About me

I'm a software engineer working across mobile, web, desktop, embedded systems, and core computer science domains. I started with Android development and gradually expanded into cross-platform engineering, applied AI/ML, systems programming, and infrastructure work.

I'm especially interested in how software systems are designed, how components interact, and how research ideas translate into reliable, real-world applications. I value clarity, maintainability, and thoughtful engineering over quick fixes.
