Filipe Giusti
I ship software to augment persons abilities and interactions and I also help others do the same.
My expertise is in backend development in different language paradigms, with a bit of frontend and
linux system administration all using my computer science background.
I've been working mainly with Ruby for the last 8 years for companies like Digital Artists, Planbox,
We Heart It and LivePress.
You can find some of my code in GitHub and a little bit more about my technical opinions in my
Stack Overflow profile.

Apr 2016 → Jul 2016
In this project I was working solo and I had to wear many hats. From front end development to system administrator.
Some tasks that I did to bring the project live included deployment scripts for Docker/Kubernetes on Google Cloud Platform
and it's configuration, CI setup, styling and lint checkers, Docker compose for local development and papertrail on docker.
Most of the work was to translate business workflows to code, in a fast to use responsive design. I developed both in Ruby as
in HTML/CSS/JS and as we had many kinds of users with different roles, I developed an authorization layer and different UXs
for each one.
Also we had integrations with Google geocode service, Filestack and Quickbooks.
Consultant – Digital Artists Entertainment

Aug 2014 → Jan 2016
On the Ignition project for Digital Artists I was part of a remote 4-person team and our goal was to build a mobile and a web
application for use by entertainers and their management teams.
I was in charge of the API to support the clients, an administration application for the Digital Artists Staff, the web client and a
marketplace application for publishers.
Ruby was the main language used, with a few different frameworks and a lot of custom code. Ember.js + coffeescript were
also used for the web client.
This suite of applications had a lot of communications with external services like Twilio, Facebook, Twitter, Pusher, ZeroPush,
PriceGrabber, PublishThis and Bitly.
Developer – Planbox

Jul 2013 → Aug 2014
I worked remotely doing full-stack web development on www.planbox.com. I spent my days switching between PHP, Rails,
Backbone.js and puppet.
From the start to end of my time on Planbox our monthly revenue grew by 37% and we had both new users and old users
increasing their plans growing steadily.
One of the goals was to make the application more robust by sticking only to Ruby and removing PHP. I was responsible for
deleting thousands of lines of code and only writing a tenth to do the same job.
I helped revamp the whole application frontend to better reflect the agile entities promoted by Planbox.
Besides multiple features, as part of this project I had to migrate all user files from localhost to S3, for reliability, with zero
downtime.
Also improved the infrastructure by making all servers rely on puppet, configuring an haproxy load balancer with automatic
failover, adding nagios monitoring and mysql manual failover.
At some point I even had to help with customer service.
