Aitana V.
AI Engineer | NLP Specialist, LLM, Deep Learning, Python, ML
I help companies turn data and language into intelligent systems using Machine Learning, Deep Learning, and Natural Language Processing (NLP). I hold a Master’s degree in Natural Language Processing and specialize in building and improving models that understand human language. My work focuses on deep learning architectures, language models, and data-driven AI systems for real-world applications. I also bring a research background, having published peer-reviewed papers in NLP and biomedical language models. This experience allows me to approach problems with both scientific rigor and practical engineering skills, ensuring solutions that are robust, scalable, and well-validated. What I can help you with • Natural Language Processing (NLP) solutions • Machine Learning and Deep Learning model development • Large Language Models (LLMs) and transformer-based systems • Text classification, entity recognition, and information extraction • Data analysis and exploratory data analysis (EDA) • Model evaluation, optimization, and experimentation • Data preprocessing and feature engineering • Python-based ML pipelines Research & Publications • Improving Medical Entity Recognition in Spanish by means of Biomedical Language Models — MDPI Electronics (2023) • Generation of Synthetic Sign Language Sentences — IberSPEECH 2021 Education & Specialized Training • Master’s Degree in Natural Language Processing • DeepLearning.AI – Natural Language Processing Specialization • IBM (Coursera) – Exploratory Data Analysis Tools & Technologies Python • PyTorch • TensorFlow • NLP pipelines • Machine Learning • Deep Learning • Data Analysis • Language Models • Text Mining • Neural Networks I’m particularly interested in projects involving NLP, deep learning, language models, and AI research applied to real-world problems. If you’re looking for someone who combinesresearch expertise with practical machine learning development, feel free to reach out. I’d be happy to discuss your project.
