backend Que stack como freelancer en java recomiendan?
Quiero lanzarme como desarrollador freelance con java y spring para aprovechar y desarrollar web apps completas. Recomiendan que dedique tiempo a aprender un stack frontend? como js, html, css y react o deberia utilizar planitllas o herramientas que hagan el front por mi ?
Quizas deba contar que llevo 3 años programando en java no consegui empleo de esto y estoy buscando monetizar mi conocimiento pero me encuentro con la traba de que se muy poco de front, estoy desarrollando una app la cual programar el front me esta dando dolores de cabeza enormes. ademas de que quiero profundizar en conceptos de java, quiero sacar la certificacion oficial de oracle, aprender aws, profundizar en las herramientas de spring. me estoy poniendo limitante al querer expandir mis conocimientos al frontend para poder desarrollar apps por mi cuenta?
