Data engineer 3 YOE salary expectations

I have 3 years of experience as Azure data engineer. Have 10 Azure cert, 2 Databricks, 3 GCP, 1 Snowflake, 1 oracle cloud Dropped my papers due to notice period rejection. Have 3 months now to find offer and get the new job. What salary I should ask as per my skillset. I also want to know that should I ask for 50,60% hike first n then ask for counter offer of 100% hike or directly go and ask for 100% hike. Any company suggestion to switch for are also welcomed.
