About

I like building things end to end and care most about the details that make software trustworthy. As a UB Forge fellow I'm building Anchor, which routes wheelchair users and blind and low-vision students through campus buildings and refuses to suggest any route it can't back up with data. At Algoverse I set up the GPU environment our research team runs its experiments on.

My coursework leans toward systems. In C I've written a dynamic memory allocator and a semaphore-based producer–consumer queue with POSIX threads, and I'm working through the Pintos kernel in Operating Systems. I also have a long-running interest in data structures, especially hash tables (chaining, cuckoo hashing) and dynamic programming.

Anchor

Accessible indoor navigation for iPhone: step-free routing, spoken landmark guidance, and LiDAR proximity alerts.

My role: Designing step-free routing and spoken landmark guidance in SwiftUI; prototyping the LiDAR proximity alerts.

  • Dijkstra over a directed graph of corridors, doors, ramps, and elevators. Step-free mode excludes every connection not confirmed step-free rather than penalizing it, so stairs can never slip into a route.
  • When nothing qualifies, a relaxed second search names the exact connections that block the trip (“Elevator A (unavailable)”) instead of silently falling back to stairs.
  • LiDAR depth frames are sampled off the main thread at up to 10 Hz, filtered by per-pixel confidence, and reduced to a 5th-percentile nearest distance; the alert policy adds hysteresis, rate limiting, and stale-reading detection.

02 — 3D · Web

Rubik's Cube CFOP Solver

An interactive 3D Rubik's Cube in the browser that solves itself using the CFOP method.

  • Generates interactive 3D solving sequences with a BFS-based move search.
  • Animates face turns in real time with quaternion-driven rotations in Three.js.
  • Migrated a legacy JavaScript/Three.js app to a component-based React architecture, fixing animation-state and rotation-sync bugs along the way.
