Hi! My name is Estefania 

About Me

Hola! Welcome to my portfolio! I am a passionate career changer, transitioning from the dynamic field of languages and translation into the exciting world of frontend development. With a strong foundation in communication and a keen eye for detail, I bring a unique perspective to web development. My journey from translating ideas into words to translating code into interactive experiences has equipped me with a diverse skill set and a commitment to delivering high-quality, user-friendly web applications.

What I'm up to right now

  • Becoming FullStack by following Helsinki university's Fullstack Open course
  • Adding Claude AI to my toolbox by building a music streaming project. Focusing on integrating the AI with purpose (not vibe coding).
  • Become proficient in React Native by pair programming this app
  • Building a site for a Danish NGO

I believe that design is about more than just making things look pretty – it's about solving problems and creating intuitive, enjoyable experiences for users.

Whether I'm working on a website, mobile app, or other digital product, I bring my commitment to design excellence and user-centered thinking to every project I work on. Explore my work and join me on this thrilling adventure!

  • Professional background

    | Bachelor of Arts in Literature and Languages, Master’s Degree in Creative and Technical Translation

    With a foundation in literature and languages (BA) and a Master’s degree in Translation, I bring a strong academic and cultural perspective to my professional work. I have worked extensively as a translator and as a Spanish language teacher, both in person and online, supporting learners from highly diverse backgrounds and age groups. My teaching emphasizes clarity, cultural context, and adaptability, enabling students to succeed in a variety of learning environments. In addition to teaching and translation, I am also an author of graded fiction readers designed for language learners. These works are currently being used by teachers worldwide, including at universities, as engaging educational materials that combine authentic storytelling with pedagogical value. This blend of academic training, practical teaching, professional translation, and published writing reflects my commitment to language as both a tool of communication and a medium of cultural connection.
