## What he works on

Embodied AI agents, voice-first agent stacks, and the infrastructure they run on. In practice
that means three overlapping things: perception-and-planning pipelines for robots in simulation
and on real hardware, realtime voice agents (STT → LLM → TTS with interruption handling), and
the GPU/cluster plumbing needed to evaluate any of it at scale.

## Research and engineering

### EBKernel · 上海具脑磐石科技有限公司 (Nov 2025 – Jun 2026)
Embodied Agent Algorithm Intern · embodied-AI / human-computer-interaction research · remote.

- **RynnBrain VLM × OmniGibson evaluation pipeline:** lifted BDDL true success from 0% to 80%
  by removing six classes of privileged information — ground-truth segmentation replaced with
  GSAM open-vocabulary perception, container AABBs with pixel-level snapping, teleportation with
  CuRobo trajectory planning. 60+ seeds across 3 BEHAVIOR-1K tasks, with 28 falsified hypotheses
  documented (the negative results are part of the record, not hidden).
- **Three-machine remote pipeline:** Mac ↔ RTX 4090 ↔ H100 cluster over SSH tunnels and rsync,
  vLLM TP=1.
- **Robot voice interaction:** co-deployed a realtime voice stack on the Lejun (乐聚) humanoid for
  water-fetch, hotel front-desk and reception scenarios, fully localised to domestic providers
  (Alibaba Cloud TTS/STT, Agora 声网 RTC, TEN Framework). Investigated 3C noise suppression and
  microphone directivity at the hardware/software boundary.
- **Multi-cloud GPU infrastructure:** worked across Huawei Cloud and with the infrastructure
  teams at Kuaishou (快手) and DataCanvas · 九章云极 (Alaya NeW Cloud) on GPU container scheduling,
  heterogeneous-compute cluster orchestration (domestic chips mixed with NVIDIA), and
  shared-compute inference pipelines.

### iMean · 椰子宇宙（杭州）科技有限公司 (Sep 2025 – Feb 2026)
Algorithm Intern, sole engineer on the voice agent, Algorithm Department. Onsite in Hangzhou,
then remote. Owned the full Web + iOS voice-agent stack, cross-testing STT (Deepgram,
ElevenLabs, Gemini), TTS (ElevenLabs, ChatGPT TTS) and LLM options against latency and quality.

## Awards

- **National APICTA Awards (Malaysia Digital) 2025** — Tertiary Student Project finalist for
  SynTour, a Vertex AI Gemini fine-tuned Malaysia travel agent (LangChain/LangGraph, n8n).
  Presented to the category judging panel on 21 Oct 2025 (PIKOM).
- **International Deriv AI Hackathon Challenge 2026** — Certificate of Recognition, RM 2,000,
  as team lead for TradeIQ (14–15 Feb 2026): a five-agent LLM pipeline plus a "Trading Twin"
  behavioural simulation. Signed by founder Jean-Yves Sireau and CEO Rakshit Choudhary.
- **International Amazon Nova AI Hackathon 2026** — Bonus Blog Post Prize, USD 200 in AWS
  credits, for NovaTour, a voice-first travel planner on Amazon Nova Sonic/Lite/Act with the
  Strands Agents SDK. Announced 10 Apr 2026 via Devpost.
- **National MariaDB Hackathon MY 2026** — proposal rated A+, finalist, for seamless-rag: a
  MariaDB-native vector + RAG toolkit using VECTOR(N), HNSW and TOON v3 for token-efficient
  retrieval payloads. 23–39% token reduction versus JSON on real datasets (MovieLens, SF
  Restaurant Violations); 538 tests passing.
- **APU Vice-Chancellor's List** — Excellent Academic Achievement, academic year 2024/25,
  signed by Vice Chancellor Prof Dr Ho Chin Kuan.
