What I Do

Mobile Development

Native and cross-platform apps for iOS and Android. From architecture to the App Store.

Backend Systems

Scalable services in Go, Elixir, Ruby, and Python. API design, microservices, and data pipelines.

Engineering Leadership

Building and growing engineering teams. Defining processes, mentoring, and driving technical strategy.

Product Engineering

Data-driven development focused on user impact. Amplitude, A/B testing, and shipping what matters.

About

Software engineer with a broad trajectory — from native mobile development to backend systems in Go and Elixir, to leading engineering teams. I care deeply about product quality, clean architecture, and empowering the people I work with.

Currently at Barkibu, building the tech behind pet health insurance. Previously at Cabify, where I grew from mobile engineer to engineering manager for the Logistics division, shipping a delivery service from scratch.
