Worked on iOS, and backend. I created a peer-to-peer library for iOS, enabling devices to communicate reliably over LAN to ensure connectivity in the presence of internet outages.
On the backend I created a data pipeline from MongoDB to Elasticsearch to enable reporting features.
Created infrastructure tools such as deployment mechanishm in AWS.
Reworked the authorization mechanism of a Rails app to a standard RBAC model.

Freelancer

Lead the efforts of creating a new backend and designed new REST and GraphQL APIs. Using Scala, microservices, Kafka, ZooKeeper, this new backend powered the contributor platform, mobile apps and web and it was crucial for Pixable’s data efforts involving analytics and machine learning.

Lead Platform Engineer

Lead a distributed team of 5 people shaping Pixable’s mobile experience and reporting directly to the CTO. Transitioned the team to practices including unit testing, code reviews and continuous delivery making the app and the team much more reliable. Coaching the entire team, managing the workload and working hand by hand with product and designers to make the Pixable iOS team the flagship of the company.

Lead iOS Engineer

Full-stack engineer and team lead. I was involved in both iOS development for the native iPad app that acts as the cash register and Ruby on Rails for the backend (web reports and API). I was also involved in front-end development with Coffeescript and Backbone.js. I designed and implemented the REST API that registers use to communicate with the server.
As the first full-time developer of the company I had the opportunity to contribute in key aspects of the development process and in the culture of the team: I established good practices like TDD, pair programming, code reviews and continuous integration in the team and raised the quality of our code making it more maintainable and flexible. I also lead the team through a transition to agile. I designed and implemented several internal libraries like a persistent queue for multithreaded background job execution in Objective-C and an SQL-based ActiveRecord versioning extension. I successfully integrated with partners and third-party APIs like Braintree, Paypal, LevelUp, TGate and Mercury. I integrated hardware with the iPad app like credit card swipers, barcode scanners or receipt printers.
I also collaborated with higher management hiring engineers and shaping the team.

Software Engineer

Built several backends in Ruby on Rails backed by various database technologies including Postgres, MySQL, MongoDB and Redis as a cache.
Refactored many Ruby on Rails legacy projects and added test coverage and set up continuous integration.

Created and maintained several iPhone and iPad apps and published them to the App Store. I've lead teams of iOS developers. 
I have created various open source projects, Nocilla being the most popular with 1800 stars. I've been invited to speak at many international conferences like UIKonf, NSSpain or AltConf to name a few.

Created a backend in Scala following a microservices architecture. The expect throughput of the system was high (high volume analytics) but the team was small (four people). The project was carefully split in small services (separate interfaces and databases) to allow us to independently scale up parts of the system when necessary, but this services were bundled together and managed as a single application to reduce the operational complexity as much as possible.

The purpose of this backend was to encapsulate and old custom PHP backend and a Wordpress instance. Clients apps where consuming from these two backends and it was unmanageable for client developers. This new Scala backend encapsulated them both and served as a foundation for new functionality. 

Communication from the new backend to the old ones was done explicitly, since the new backend sat at the edge of the system as served as an API gateway. Communication in the opposite direction was done via Kafka to avoid coupling the old backends with the new one.
