Started working around 2018. My fisrt job was at doing an Android app from the bottom. There was nothing designed so I had to take decisions on the architecture on it. It was rough but I have fond memories of that project.
After that I jumped to freelance Backend Development.
I was not alone at this. I started taking full stack jobs with friends, in total we are a team of 3. We have a purely Front End Developer, and two Full Stack Developers, but normally I prefer to take backend tasks only
After being freelancer, my absolutely favorite part is seeing clients getting happy with their products, simple things like "It works as I imagined" brings me too much joy.
I still think that I have a long road to cross, so I improve myself little by little.
There may be some extra libraries that I have used but the ones listed before are the most important
