Professional Introduction

I am a Data Engineer & Freelancer with expertise in monitoring and optimizing data pipelines and architectures to support data-driven solutions. My experience spans Machine Learning Engineering, Data Science, and Data Analytics, where I have developed and deployed predictive models for NLP, Computer Vision, and multimodal tasks using Python, Scikit-learn, PyTorch, and TensorFlow. I specialize in creating scalable ETL processes, managing data integration, transformation, and storage with big data technologies like Hadoop, as well as database systems such as MySQL and PostgreSQL. Additionally, I have a strong foundation in full-stack web development, including front-end technologies (HTML, CSS, JavaScript) and back-end frameworks (PHP, Laravel, Codeigniter), enabling me to deliver seamless end-to-end solutions that integrate data engineering, analytics, and software development.
