Sahil Katoch

I am a Full Stack Developer with nearly four years building web and mobile applications that scale and perform. I focus on clean code, sound architecture, and delivering features that meet product goals.

My work spans React, Next.js, React Native, Node.js, Express, MySQL and MongoDB, and I have built RESTful APIs, role-based authentication with JWT, and responsive user interfaces. I routinely optimize performance by reducing unnecessary re-renders, implementing lazy loading, and improving Core Web Vitals.

I collaborate closely with designers, product leads, and backend teams using Agile practices, contribute to code reviews, and troubleshoot production issues to keep systems reliable. I have delivered high-traffic event booking platforms and cross-platform mobile apps with reusable components and efficient state management using Redux/Redux Toolkit.

I hold certifications in Responsive Web Design (freeCodeCamp) and MERN Stack (Board Infinity), and I am continuously learning modern web technologies and cloud basics (AWS EC2, S3) to improve delivery and scalability.
