About

I’m a Full-Stack Software Engineer with 4+ years of experience building scalable enterprise applications using React.js, .NET Core and SQL Server, with additional experience in Node.js. Currently, I contribute to Deloitte-owned internal platforms used across multiple teams, working across both frontend and backend layers — from building responsive user interfaces to developing REST APIs and backend services. My experience includes upgrading React applications (v17 to v19), optimizing API performance (~30% improvement), and implementing secure authentication and authorization flows along with web security practices such as XSS and CSRF protection. I focus on building scalable, maintainable systems and improving performance, reliability, and code quality through strong engineering practices. I’m currently exploring full-stack and backend-focused opportunities in product-driven environments.
