Curiosity-driven Data Scientist with hands-on experience in analytics, backend systems, and end-to-end data pipelines. At Datasonic, I contributed to key projects by building Python-based scraping workflows, designing ETL processes with Talend, managing SQL/NoSQL databases, and delivering Tableau dashboards that supported data-driven decisions across teams. I have practical exposure to ML/AI through NLP explorations, human-count detection tasks, and data annotation, and I continuously strengthen these skills through self-learning and applied projects. Known for being a fast learner and strong communicator, I enjoy turning messy data into clear insights and building solutions that are both technically sound and product-focused.
