01 - about

Who I Am

I build scalable web applications with a focus on backend architecture, API performance, and production-grade security. Passionate about JavaScript, C++, and the MERN Stack. I enjoy designing systems that are fast, secure, and maintainable at scale - from RESTful APIs to serverless edge workers and event-driven queues.
