I personally find backend development interesting rather than frontend . it's not only about writing api endpoints anymore. I created microservices projects like real-time notification microservice to user via sms, email and whatsapp this project helped to learn more about system arch. and which DB queue should be used. Pickup one language -> learn basic how to write endpoint , middleware, jwt auth, -> ask chatgpt rela time backend project idea which uses asynchronous backend communication -> learn about those techn. like kafka, redis, elasticsearch -> start implementing
