My work mainly revolves around AI, web development, and data driven solutions, with a focus on creating projects that are both useful and easy to use.

I have been involved in various technical and leadership initiatives, ranging from managing student organizations to working on collaborative projects with developers and creatives. Much of my time is spent organizing events and mentoring others to help grow the local tech scene while refining my own skills in software development and data.
