Who I Am

SC
Singapore

I'm an AI/ML Engineer who ships production AI systems end to end. Most recently I designed and built a multilingual HR AI assistant single-handedly — a governed RAG pipeline with citation-bound answers and guards against invented figures, wired into enterprise messaging, an HRIS and Google Workspace, with an operations console so non-engineers can manage knowledge quality themselves.

My background spans AI/ML engineering (RAG and LLM applications, OT anomaly detection, GenAI localization, content automation) and computer science fundamentals (real-time systems, game engines, C/C++) — a rare combo that lets me build things that are both technically rigorous and actually ship. Whether it's a multi-channel YouTube engine cranking out 5+ videos a day or a cloud-deployed LLM workflow, I care about making AI work in production.

Right now I'm at OlaParty/Qoretex, owning an HR AI assistant as both product manager and sole engineer — retrieval architecture, FastAPI services, a Next.js operations console, Dockerised deployment, and the testing and observability to keep it honest. My AI video pipeline work — multi-channel generation with Claude, Gemini, Kling and Veo — is currently paused.

Where I've Worked

OlaParty / Qoretex
AI Product Manager Trainee
Jun 2026 – Present · Singapore
  • Sole architect and engineer of a production multilingual HR AI assistant, owning product scope, architecture and implementation
  • Built a governed RAG pipeline (FastAPI, Python, DeepSeek, BGE-M3 embeddings, hybrid retrieval) with citation-bound answers and a grounding guard against invented figures
  • Integrated enterprise messaging, the company HRIS and Google Workspace for automated knowledge-base sync
  • Shipped a Next.js operations console for answer comparison, analytics and policy-coverage tracking, putting knowledge quality in HR's hands
  • Owned Dockerised deployment, automated testing and per-turn observability across the stack
  • Improved team Dify workflows for livestreamer tooling, including copyright and sensitive-content detection
  • Led the build-vs-buy evaluation of RAG platforms and drove the migration onto Onyx — trading a bespoke pipeline for a maintained one as the codebase grew
Lifegame
AI Engineer
Dec 2025 – Feb 2026 · Singapore
  • Built AI-driven localization workflows for short-form film and video content using Google Cloud infrastructure
  • Engineered deployment pipelines and Cloud Workflows for automated video dubbing and localization
  • Developed translation adaptation, script preparation, and prompt refinement for multi-language dubbing
  • Created avatar-based ad generation pipelines and AI-assisted script creation from app store content
  • Maintained GitLab version control; refined prompting strategies for localization accuracy and tone consistency

Machine Learning Engineer
May 2025 – Dec 2025 · Singapore
  • Sole ML Engineer — designed and delivered end-to-end ML pipeline for OT network anomaly detection
  • Automated ingestion of OpenSearch telemetry → structured time-series datasets for traffic, protocol, and comms patterns
  • Implemented preprocessing and feature-engineering layers to maximize anomaly signal quality
  • Built Streamlit dashboards for anomaly investigation and real-time system-health visibility
  • Integrated LLMs to generate analyst-ready natural language anomaly summaries
Yanmar Singapore
Data Analyst Intern
Sep 2024 – Mar 2025 · Singapore
  • Built time-series forecasting models for product sales and service demand
  • Cleaned, merged, and analyzed multi-source business datasets independently
  • Delivered end-to-end analytics project with actionable business insights

What I've Built

Production AI systems, GenAI workflows, and AI-automated video pipelines. My current build is the HR AI assistant at OlaParty/Qoretex; the video pipeline work below is paused.

🌍
GenAI Localization & Dubbing

AI workflows for translation adaptation, dubbing, and short-form film/video localization at Lifegame. Built avatar-based ad generation pipelines and AI-assisted script creation from app store content using GCP Cloud Workflows.
