Need help selecting the correct NOC
 

Hi all,

I'm in the process of applying for the skilled worker PR.
I need some help with selecting the correct correct NOC from the list.
I've been working as a software engineer for the last 3+ years. I have experience with the entire life cycle of the Software development including web development.
When I check the NOC list I find that I can put myself under 2173 (Software Engineers and Designers), 2174 (Computer Programmers and Interactive Media Developers) and 2175(Web Designers and Developers).

I'm confused on what to select from this.

Thanks,
Chamila
