Parkscout.io - National Park Mapping Tool and Trip Planner

This ongoing project is intended to be a one-stop shop for all the data and tools needed to plan a trip to a U.S. National Park.

About Me

Software Engineer with ~4 years of experience, primarily backend-focused, utilizing Python, Typescript, and AWS.

My experiences at Capital One have allowed me to design, build, and deploy high-impact products from the ground up, including a real-time marketing decision platform that now handles over 100 million daily records and supports major campaigns. I also played a key role in developing a self-service kiosk for cashier's checks, guiding it through pilot testing and supporting its production deployment across multiple locations.

With a background in both computer science and physics, I bring strong analytical and problem-solving skills to each project, helping me navigate complex challenges across the full development lifecycle. I'm passionate about bringing practical, robust solutions to life.

In my personal time, I love staying up-to-date with new technologies and am currently building a web app focused on outdoor recreation, powered by large language models. If you're interested in connecting, let's chat!
