Co-founded Spawn, a social planning app that turns 'we should hang out' into a single tap, now live on the App Store. Built the backend in Java Spring Boot with a MySQL schema behind 40+ endpoints for events, discovery, and social features, and added Redis caching that cut query latency by up to 70%. Set up CI/CD on Railway with isolated dev and prod environments to keep releases from breaking things.

Wrote the real time control system that lets UBC Sailbot's autonomous boat navigate open water on its own. Processed live wind and sensor data through ROS publisher subscriber nodes, tuned the sail angle logic to cut travel time by 15%, and shipped it with 100% pytest coverage across both normal and emergency conditions.

Replicated a 2025 paper that swaps the classical attention blocks in a CNN for variational quantum circuits. Built the architecture in PennyLane and PyTorch, matched the paper's MNIST and Fashion-MNIST baselines, and dug into why the CIFAR-10 numbers diverged, concluding that quantum advantage on today's hardware is very sensitive to optimizer and architecture choices.

Built a simplified UNIX shell in C that starts and manages up to 32 concurrent processes. Wrote signal handlers to forward interrupts like keyboard signals to the right jobs, and handled the concurrency issues that come up when a signal handler modifies shared job state in the middle of a command.

Rebuilt the core of dynamic memory in C, reimplementing malloc, free, and realloc from scratch. Added block coalescing before and after each freed block to fight fragmentation, then hardened it by tracking down over 50 memory bugs and validating everything against a 50+ case test suite.

Streamed audio straight from flash memory to a DAC on an FPGA with no OS in the loop. Built a custom FSM to pull samples over Quad SPI and a 22 kHz timing pipeline that kept memory reads and audio output in sync without underruns.
