I’m a Staff Engineer and Computer Engineer with 10 years of full experience in the IT industry, with passion for learning cutting-edge technologies.
I’ve participated in more than 12 projects in cross-functional teams between 6 and 12 people, with clients like Paypal, Ancestry, Salesforce, Mercedes Benz, Bancolombia, just to name a few, so I feel comfortable being involved in industries like Software, Health, Finance, Energy.
In my latest projects I met Elixir and I just fell in love with this functional programming language, and how complex problems can be solved in a fancy way, tackling situations like high availability, concurrency and distributed systems.
I really enjoy being able to support and encourage the growth of the Elixir community!

Cracking the PubSub Code: Elixir's Key to Scalable Real-Time Systems
This talk explores the inner workings of PubSub and its crucial role in building scalable, fault-tolerant, and real-time systems.
It begins with an introduction to the Publisher/Subscriber pattern, highlighting how it decouples services and facilitates efficient message broadcasting in distributed architectures.
The session then delves into Phoenix.PubSub, showing how it powers real-time features in LiveView and handles clustering across multiple nodes.
Two hands-on examples will demonstrate PubSub in action: a GenServer broadcasting state across nodes using libCluster, and real-time updates between LiveComponents and LiveView.
Perfect for Elixir developers looking to master PubSub and build resilient, scalable applications.
