I also implemented a continuous deployment pipeline that allowed us to release new features and bug fixes to production multiple times a day with zero downtime.

I'm excited about the opportunity to bring my full-stack development skills to Yelp and work on features that directly impact the lives of millions of users and businesses. I'm particularly interested in Yelp's use of machine learning to personalize user experiences and detect fraudulent reviews.

Thank you for considering my application. I would love the chance to discuss how my experience aligns with Yelp's mission and contribute to the company's success.

Sincerely,
[Your Name]
