Experience
  • Adly (Development)
    http://adly.com/

    I was the first developer of Adly, a previous startup from Sean Rad of Tinder.

    My duties included the architectural design of the system and the development of the first version and then, when more people was incorporated to the team, I continued working as the Tech Lead until the company moved entirely to the US.

    We used Python, Django and SQLAlchemy; the requirements included several types of users interacting on the same platform, integration with the Twitter API, payment gateways, automated emails, etc.

    Most startups fail within the first years but this one is still operating, I'm happy to have been part of that success.

  • VotaUY (Development)
    http://www.votauy.com/

    A small website to provide information to Uruguayan voters during elections, it is intended as a backup of the official website which often becomes unavailable due to traffic spikes.

    The goal was to be highly available with minimal resources, so we designed it as a SPA using AngularJS served from a static HTML file with pregenerated JSON indexes in order to transfer the load from the server to the clients and maximize cacheability.

    There's also a collection of scripts that retrieve the official PDFs and generate the JSON indexes for the app.

    Source code available at https://github.com/git2samus/ce

  • xpost-bot (Development)
    https://github.com/git2samus/xpost-bot

    An automated scanner and user simulator (bot) for Reddit, it looks for particular keywords on the submissions by the users and creates links to those that match other parts of the site.

    The goal is to automatically get references to topics that might be of interest to some communities (subreddits) which are being discussed elsewhere on the site.

    It's written in Python and uses the PRAW library to interact with Reddit's API.

  • reddit-comment-animation (Development)
    https://github.com/git2samus/reddit-comment-animation

    A userscript (a JavaScript snippet for Greasemonkey) that recognizes a certain pattern on the comments at Reddit and converts it to an animated sequence.

    The idea originated from some comments that explained a set of steps to be followed, with this script those comments become something similar to a screencast in which you actually "see" the sequence step by step.

  • dupes (Development)
    https://github.com/git2samus/dupes

    Small Command Line utility written in Python to find duplicate files.

  • My technical blog (Other amazing things)
    http://blog2samus.tumblr.com/

    My personal blog, in which I discuss various programming-related topics and code.

  • Practical Concurrency & Parallelism - PyCON FI 2014 (Other amazing things)
