Hi aspirant,
In order to become a successful web developer you must excel in language les like JAVASCRIPT,PHP, .NET, HTML, CSS etc . Also you will learn about some of these programing languages during your BCA course. You can work freelance on any private project to have it in your CV. Also you will acquire some communication skills in your BCA, so looking at all these things you can grab a job of web developer at an IT company. With all this keep your linkedin game up.

Thank you
