Satvik Sharma
Front-end Engineer · React Ecosystem · UI Polish Obsessive
Hello, I am Satvik. I work as a frontend engineer building high-performance web applications using React, Next.js, and TypeScript. I focus on solving real production problems, from optimizing rendering performance to designing frontend architectures that scale reliably.
My journey into web development started out of curiosity, but quickly turned into a focus on building systems that handle real users and real constraints. I have worked on platforms serving high traffic, where performance, consistency, and reliability directly impact user experience.
I spend most of my time working on server-side rendering, caching strategies, and efficient data handling. I am also interested in clean UI systems, but always from a performance-first perspective.
