BrainBoost Lab (VIP) · Georgia Tech

Jan 2025 — May 2025
Undergraduate Researcher · Atlanta, GA
  • Built a Python NLP pipeline parsing student math input into ASTs (operators, operands, identifiers).
  • Built a React + SQL layer letting students define and manipulate symbolic expressions.

New York Edge

Jun 2024 — Aug 2024
Computer Science Instructor · New York, NY
  • Taught modularity, debugging, and version control to 30 high-school students.
  • Ran group coding projects in JavaScript + GitHub modeling the software lifecycle.

Projects

P01

Multithreaded OS Scheduler

Apr — May 2026

A from-scratch scheduler in C coordinating up to 16 concurrent CPU threads through a shared ready queue. Built a thread-safe queue with pthread mutexes and condition variables that blocks idle threads to eliminate busy-waiting, and implemented FIFO and Round-Robin policies with fine-grained locking to prevent deadlock and cut contention.

Hermedoc — Offline RAG System

Nov 2025 — Jan 2026

Secure offline RAG system letting DoD-restricted industries query private data locally via LLaMA-3. Generates embeddings with Hugging Face + LlamaIndex into a local vector database for contextual retrieval, fronted by a React + Flask UI built for non-technical users.

About

I do my best work close to the metal: pipelines, caches, schedulers, and the parts of a system most people are happy to abstract away.

This summer I'm joining AMD to work on CPU systems performance. Before that I interned at Intel on GPU validation, and on campus I TA computer architecture, there's no faster way to actually understand a processor than to explain it to a room that doesn't yet. Outside of class I write a lot of C and C++, build things like multithreaded schedulers and cache simulators, and spend a suspicious amount of time chasing race conditions and shaving off microseconds.

That low-level focus is deliberate. I'm drawn to performance engineering, concurrency, and latency-sensitive systems: the kind of work that defines quant development and HFT, and that carries cleanly into systems-heavy software roles. I'd rather know why something is slow than guess.

When I'm not profiling something, I'm usually on a hiking trail, on a basketball court, or hunting down good food in a new city. Brooklyn-born, which probably explains the impatience and the strong food opinions.
