// About Me

What makes me me ?

I'm a Full Stack Engineer driven by a deep curiosity for how systems work under the hood. My work spans the entire stack—from architecting real-time voice applications, low-latency backends, and AI pipelines to crafting smooth, responsive mobile and web interfaces. I don’t just use tools; I love dissecting them, reverse-engineering APIs, and optimizing low-level performance to build software that scales cleanly and solves real-world problems.

Beyond my core projects, I'm deeply involved in the developer community and open-source ecosystem. Tools and utility libraries I’ve built have reached over a million downloads globally. Whether I’m diving into real-time WebSockets, fine-tuning Linux environments, or pushing code to production, I focus on precision, execution, and creating seamless end-to-end user experiences.
