Sr. Software Engineer · Mercado Libre · iOS · Android · Web & backend

I build scalable platforms for millions of users across Latin America — with strong foundations in architecture, performance, accessibility, and UX. Server-Driven UI and reusable systems are what keep me curious.

01 — ABOUT

Mobile-first, full-stack when it matters.

I'm a software engineer specialized in mobile (iOS), building solutions that span frontend, backend, and cross-platform ecosystems. I work primarily with Swift and Objective-C, and I'm fluent in Kotlin, Java, Node.js (Express), Python, JavaScript, and SQL / PL/SQL when the problem calls for it.

I care about scalable architecture, performance, accessibility, and user experience. I'm especially driven by Server-Driven UI, reusable systems, and large-scale migrations — the kind of work where good boundaries and clear ownership actually show up in the product.

04 — GITHUB

Private on purpose.

My GitHub is entirely private: unfinished side projects, experiments, and repos I keep for personal goals — not a curated public portfolio.

The professional signal I want to share is on this site (Experience and Stack). For anything beyond that — how I think, tradeoffs, fit — email or LinkedIn work better than an empty public profile.

Coming soon: demos of standout personal work and select client projects I can show publicly — I'll share them here when they're ready.
