Freelancer Overview

With a strong background in data science and machine learning, I specialize in AI model training, data labeling, and NLP for diverse applications. I have hands-on experience in annotating and curating high-quality datasets for advanced AI systems, with a particular focus on text generation, language translation, and chatbot development. My work includes building and optimizing predictive models, leveraging machine learning algorithms to uncover insights and drive decision-making across industries like sports analytics, healthcare, and business intelligence. I have a deep understanding of natural language processing techniques, including TF-IDF, word embeddings, and seq2seq models, and I am skilled in bilingual (English/Spanish) data labeling. My expertise extends to working with large datasets, ensuring high accuracy in labeling, and training cutting-edge AI systems. With a solid foundation in Python, SQL, and cloud-based tools like Azure, I am adept at delivering impactful AI-driven solutions that improve model performance and overall business outcomes.

Text Categorization for Multilingual NLP Models

Scale AITextEntity Ner ClassificationTranslation Localization
This project involved labeling a multilingual dataset for the development of an advanced natural language processing (NLP) model. The focus was on annotating English and Spanish text for intent classification, sentiment analysis, and named entity recognition (NER). I performed text categorization and entity labeling tasks, marking key phrases, names, locations, and other entities that were critical for training a language model to understand and generate responses in both languages. Additionally, I was involved in ensuring accurate translations and localizations to support chatbot functionality in both English and Spanish. The dataset consisted of thousands of sentences, ensuring diversity in conversational patterns to enhance the model’s accuracy. Quality measures such as double annotation, verification, and consistency checks were implemented to guarantee high-quality labeled data.

Image Annotation for Sports Analytics AI Models

CVATImageClassificationObject Detection
In this project, I was involved in annotating images for a sports analytics AI model aimed at detecting key player actions and movements during live games. My primary task was to label images with bounding boxes around players, equipment, and significant events like goals, fouls, and other game-related actions. I also worked on action recognition, tagging images with labels such as "dribbling," "shooting," or "passing" to help train a computer vision model to recognize and classify player actions. The dataset included thousands of images taken from various sports, and I ensured accurate annotations through consistent quality checks and cross-validation with fellow annotators. These labeled images were used to enhance the model’s ability to analyze player performance and generate real-time game insights.
