About

I'm Sahil, a full-stack web developer specializing in secure, scalable applications. Proficient in React, Tailwind, JavaScript, Node.js, Express, and MongoDB, I implement JWT-based authentication and follow OWASP best practices to protect user data. I build generative AI chatbots leveraging Gemini API for context-aware interactions and integrate them into MERN-stack projects for rich user experiences. I prioritize cybersecurity, conducting thorough code audits and employing encryption techniques to safeguard applications against threats, and performance optimization overall. My work blends intuitive front-end design with robust, maintainable back-end architecture, ensuring high performance, reliability, and security.
