Some opinions about CodeWorlds

For 16 years, I worked in public administration until I experienced burnout. I tried to learn programming on my own, but I lacked the right resources, knowledge, and professional support - many times, I was on the verge of giving up. Joining CodeWorlds allowed me to grow, acquire new skills, and gain access to modern technologies. After six months, I found a job as a mid-level front-end developer, and shortly after, I switched to working on an international project. I am incredibly grateful for meeting Piotr - I can confidently say that it was one of the turning points in my life!
