Acerca de

I am an Engineering Manager with a strong background in software engineering, specializing in distributed backend systems. I have extensive experience in leading teams to develop, scale, and maintain high-performance, highly available backend systems for both web and mobile applications.

In my leadership roles, I have successfully managed teams of 8-10 engineers, fostering collaboration across cross-functional departments including product, business, and sales. I work closely with my team to ensure alignment on project priorities, career growth, and personal development. By mentoring engineers, I focus on cultivating a culture of continuous learning, sharing knowledge, and implementing best practices.

As a technical leader, I make key architectural decisions, ensuring robust and scalable solutions that meet business requirements. I am ionate about driving innovation while maintaining system reliability and performance at scale. I'm always eager to stay ahead of emerging technologies, patterns, and methodologies to push the boundaries of what’s possible in backend engineering.

  • Design by Contract in Elixir: "Let it crash" meets "It shouldn't crash"

    http://www.erlang-factory.com/berlin2015

    Mission-critical systems cannot afford software crashes due to un-handled runtime errors. In 1996, a $500 million software error caused the crash in the maiden flight of the European Ariane 5 launcher. Media reports indicated that a half-billion dollars was lost. Typically unit tests are used to that the software works correctly under certain example cases but hardly can be used to detect all possible edge cases during development. In contrast, Design by contract (DbC) is a software…

    Mission-critical systems cannot afford software crashes due to un-handled runtime errors. In 1996, a $500 million software error caused the crash in the maiden flight of the European Ariane 5 launcher. Media reports indicated that a half-billion dollars was lost. Typically unit tests are used to that the software works correctly under certain example cases but hardly can be used to detect all possible edge cases during development. In contrast, Design by contract (DbC) is a software correctness methodology that document and programmatically assert the change in state caused by a piece of a program. Contracts, as in daily life, are a set of specifications that cover mutual obligations, benefits and consistency constrains that a software system has to meet. In this talk we will present Design by contract as an alternative approach to ensure correctness of programs in Elixir and give an overview and examples of the properties that can be verified using DbC with the elixir-contracts library.
