I’m Natalia, an English–Spanish Translator, Reviewer, and Interpreter, and the founder of Nati Castelli Translations. Originally from Argentina and now based in Barcelona, I bring over a decade of experience helping clients communicate seamlessly across languages.
For 10 years, I worked as an in-house translator at a leading Argentinian translation agency, where I honed my linguistic skills, collaborated closely with a team of professionals, and developed a strong eye for accuracy and nuance. Today, I combine that expertise with the flexibility and dedication of running my own business, supporting clients with clear, culturally adapted, and reliable translations.
