HyperparameterTuner's journey

I applied for a tech position about a month ago and had my interviews with HR and the tech team. Both interviews seemed to go well, and I received positive feedback from the recruiter after my tech round. However, it has now been three weeks since my last interview, and I haven't heard back regarding a final decision. I'm starting to feel anxious and uncertain about my standing in the hiring process. I wonder if I'm being considered as a backup candidate while they wait for their first choice to make a decision. Should I reach out to the recruiter again or just move on?
