About Me
My journey began as a production associate at Applied Medical, where I developed strong organizational and procedural skills. This experience taught me the importance of precision and attention to detail qualities that translate directly to writing clean, maintainable code and following best practices in software development.
My customer service roles at Starbucks and Chipotle taught me to handle pressure and communicate clearly both critical skills for IT support and collaborating on a development team. These experiences, combined with my Computer Science degree, give me a unique perspective on both the technical and human aspects of technology.
I enjoy the entire technology lifecycle, from building a computer from scratch and troubleshooting hardware issues to writing the code for a new application and deploying it to the cloud. Currently preparing for my AWS Certified Cloud Practitioner exam, I'm eager to apply my full-stack development skills in a professional environment.
