My expertise includes working with a variety of databases (MySQL, PostgreSQL, MongoDB, Elasticsearch) and implementing robust data pipelines and microservices, which has given me a keen understanding of data structuring, quality control, and annotation processes essential for AI and machine learning projects. I am skilled in managing data integrity and consistency across distributed systems and have experience in domains such as e-commerce, IoT, and SaaS, making me well-equipped to contribute to data labeling and AI training data initiatives.
