I'm a web developer with 15+ years of experience building web applications.
Over the last years, I've specialized in Ruby on Rails, working on fullstack projects with Angular on the frontend.
I’m passionate about clean code, TDD, automation, and CI/CD pipelines.
🇨🇺 Originally from Cuba, now living in Germany 🇩🇪.
📚 Lifelong learner, currently diving into Kubernetes, ViewComponents, and AnyCable.
I bring a strong sense of discipline, loyalty, responsibility, and commitment to every team I join. I strive to contribute with critical thinking while also respecting and supporting the final decisions of project leaders. I believe in long‑term collaboration and being fully accountable for both the code I write and the goals we aim to achieve as a team.
I also make critical and intentional use of AI tools in my daily workflow. I believe AI adds real value when used to improve code quality, reduce the learning curve when tackling new challenges, and speed up experimentation — without losing ownership of the decisions I make as a developer.
