I recently graduated from Champlain College with a B.S. in Computer Science and minor in Cybersecurity. Over the past few years I've built strong full stack software development skills, using languages like Python, Typescript, C++, and Rust. I am experienced working in agile software development teams, implementing continuous integration/continuous delivery pipelines, modern cloud-based architecture and remote development teams. I love solving complex problems with code, no matter the domain.
