Ricardo uses Ruby, Python, JavaScript, and TypeScript to build scalable and reliable systems that enable product delivery and release, from modern CI/CD pipelines to automation and observability tooling. In addition to his engineering expertise, he has extensive experience in Machine Learning and Data Science, working with TensorFlow and PyTorch and applying classical algorithms like regression and decision trees. With a background in data preprocessing, feature engineering, data mining, and model training, he has hands-on experience with Deep Learning through Computer Vision projects, deploying models into production environments, including integrations via AWS Bedrock, OpenAI API, Grok API, and DeepSeek API. In the LLM space, Ricardo works on fine-tuning and prompt engineering and is familiar with tokens, embeddings, and model architectures. He has built recommendation systems using OpenSearch and AI and brings awareness of AI ethics and bias considerations.
