The longer story.
I'm Ignacio, a developer in Madrid. I studied economics, learned machine learning, spent five years building crypto systems, and now build AI agents.
Along the way I helped build two startups, was part of the R&D department of a major UK gaming company, and led the technical team of a new layer 1 blockchain we built from the ground up. I've built dozens of MVPs, products and internal tools. I enjoy learning new technologies and pushing myself to apply different tools and techniques to the problems that come up.
How I got here.
I started in economics and international business. In 2020 I went deep into programming and the more technical parts of my work, and ended up going back to school for a master's in machine learning. A year later everything came together: NFT summer arrived, and I started writing smart contracts for clients as a freelancer and competing in hackathons around the world.
In 2022 I co-founded Gokaden in Station F's incubator and built its first prototype, the Forge, where an image model drew the art for each NFT. That summer I also joined Improbable to build the contracts behind its metaverse: a DAO treasury and governance system, and research prototypes like cross-chain identity on ERC-6551 and an NFT marketplace a game built with Unreal could plug into.
Improbable then built Somnia, an EVM blockchain, and I became its Head of Engineering. For two years I led a team of five from the first test network to mainnet and the token launch. We shipped the staking protocol that now holds over 20% of the SOMI supply and the quest platform that rewarded 95,000 community members. I was the technical contact for the 50+ projects building on the chain. I also built a custom interface for Safe's multisignature wallets, web3 video games and NFT collections. I spoke at conferences too. It was the most intense stretch of my career.
In January 2026 I joined Charms as founding engineer. Every AI companion in the app had its own token, and the agent could pay for its own inference from its trading fees. My job was to make the crypto invisible to the user: abstracted wallets that open with one tap and never ask for gas, token launches, and swaps across Base, Solana and BNB.
Since July 2026 I still build in crypto, but my focus has shifted to AI agents, internal tools and websites for small businesses, agencies and startups. On the side, I build my own projects under the name Move78. What I enjoy hasn't changed since my first gig: working on the first version of something, defining the vision for how we're going to build it, and then making it real.
