Fullstack engineer. Zero to one, AI agents and products.

Ignacio Pastor

I do my best work early, when there's an idea, a deadline and not much else. I've been the first engineer at two startups and led engineering at Somnia, a layer 1 blockchain, from devnet to mainnet.

Most of those years were in crypto, where a bug in a smart contract is permanent. Now I build AI agents: systems that plan, use tools and act, and the products around them. I am mostly interested in using AI to transform existing companies and industries.

About

The short version

I joined the crypto industry at the height of the NFT Summer in 2021. I worked to join videogame mechanics with a crypto economic layer on Improbable's vision of the Metaverse, where I built the would-be DAO treasury and governance system. Then moved to create various experiments (cross-chain identity prototypes on ERC-6551, dynamic-metadata NFTs, and a marketplace wired into Unity) as part of a newly created R&D section.

From there I moved over to Somnia, the fastest L1 ever, where I led engineering from devnet to mainnet. This was easily one of the most intense times in my career. I led a team of 5 developers, attended conferences as a speaker and supported 60+ ecosystem projects as they integrated for Somnia's mainnet launch. We also shipped the consensus and staking contracts that now hold over 20% of the SOMI supply, vesting smart contracts for investors, built the quest platform that verified and rewarded 95,000+ contributors, and put together everything else a TGE demands.

After Somnia I joined Charms as founding engineer. It was a consumer app where every AI companion had its own token and economy. I owned the on-chain side and made it feel like a normal app for people who had never used a wallet: embedded wallets, token launches with Clanker and cross-chain swaps across Base, Solana, and BNB.

These days I build AI agents and the products around them, and I still take on web3 work when the contracts are the hard part. I'm open to a founding or senior role on an AI product, and I take a small number of contracts through MoveSeventyEight. I write about what I build along the way.

Systems I designed and shipped to production

Agent that runs a marketing agency's client operations

Claude Code agent with MCP servers for Metricool, Google Workspace and the Business Profile API. It reads reviews and replies in the client's voice, builds the monthly social report and sends it, and drafts the weekly newsletter. Playwright where there is no public API. Non-technical staff install it with one command.

In production, running the agency's daily client work

Wallet infrastructure for AI agents

Embedded wallets and account abstraction for a consumer app where each AI companion has its own memecoin, and the trading fees pay for the agent's inference. Privy wallets, EIP-7702 delegation, and batched transactions turn a multi-step crypto flow into one tap, with no gas prompts.

Gasless, one-tap transactions across EVM chains and Solana
