ABOUT

Profile Picture

I was born in 2004, and spent most of my childhood in Raleigh, North Carolina. I presently live a few hours away in Boone, and study Computer Science and Mathematics at Appalachian State University.

I generally enjoy applying pattern recognition and optimization across many domains. I specifically enjoy competitive programming and algorithmic puzzles, cooking, swimming, and running. I'm currently extending this site with a page about books I'm reading.

I love to nerd out about programming languages (ask me my favorite C++ Standard), new tools, and retro tech. I sometimes write about interesting things on my blog.

I am graduating in the Spring of 2026 and am looking toward numeric horizons. Please feel free to contact me for any opportunities!

EXPERIENCE


☁️ NetApp

Software Engineering Intern
ONTAP (storage OS) Team: Shipped the OKM Toolkit, a cluster-passphrase recovery utility for encrypted ONTAP systems, now used by customer support. Implemented cluster-wide password handling, AES-based encryption, OpenSSL primitives, and TPM/key-file recovery. Lots of C++ and free snacks!


🌲 Appalachian State University

Teaching Assistant
CS 3481 - Computer Systems: Gave talks on GDB, Valgrind, C & C++ Programming, Architecture, and Assembly. Held regular office hours, led Lab sections, and reviewed/graded student programming assignments. Spawned a love for low-level systems programming.

Research Assistant
Maths Department: Translating recent papers into Python models then testing and visualizing the results. A short-lived experience but a lot of fun, and my introduction to academia.

Private Tutor
Operated an independent tutoring venture for collegiate-level Calculus, Statistics, Linear Algebra, and Discrete Mathematics. Classic College-kid hustle.

SELECTED PROJECTS


Interactive GPU Fluid Sandbox
(C++, CUDA, 2025) Paper
Real-time GPU fluid simulation running 16.7M cells (4096²) at 176+ FPS. Implemented CUDA kernels for advection, diffusion, and Poisson pressure projection; optimized shared memory tiling & coalesced access. Improvement over my previous OpenMP CPU version.


Lock-Free MPMC Telemetry Buffer
(C++, 2025) Repo
High-throughput lock-free queue for telemetry objects from many threads concurrently. Designed as a bounded ring using C++ atomics & cache-line padding to mitigate contention and false sharing. Sustains ~20M events/s on 4 cores and outperforms std::mutex by ~9x in some cases.


IN PROGRESS


C to LLVM Compiler
(C++)
Writing a C-subset compiler with custom loop-invariant code motion and strength reduction.


Micro-Firewall DSL
(C, C++)
Inventing a small Domain-Specific Language (DSL) compiling to eBPF bytecode for programmable packet filtering. Currently learning the network stack!

CAPABILITIES


Languages:
(primary) C++, C, Python, (learning) Rust, Bash, (most types of) Assembly. Adaptable to new languages quickly! Concurrency & GPU:
CUDA, OpenMP, MPI, SIMD (coming to C++26 soon!!), lock-free. Tooling:
Linux, CMake, Git, Docker, gdb, perf, cachegrind, callgrind, valgrind (all the grinds...), Nsight Compute/Systems, (learning) eBPF. Domain:
I'm extremely interested in working with high-performance systems, concurrency, runtimes, operating systems, and infrastructure!
