About Me

I'm a MarTech Specialist who connects marketing strategy with technology. With a B.S. in Business (Marketing) from George Mason University, Google Analytics & Google Ads certifications, and hands-on experience across CRM, web development, QA, and AI automation, I adapt quickly to whatever a project demands.

I started with customer data analysis and audience segmentation at a publishing company, then taught myself full-stack development — shipping a live KBO analytics platform (Next.js) and a mobile sports app (React Native). Along the way I've designed A/B tests with Qualtrics, managed ad campaigns, automated business processes with Python, and built AI-powered tools that turn hours of manual work into seconds.

What makes me different: I don't just analyze a problem — I build the solution, test it, and ship it. Whether it's a marketing dashboard, a data pipeline, or a mobile app, I bring a versatile, execution-focused approach to every project.
