On this blog, I'm excited to share more about my journey from teaching into programming and technology. This blog's creation was part of a final set of projects for my bootcamp, which I completed in July of 2022. It's written in JavaScript and EJS, and styled with the Bootstrap CSS framework and uses a Mongo Atlas database.";

I'm proficient in HTML, CSS, JavaScript, SQL, Python, and the MERN stack and I'm interested in UX/UI elements as well! I've been writing code since January 2022, and I'm happy to share more with you about what I've learned in that time. I'm a proud member of Girl Develop It, an organization that helps women build the skills necessary to succeed in tech. I believe passionately in helping women and girls in STEM. Prior to my career in web dev, I was a public school educator -- high school English -- and team lead. In addition to web development, I love to read, bake, run, paint, and practice yoga.";
