§ 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 has centered on AI integration: LLMs, RAG, agents, and embeddings shipped into product features and developer-productivity workflows. I contributed to Evernote's AI Note Cleanup — its first AI-powered feature — and now build Powerhouse, a Web3 platform, at MakerDAO SES.

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

Frontend Engineer at MakerDAO SES, building Powerhouse — a Web3 platform for DAOs and ecosystem actors. Day-to-day work spans AI integration (LLMs, RAG, agents) and product engineering.
