我的简历

PROFILE

A student building GPU kernels, fine-tuned language models, and full-stack applications with real users. Nine Triton kernels benchmarked against PyTorch over nine consecutive weeks, each published with its numbers; a fine-tuned Qwen3-14B serving in production behind vLLM, leading the provider chain and answering faster than the model it replaced.

EDUCATION

Year 11, Auckland, New Zealand. Expected graduation 2028

Relevant coursework: IB Math AA HL, NCEA level 2 (planning for AP calculus & cs exams next year)

TECHNICAL SKILLS

GPU & ML: Triton, PyTorch, Python, GPU benchmarking and profiling, LoRA fine-tuning, vLLM, Modal, eval harnesses

Full-stack: TypeScript, Node.js, Express, Next.js, React, Supabase/Postgres, Web Audio API, Stripe

Practice: Git, GitHub Actions, Playwright end-to-end testing, web security hardening (CSP, XSS)

GPU SYSTEMS & OPTIMIZATION

One Triton kernel per week, benchmarked against PyTorch.

• Cut fused cross-entropy to 15.90 ms against PyTorch's 24.03 ms at vocab 131,072 (1.51x), at 1.67x less peak memory, by collapsing five live copies of the logits tensor to three.
• Raised fused softmax from ~55 GB/s to ~230 GB/s, and established T4's ~240 GB/s practical ceiling by measurement.

DISTRIBUTED AI INFRASTRUCTURE & DISPATCH

• Fine-tuned Qwen3-14B with LoRA on a 1,526-row corpus spanning five generation paths in six languages; achieving full performance for $1.30 of compute.
• Deployed optimized cold-start vLLM architecture, leading the production chain at 2.3–4.1s against the original 5.7s model.
• Built warm-gate routing: the gateway probes for a warm container and the probe doubles as the warm-up, so a 108 s cold start never reaches a user.
• Fine-tuned MusicGen-small for bar-locked stems, built the eval harness scoring clips as production.
