    I started learning programming languages two years ago. By now I am experienced with HTML, javascript, CSS, Python, Lua, and the frameworks Vue and Node.js. I have a couple of projects and for now, I am working with a couple of people on their project. I am working in the community of FiveM that they want me to fix bugs, errors, remake resources, make resources, and then test if everything is working correctly. A company named MotoFiber contacted me and they asked me if I can make a website with my own design so I said yes. In a couple of weeks, I finished the site for the company and now I am searching for my next time-consuming project.
