About
I care deeply about how computers work under the hood and solving operating systems, distributed infrastructure, and the security challenges that emerge at every layer. My strong fundamentals come from a wide arc of experience - an undergraduate degree in computer hardware, two years shipping products E2E as a full-stack engineer, several open-source contributions and an ongoing specialization in core systems. Looking for 2026 new-grad roles where I can build reliable, secure systems at scale. I run Arch btw.
