During my tenure, I enhanced the search engine results page (SERP) and the Video service results page, leading to notable increases in user engagement, revenue, and web performance. Additionally, I implemented service disaster alerts that automatically created incidents on client error threshold overcoming, enhancing incident resolution speed, and achieving Tier A reliability with 99.99% availability. During performance reviews, I always received high performance ratings. In the early stages of my career, I gained hands-on experience in developing APIs, including REST and GraphQL.
