Eder Ruiz | Curriculum Vitae

I’m passionate about understanding how things work and what fascinates me most is the world of computing. This fascination quickly led me to the world of Linux and Open Source which in those days meant knowing how to use the command line to operate the system.

In terms of programing, I'm folling in love with functional paradigm, actor model, reactive programming, strong type system, and massive data parallel programming, ie: Scala, Akka and Spark

Topics that also interest me are Functional Programming, Reactive Arquitecture, Actor Model, Big Data, High Availability, Fault Tolerance, Event Sourcing, Streaming Processing, CQRS, Operating Systems, Distributed Systems and Cloud Computing.
