I primarily use Python for backend, scientific, and general-purpose work, and use React/Typescript for building web apps.
For deployment, I am happy with both GCP and AWS. For hosting, I use GitHub Pages for open source projects.
I'm currently going through the CMU Intro to Database Systems course, learning more about database systems and following the coursework in Rust. Following this I will be going through the advanced course as well as starting fresh on the long path of building out a system designed for production use.
