I usually do fullstack (frontend and backend) in TypeScript. My preferred stack in full stack development is the PERN stack (PostgreSQL, Express, React, NodeJS).
Unity with C# is my preferred stack in Game Development. Processing 3 with Java is also an option for smaller game projects. I am capable of writing shaders including compute shaders to optimze certain computationally intensive tasks. See my Itch Page to find my past game projects.
