2, mainnet, self-hosted
• Ethereum light client — Helios (a16z), local RPC proxy, trustless verification
• 4 algorithmic grid bots — EVM (Arbitrum, Base, Linea) + Solana, system cron, zero cloud cost
