I build website/web applications using Next.js with typescript most of the time, I use the Context API/Redux for state management depending on the need, I use react-query for data fetching, I have used a lot of styling solutions vanilla CSS, sass, CSS-in-JS (styled-components) but my favorite is tailwindcss.
I'm not a back-end guru but I know how to build servers/APIs when I need to, I build RESTfull/GraphQL APIs using Expressjs.
Prisma is the ORM of choice for me, I use MongoDB with Mongoose for some projects, I know the basics of SQL (PostgreSQL)
I use GIT to track my projects, Github to store them, vscode to wright the code, ESLint to write better quality code.
I'm really interested in web3 technologies and I try to learn a lot about the space, I'm also trying to pick some CI/CD stuff to be a well-rounded full-stack developer .
