Huawei Edge-Cloud Collaborative Inference Contest: 960/4428 [active participants], top 22%
Wrote a performant cloud inference optimizer for LLM usage based on a prediction-driven heuristic scheduling methodology. A difficulty I tackled in this challenge was learning how to apply queueing theory to systems like this.
Huawei OXC Ports Arrangement Contest: 931/3176 [active participants], top 30%
Wrote an optical switch arrangement (load balancer) methodology based off of a meta-heuristic approach. A difficulty I tackled in this challenge was managing the mandatory items and the nice-to-haves in my heuristic search space.
CIRC and URC: I compete in both CIRC and URC with UBC Rover, the University of British Columbia’s Rover team.
