Hello. I build systems that move data, decisions, and people.

I'm a Final-Year student at The Hong Kong Polytechnic University pursuing Computer Science with a minor in Business Management & Economics. I focus on workflows involving middleware and distributed computing, with side-quests into cloud, data analytics, finance, and applied AI.

I've represented AWS since 2022 as Ambassador, Cloud Captain, and Hong Kong Student Community Lead. I learn from people who are better than me, then use that exposure to sharpen how I build.

Five stations.
One trajectory.

06 // RESEARCH SIGNAL

Squeezing more model
into less silicon.

RESEARCH // ONGOING

KV Cache Compression on the GPU

Integrating a new lossy CUDA compressor that reduces the Key-Value cache footprint inside the vLLM library. The goal: enable higher-performing models to run on smaller GPUs with acceptable performance trade-offs — widening the gap between research-grade hardware and consumer-grade access.

KV CACHE / RAW attention.k attention.v SIZE = 100% CUDA COMPRESS LOSSY KERNEL block-wise quantize vLLM RUNTIME KV CACHE / COMPRESSED SIZE ≈ 35%

VISION

Models on smaller GPUs

The democratization layer. Larger models on hardware that already exists, instead of waiting for hardware that doesn't.

METHOD

CUDA-level integration

Compression happens inside the GPU memory pipeline — not as a Python pre-step. Closer to the metal, lower the overhead.

07 // FIELD OPS

Beyond the terminal.

Communities are systems too. Here are three I helped build — with ops manuals, dependencies, and uptime requirements of their own.
