I started my programming career creating line of business applications for investment banks and slowly transitioned into web development roles working with Ruby on Rails and Elixir/Phoenix. I have experience working on high-profile web apps serving millions of active users and also smaller websites with modest traffic but terrific revenue. For the past eight years, I've been working remotely for American companies, mainly doing web development and playing tech-lead roles in several projects. I'm used to working with founders and CTOs, going from Plan A to Plan B to a plan that works. I've helped companies build MVPs, scale projects, and maintain large-scale systems handling millions of requests a day. I'm comfortable doing code reviews and pair programming sessions. These are some web apps I've worked on in the past couple of years: * [Canary Data (Elixir/Phoenix - React)](https://canary-data.com/) * [Blitz (Elixir/Phoenix)](https://blitz.gg/) * [Superkind (Elixir/Phoenix)](https://www.linkedin.com/company/superkind) * [About Fresh (Elixir/Phoenix)](https://aboutfresh.org/) * [AR Workflow (Ruby/Rails - Node.js)](https://arworkflow.com/) * [SnapCell (Ruby/Rails)](https://snapcell.us.com/) * [Walkboard (Python/Django)](https://www.walkboard.com/) * [Sky Sports (Node.js - Python)](https://www.skysports.com/football) I wrote [Data Structures From Scratch](https://www.amazon.com/gp/product/B07MZZT6SW), an ebook about creating essential, advanced, and persistent data structures using the Ruby programming language. I live in Buenos Aires (UTC-3) with my wife and beautiful son.
