Hello dear ,

You no need to worry about that . You need to start learning coding from BTECH . It is not that much hard as you think . Even if the student who has no idea about coding before 12th can also become a sucessfull software engineer.It's never too late to start learning programming, and you shouldn't feel discouraged by the average age of software developers nowadays. Software development is all about knowledge and if you are qualified for a job, then age won't be an issue.

Good luck !!
