Dear Ankita, all the best for your role. If you really have the zest for being a good HR professional, there is no need for any certification. On-the-job training and day-to-day activities will provide you with more knowledge.
Requirements to Define
1. What kind of HR setup does your organization require?
2. What resources are available?
3. Is the management ready for the implementation?
Clarify the above with your management. Then it would be the right time for you to have a perfect start.
Regards,
Satya
