I'm an experienced software engineer who likes to work in the intersection of large-scale data processing systems, functional programming, and automation.

I've spent the last few years working in the domains of text analytics, large-scale data processing, and container orchestration.

My goal is to tackle complex and interesting problems in challenging, creative, and intellectually stimulating environments with a strong engineering culture.

  • Meleva Campinas, São Paulo, Brazil

    Taxi-sharing service.


    April 2012 - July 2013

    • Developed real-time location-aware mobile web applications using PhoneGap, Backbone.js and jQuery Mobile on the frontend and Sinatra, Node.js, WebSocket and MongoDB on the backend.
    • Got into the Startup Chile program, which financed Meleva for six months with 40.000 USD equity-free seed capital.
    • Constructed algorithms for optimally matching users in coherent sets according to their itinerary data.
    • Planned and executed a marketing campaign that brought in five thousand users in a single state, in one month, before launch.
    • Built an unobtrusive caching adapter for AJAX requests using Local Storage, greatly reducing bandwidth usage, database load and client load times.

Programming Languages

I'm most proficient with Clojure, Rust, Python, JavaScript, C, and Bash.

At work I'm currently writing Rust, Python, and Bash. On my spare time I'm currently working on projects in TypeScript, C#, Rust, and Clojure.

I can and have written code in several other languages, like SQL, Haskell, Emacs Lisp, Ruby, Erlang, PureScript, Prolog, Scala, Perl, MATLAB, R.

On my day to day I generally use Clojure or Rust for anything more than small scripts, which I write in Python or Bash.

werld-server and werld-client-tty

Created a multiplayer roguelike game with a chat system. The backend uses Erlang and a TCP server with which the TTY client, made using C, Ncurses and select(2), communicates with using an ad-hoc binary protocol. The backend also has a web interface for managing player accounts made with webmachine and mnesia.


Created a multiplayer online battle arena (similar to DotA) game using Clojure and Unity. (WIP)
