Trending @Accenture; Career transition advice

Hi...I'm currently in kind of automation+manual testing role..I want to move to some dev roles and i have started DSA in java but need advice on should i focus on spring boot etc or can I focus on data engineering and ml , actually I like data domain but with QA experience both data engineering and especially sde are not possible itseems? I'm having knowledge but tier 3 , should i learn spring boot from scratch or choose data side, but still job market not well, im confused now?
