Freelancer Overview

I’m a Systems Engineer with strong experience in data annotation, AI model validation, virtual assistance, and technical QA testing. I’ve contributed to multiple projects involving image/video labeling, audio transcription, sentiment analysis, content classification, and user interaction review for machine learning training. With a background in web development, process automation, and app testing, I bring both technical accuracy and attention to detail to every task. I’m fluent in Spanish and English (B1), which allows me to handle bilingual projects efficiently. I’m passionate about emerging technologies and responsible AI, and I continuously learn new tools and workflows to enhance project quality. I’m reliable, detail-oriented, and a quick learner—ready to contribute meaningfully to AI systems that impact real-world applications.
