    Who I Am

    Hi, I’m a passionate GIS specialist, data scientist, and full-stack developer with over 5 years of experience turning complex data into insightful visualizations, intuitive web applications, and scalable solutions.

    My work lies at the intersection of geospatial technology, big data, and cloud computing. I specialize in using open-source tools and APIs to address real-world social and environmental challenges. One of my key projects involved developing a nationwide, cross-data dashboard for tracking and analyzing U.S. social patterns through ACS and mobility data.

    I’m proficient in spatial analytics using ArcGIS Pro and ArcGIS Dashboards. My programming toolkit spans Python, R, and for data science and visualization, and Java for back-end development. I’m also experienced in working with SQL-based databases (MySQL, PostgreSQL, DuckDB), and I have hands-on experience with front-end technologies including HTML, CSS, JavaScript.

    Currently, I’m deeply interested in the real-world applications of large language models (LLMs) and multi-modal AI (MCPs). I enjoy staying up to date with new technologies and am always exploring how to integrate them into practical solutions.

    When I’m not coding, you’ll likely find me hiking, exploring new places, or experimenting in the kitchen.
