About¶
Upstream contributions across the LLM-inference stack span
FlashInfer,
vLLM,
SGLang,
PyTorch,
Dynamo,
NVIDIA
CUTLASS / TensorRT-LLM, and
LMDeploy —
with work on correctness, distributed inference, and serving performance. See the
auto-updating PR wall and Patches.
Production LLM infrastructure for real customer environments, from site constraints and preflight validation to acceptance and handover. Work spans Kubernetes, GPU runtime, networking, storage, certificates, and model-serving endpoints.
Experience taking an enterprise multi-agent platform from PoC to production, with a focus on model serving, performance evaluation, and solution architecture.
Focus¶
Broadly, I care about inference performance you can trust — fast kernels that also compute the right answer. Three threads:
- Serving internals: KV-cache, quantization trade-offs, attention kernels — enough depth to reason about cost and latency at design time.
- Upstream enablement: early consumer-Blackwell (SM120) and NVFP4 support across kernels → engines → disaggregated serving; my favorite prey is the silent-correctness bug — tests green, answers wrong.
- Trustworthy ML: safety alignment against harmful fine-tuning; federated learning, differential privacy, secure multi-party computation.
