About Shantanu Kumar

I don’t believe in SEO tricks. I focus on clean code, strong architecture, and data-backed performance.Most websites don’t fail because of content; they fail because of technical debt. I work on fixing that gap. With 2+ years of experience across development and search, I make sure websites are both high-performing and properly understood by search engines.My work is centered on 3 areas:1. Search Architecture: I improve crawl efficiency and solve indexing issues, especially in JavaScript-heavy setups like Next.js and React.2. Performance Engineering: I fix Core Web Vitals (LCP, CLS) through code-level changes, not shortcuts or plugins.3. Structured Data: I implement advanced JSON-LD to help search engines treat websites as strong, reliable entities.I approach every website as a system to debug and improve. By reducing friction between the server and search engines, I help turn websites into assets that actually bring visibility and results.Contact: 9••••••••@gmail.com
