<h2 id="summary">Summary</h2>
<p>I have 8 years of experience with web development. I have worked in
many different layers of software development, including backend,
frontend, mobile and infrastructure. My main focus is backend and I
advocate code quality, readability and maintainability. I include tests
on my daily development practice, along with TDD and refactoring.</p>
<p>My main skill is learning, and I like to stretch it in daily
challenging situations. I was lucky to have had the opportunity to join
my first three jobs without knowledge of the technologies involved and
have learned them. I love environments where I can grow, surrounded by
smart and interesting people.</p>
<p>I love to code, and more specifically, I love programming languages
and paradigms. In my free time, I have experimented with many
programming languages and technologies, including SML, Python, Ruby,
Haskell, Scala, Go, Rust, Racket, Bash, Clojure, etc and even designed
my own language. I’m also confident working with fast delivery,
continuous integration and many agile ideas. I’m fluent in Portuguese
and English and also a game and music enthusiast.</p>

Developer at Babbel</h3>
<p><small>August 2017 - present</small></p>
<p>At Babbel I help build APIs and platform support for mobile and web
clients. A big part of the work is designing good APIs that can be used
by current and future company initiatives. I’m also participating on the
microservice extraction initiative, as well as helping bring the
development, testing, infrastructure and interviewing practices up to
date. We deal with lots of AWS services and automated infrastructure. I
was a major contributor to migration of user’s vocabulary from MySql to
DynamoDB.</p>
<p>I also contribute to Babbel’s engineering strategy, helping teams
become more autonomous and spreading knowledge about content
distribution and overall architecture. My work in this area resulted in
my promotion to Principal.</p>

<p>I joined a team of full-stack developers at Movinga and immediately
started working on a micro service and its three client applications. I
was also responsible for starting a couple of frontend applications from
scratch. Later we extracted a pricing micro service from the main legacy

was responsible for receiving and encoding videos to be prepared for
internet delivery. We worked on a system that provided both an UI and an
API for uploading videos and metadata. This system was distributed in
more than 50 locations across Brazil, gathering and processing videos
from all partners. We processed more than 2.5TB of videos on a weekly
basis, accounting for more than a thousand hours of content.</p>

third party APIs</li>

all parts of the development, so I had the opportunity to work with a Go
backend hosted on Google App Engine, an Android and an IoS application.

<p>Accomplishments:</p>
<ul>

<p>We developed a single page application for a remote client in New
York. I was hired not only because I knew some of the technologies
involved but also because I was willing to learn the ones I didn’t know.

<p><small>July 2012 - February 2013 <em>(8 months)</em></small></p>
<p>We developed systems for startups. It was my first experience with
Rails, but also included frontend development. Since each developer was
responsible for managing a whole project, our responsibilities involved
coding, creating interfaces, thinking about user experience, negotiating
with clients, managing infrastructure and deployment, etc.</p>
<p>I was one of the first people to be hired on our branch of the

industry, with daily client facing situations. I worked mostly on
maintaining and developing new features for a large legacy Java code
