My Career

I’ve got a bachelors degree in Computer Systems Engineering specialized in “Distributed Systems” and I’ve been working as a Software Engineer since 2009. My experience has been focused in large Java systems as Web and Enterprise applications, and most of my time I’ve been working as a back-end developer by doing tickets, designing and implementing new features, scaling up, upgrading to new versions, applying security, communicating systems, refactorizing code to improve performance, handling concurrency in distributed envs, and improving the collaborative company’s culture by sharing knowledge for cross teams.
