§ 01 · About

About.

I'm a senior full-stack engineer based in Santiago, Chile. Over the past decade I've built web platforms, developer tooling, and distributed systems for products used by millions — at MakerDAO SES, Evernote, Fleek, Groupon, and ComparaOnline.

Recent work spans AI-powered features (LLMs, RAG, tool-calling agents) shipped to production and wallet-based identity infrastructure (EVM, DID, signature flows) powering DAO tooling. I shipped Evernote's first AI-powered feature — AI Note Cleanup — and now own core architectural pillars of Powerhouse, MakerDAO SES's DAO operations platform, where I also shipped features on Renown, its wallet-based identity + credential SDK.

I work at the intersection of AI, product engineering, and Web3. Before software, I trained as an accountant — a background that still shapes how I engineer: numbers should reconcile, invariants should hold, and the details are rarely negotiable.

Currently

Senior Software Engineer at MakerDAO SES, owning core architectural pillars of Powerhouse — a DAO operations platform — across ~2,100 commits. Day-to-day spans design-system ownership, wallet-based identity work on Renown, and heavy use of Claude Code to move fast across the monorepo.
