Fernando Martínez González

Software Engineer

Summary

I am a passionate software engineer with deep experience in Python, from backend systems and data pipelines to cloud infrastructure and DevOps. I thrive in collaborative teams, enjoy tackling challenging problems, and believe that technical excellence is built on strong fundamentals and continuous learning.

I learned to program without internet access in Cuba, which taught me to value fundamentals, resourcefulness, and creative problem-solving. This foundation has shaped my approach to software engineering and set me apart in a world increasingly reliant on AI tooling.

My technical expertise spans Python, JavaScript, TypeScript, Go, C++, C, C#, relational and non-relational databases, Docker, AWS, GCloud, Terraform and other HashiCorp products, Git and CI/CD workflows, plus frontend and backend development. I also enjoy functional programming with languages like Haskell and Clojure, though most of my professional experience has been with imperative paradigms.

I tailor my work and communication to the needs of each team and project, and I am always eager to learn new technologies and adapt to different roles—especially those focused on Python.

Sep 2018–Sep 2020 University of Havana [Havana, Cuba]

Professor

Distributed Systems and Computer Networking Professor.

I had to prepare and evaluate multiple projects and courses. In the realm of distributed systems things like Distributed Hash Tables and Consensus Algorithms were very common and fun to work with. Many of the projects imitated ideas like BitTorrent and MapReduce.
