Cooler MasterCurrent

AI Engineer

Singapore | Jul 2026 - Present

Build the company's on-prem LLM systems end to end, as the sole engineer on most of them: data ingestion, retrieval, evaluation, GPU serving and deployment. Own 5 production systems and 2 HR pilots four and a half months in, and screened 37 AI proposals from 13 departments.

• Lab report Q&A

  Text-to-SQL and hybrid RAG over 3,500+ lab reports, every number cited to its source cell. The lab has asked 470 questions in 15 weeks.

• Evaluation that gates releases

  Replayed 69 real user questions and fixed the 23 bad answers; every change passes a 264-case gold set. A 7B tied 32B and 72B at 86-87%, so it shipped at 3x lower latency.

• GPU inference

  Served LLM, VLM and streaming speech models with vLLM on an NVIDIA DGX B200. Rebuilt live captions on Qwen3-ASR, term accuracy 58% to 86%, and moved 4 apps to a new model gateway in 4 days.

• Silent failures, caught

  Found a vision model misreading tables without warning and made two reads agree before a value is stored, then corrected 46 stored tables. Caught context overflows on the new model gateway that were silently switching JSON mode off.

AdvancedGRC

Software Engineer Intern (AI/ML Systems)

New York City | May 2025 - Apr 2026

Built Osmos solo during a 12-month placement: a self-hostable RAG platform for PDF-heavy support documents, covering ingestion, retrieval, reranking, evaluation and the product surfaces on a FastAPI backend.

• Support tickets down 36%

  Shipped the RAG platform (FastAPI, Chroma, E5, vLLM) for daily internal support work.

• Judged pass rate 67% to 98%

  Added a Hugging Face cross-encoder reranker and answer/abstain gating, so the system declines instead of guessing.

• Benchmarks, not demos

  Warm latency, ingest throughput, concurrency and retrieval ablations; 132 ms p50 warm latency.

• Research time cut 60-70%

  Automated extraction across all 50 US state insurance regulator sites in Python.

DigiPen Institute of Technology Singapore

Teaching Assistant

Singapore | Aug 2023 - Dec 2024

Supported 8 computer science and math modules with more than 200 students: led labs, debugging sessions and office hours, and graded against clear, consistent standards.

DT Asia Pte Ltd

Software Engineer

Singapore | Jul 2019 - Jul 2020

Promoted from intern. Built Syslog-ng log pipelines into Azure and AWS CloudWatch, saving $50K+ a year, hardened SSH remote-access infrastructure handling 100K+ sessions a month, and ran live product demos for customers.
