I want to integrate genai into my project .I know ml/dl and nlp as im from data engineering background . Can somebody suggest what are all the things i need to focus on to build a genai for my project.

The requirement is very vague. Can you provide some more information on what kind of project you want to work on. Gen AI can be included in many many diverse streams. But how effectively it's utilized is dependent on how well it works within your project context..
