Translation | Localization | Language Technology & AI

Where language meets technology.

I’m Marina Rey, a recent Translation graduate who worked with English and German into Spanish throughout my degree. I combine specialized translation and terminology work with hands-on experience in AI evaluation and Python-based terminology tools, and I’m looking for my first role in translation and localization in Germany.

A Translation & Computational Approach to Magic: The Gathering

A glossary-based Python prototype for translating the rules text of the trading card game Magic: The Gathering from English into Spanish.

Read the case study+

The challenge. Game rules depend on official terms, recurring phrases and multi-word expressions. General machine translation can communicate the meaning while missing the game’s established terminology.

My approach. After taking an introductory Python course, I applied what I had learned to my thesis: I analyzed the game’s language, compiled an English–Spanish terminology and phraseology glossary, and coded a prototype translator based on it. Giving glossary entries priority levels, so that longer fixed structures are matched first, helped preserve the game’s set phrasing.

The result. I compared my prototype with the official card translations and with DeepL, Reverso and Google Translate. The prototype kept terminology and fixed phrasing more consistent, while the general engines produced more fluent grammar. A key takeaway for post-editing: the prototype’s grammar errors are easy to spot, whereas a general engine’s terminology errors can hide behind natural-sounding sentences.

What I learned. Bugs like “graveyard” turning into “cementrenio” (the term “enter” was being replaced inside the word) taught me that programming problems in translation are, at heart, textual problems. I had started learning Python from scratch, so carrying the project through to my thesis defense, graded 9.9/10, was a challenge and a path I’m glad I chose.

The GitHub repository also includes the thesis abstract and conclusions in Spanish and English.

Subtitling Flotar

Spanish-to-English translation and subtitles in both languages for a short film about love, acceptance, fear and letting go.

Read the case study+

Flotar, directed by Alexia Corrales Rosalén, explores love, acceptance, fear and, ultimately, letting go.

My contribution. I translated from Spanish into English and worked on subtitles in both languages. I loved being part of the project, and found it a valuable introduction to audiovisual translation.

RAG Chatbot for translators

A retrieval-augmented chatbot project for querying client style guides and terminology while translating.

Read the case study+

The problem. Clients may send long PDF style guides and extensive Excel glossaries. Looking up tone, untranslated items, date formats and preferred terms by hand can slow down translation.

Course context. Final project for the Generative AI for Everyone: Build Real-World Applications with Language Models course at Universidad Carlos III de Madrid (October 2026).

The prototype. A chatbot that uses retrieval-augmented generation (RAG) to find the relevant guidance in a client’s uploaded style guides (PDF) and glossaries (Excel) and answer in context.

Example questions. “How does this client want ‘dashboard’ translated?” or “Does this paragraph follow the client’s style guide?”

Why it matters. It explores how external client documentation can be connected to an LLM to support consistent, context-aware decisions in a translation workflow.

For the 16th ECOshow, my team created an interactive map of places and services that could help people from Slavic communities as they settle into Valencia. I was delighted to take part in a project designed around a real community need.

My contribution. I built the interactive map in Google My Maps, organizing the places into categories such as restaurants, shops and groceries so people could find what they needed at a glance.

Portrait of Marina Rey García

I studied Translation and Interlinguistic Mediation at the University of Valencia, working from German and English into Spanish. My projects have taken me from terminology, text revision and specialized translation to localization and language technology.

Since 2026 I have worked as an AI evaluator and Spanish language expert, reviewing AI-generated content for accuracy, terminology and naturalness. Before that, I spent several years as an English tutor and camp monitor. Across these different settings, I enjoy making language useful in practice—whether that means finding the right wording, helping someone gain confidence, or making information easier to follow.

Let’s make language work across borders.

I’m looking for an Erasmus+ internship in translation, localization and language technology, and I’m available from February 2027. I plan to move to Germany (city still open) and, as an EU citizen, I don’t need a work permit.

I can hold conversations with colleagues in German, which I see as essential for properly understanding their requests. My B2 exam is in February 2027.

Kurz auf DeutschIch suche ab Februar 2027 ein Erasmus+-Praktikum in Übersetzung und Lokalisierung. Ich plane, nach Deutschland zu ziehen; die Stadt steht noch nicht fest. Als EU-Bürgerin brauche ich keine Arbeitserlaubnis. Ich kann mich mit Kolleginnen und Kollegen auf Deutsch unterhalten – das ist mir wichtig, um ihre Aufträge richtig zu verstehen. Meinen Lebenslauf auf Deutsch finden Sie im Abschnitt „CV“.
