Buenos Aires - Remote worldwide

Hey, I'm Cristian.

I'm a senior full-stack product engineer focused on frontend-heavy product systems, performance, and real-time collaboration. I care about product judgment, strong execution, and thoughtful UI engineering in the same conversation.

About

I like product work where the interface and the system have to agree.

I am a senior full-stack product engineer based in Buenos Aires, focused on frontend-heavy systems, real-time collaboration, and product surfaces where performance and interaction quality matter.

My background moves from early company-building work into product engineering at Riverside. That mix makes me comfortable moving between product constraints, UI details, backend contracts, rollout risk, and the operational work needed to ship.

The common thread is ownership: understand the user workflow, choose the smallest useful architecture, make the product feel better, and keep enough technical discipline for the next team to build on it.
