Spanish AI training and evaluation domain expert specializing in language quality and model testing.
ColombiaWhat I'm looking for
I’m a Spanish AI training and evaluation domain expert building and refining AI-powered language tools. I’ve developed applications using Whisper (speech recognition), MarianMT (neural machine translation), and multiple LLM APIs (Gemini and Groq), then systematically tested Spanish outputs for accuracy, naturalness, and cultural appropriateness.
Beyond engineering, I bring real-time language judgment from my work as a medical interpreter, assessing whether phrasing is accurate, natural, and contextually appropriate under real conditions. That experience strengthens my ability to evaluate AI model performance on Spanish prompts using the same practical standards: clarity, fluency, and fit for the intended context.
I’m detail-oriented and comfortable working independently on focused tasks, with a strong track record in evaluating model output quality. From prompt testing and linguistic analysis to end-to-end projects like a speech-to-speech translation tool and an AI Telegram assistant, I consistently iterate until the language reads correctly for real users.
