Designing scalable cloud services and engineering low-level hardware to interface software directly with the physical world.
About
Engineering Philosophy
I am a systems engineer focused on the intersection of hardware constraints and digital infrastructure. My work bridges the gap between low-level embedded architecture and enterprise-scale cloud services.
At Trinity College, I balance a dual major in Electrical & Computer Engineering and Computer Science with the rigorous demands of varsity rowing and a cappella performance. This combination is a deliberate part of my approach to engineering; I find that the most effective software is built by those who understand the physical limitations of the hardware executing it. Whether I am calculating interrupt latency for an 8051 microcontroller or refactoring a data access layer in Spring Boot, my methodology remains consistent: identifying bottlenecks and implementing solutions that balance mathematical logic with physical trade-offs.
My professional experience spans legacy enterprise systems and modern connected infrastructure. At Bullhorn, I managed a major backend framework migration, handling complex namespace changes and upgrading core security dependencies to ensure stability for a global client base. This summer, I’m joining the Cloud team at Sonos to build scalable services that support the next generation of connected audio hardware, working closely with firmware teams to ensure seamless hardware-software integration.
Beyond implementation, my academic research examines the political economy of immersive technology. I analyze how Extended Reality (XR) architectures can bypass cognitive defenses to extract subconscious biometric data, advocating for a structural shift toward a hardware-level "Bodyright" to protect user privacy. Ultimately, my goal is to architect systems that are technically high-performing, physically grounded, and secure by design. Whether in the lab, in a rowing shell, or in a vocal arrangement, I thrive in environments that require precise synchronization across complex, moving parts.

Embodied Harms and Inferred Data: Redefining Privacy in Extended Reality
The emergence of Extended Reality (XR) represents a massive shift in human-computer interaction, transitioning data collection standards from seeking active user input to the passive, continuous collection of "behavioral biometrics." While existing privacy frameworks (such as BIPA and GDPR) focus on identification and secrecy, this paper argues that they are structurally obsolete in an environment defined by inference and manipulation. By deconstructing the "inference gap," the paper reveals how immersive architectures bypass cognitive defenses to extract sensitive psychometric traits, ranging from health status to sexual orientation, without user awareness. Through a comparative analysis of the Apple-Meta dichotomy, the study demonstrates that market-led "privacy-by-design" functions primarily as an anti-competitive moat—a "Walled Garden" paradox in which privacy becomes a luxury good, and domination is centralized rather than eliminated. Furthermore, by applying the legal doctrines of "undue influence" and "defect of consent" to the "Proteus Effect," the article establishes that XR environments possess a unique capacity to vitiate user autonomy through subliminal behavioral modification. Therefore, the paper proposes a pivot from the "notice-and-choice" legal paradigm to a "Bodyright" framework. This rights-based model reclassifies biometric data not as a raw material for extraction but as an inalienable extension of the human sovereign, ensuring that the integration of the metaverse does not necessitate the commodification of human consciousness.
