Hello everyone! I have over 12 years of experience in software development, adept at tackling both backend and frontend challenges using Angular, NodeJS, and Flutter as my main tools. I also have many years of experience in UI and UX design ensuring seamless and engaging digital solutions. I’ve had the opportunity of working on local and international projects on the private and public sector. On those, I’ve contributed as a member with an insatiable curiosity for learning and adopting the industry’s best practices. I want to keep learning how other parts of the world create technology and how tech is expanding the boundaries of what we know and how will it change in the future. When I’m not at the computer, I’m exploring some fantastic world on Final Fantasy XIV, keeping in touch with the artist in me through the piano, or drinking a freshly brewed coffee with my cat on my lap.
