I'm most familiar with the tried and true HTML/CSS/JS combo but I've built sites using a the Django framework and MERN Stack. I'm a big fan of Angular (and React) and I've got experience working with Java, Python, and C# (shout-out to dotnet)
I'm looking to dive deep into Angular in 2020 after getting a taste of it last year!
My biggest project right now is my portfolio. It's a static HTML site but a great CSS refresher.
Hit me up for an opportunity to speak to young womxn (esp young womxn of color) about embracing tech as a career/hobby!
