Requesting help in finding whether these job letters are good for my NOC code

[aman.alam]

Hi Members,

Call it my stupidity, but after getting most of my job letters, I found out that the NOC codes have a description too and that the duties/ R&R mentioned in our job reference letters should match 60-80% with that description.

Now I am not sure if my descriptions are okay for the NOC code I want to apply with : 2173 (Software Engineer)

I am putting up the screenshots of my job letters, with the NOC code I am going to use them for, can someone please tell me if the R&R mentioned is good to go for this? Or if any other code should be used?

I have omitted a few private details, and have use personal company codes for nomenclature purposes.

I understand this is not a quick task, but any help will be greatly appreciated

1. Company : CB | NOC Code applied : 2173 (Software Engineer)
   
   
   
   
2. Company : PM | NOC Code applied : 2173 (Software Engineer)
   Note: This company is now defunct, since it was acquired and merged with another company. So I will upload Old Relieving Letter, Offer Letter, Pay Slips along with LOE. Is that good enough for NOC 2173?
   
   
   
   
3. Company : Air | NOC Code applied : 2173 (Software Engineer)
   
   
   
   
   
   
4. Company : HC | NOC Code applied : 2173 (Software Engineer)
   Note: This was a company I co-founded with my friends, ran it as a lead engineer and co-founder for two years, before exiting.
   Does the whole explanation suffice for 2173 or will this be any other NOC code?
   
   
   
   
   
5. Company : HPTK | NOC Code applied : 2173 (Software Engineer)
   
   
   
   
6. Company : TW | NOC Code applied : 2173 (Software Engineer)
   Note and Request: My role here is of part-engineer and part-communicator as a marketer. I build sample apps, proof of concepts, which help developers world-wide, and sometimes some direct customers too. I also go to events and talk about my company's products, and these samples. Thus, I do advocacy. Some also call it Developer Marketing.
   Is this suitable for NOC 2173?
   What other NOC should I apply for this?
   I tried searching but couldn't find anything matching, since the search tool kept suggesting me legal professions for the word advocate.
   Please help
   
   

Thanks so much in advance!!
I'll be grateful
