Hi candidate,

It is good to know that you have an interest in Programming. Also, Java being the difficilt language  that requires good understanding  of concepts and you have dine a certification course in it.

See, doing only certification course will not land you in any job because there are more things to do for getting a job. Prepare for DSA and solve as many questions as possible and after that you can do freelancing.

See, you will face difficulty in getting a job because the basic requirement for any role in software enginerring field requires mathematics in class 12th and you are from pcb background so it will surely create an issue.

Better learn some development skills and start freelancing.

Hope you understand.

Thank You!!
