I or no I?

I've sent out 2 more resumes to
1. Compact Administrative Pte Ltd
2. eBay Inc

I've finished with the resume to Karuppan Chettiar but I just need to determine whether is it Mr. Renuka or Ms. Renuka, and whether is it Karuppan or Karuppian.

Quite cheem, all these name thingy.

After these 3, it will be;
Kinetica Pte Ltd
Patrick Miranda Co (s) Pte Ltd
Philips Electronics Singapore Pte Ltd
ACRA

Good luck to me.
