About
I am a senior full-stack engineer in Buenos Aires with more than 10 years of experience.
I work mostly in TypeScript, React, GraphQL and Next.js. I add AI to complex infrastructure, and I use Claude Code every day to build agents, workflows and skills.
I care more about the solution than the technology, and I like to build useful products, alone or with talented colleagues. I pay attention to detail, and if users do not find my solution useful, I go with their view.

- Built the platform behind Wrap (wrap.co) from scratch at an early-stage startup, on the MEAN stack (MongoDB, Express, Angular, Node.js), with user, team and permission management.

- Page builders
I use Claude Code every day. I build agents, workflows and custom skills with it, and I run parallel subagents.
I built page builders at R/GA and Monks, and I now own a third at Dialpad. They let people who are not engineers make pages on their own. At Dialpad, the Claude API writes the text inside the builder.
Earlier in my career I used the MEAN stack (MongoDB, Express, Angular and Node.js), and Java before that.
