I'm Monireach Tang — AI Engineer building production-grade AI systems in Southeast Asia: semantic search serving 6,000+ users, LLM microservices, RAG pipelines, and containerized deployments. Best Paper Award, ASIP 2025.
Background
Cambodian AI Engineer and graduate researcher building production AI systems in Southeast Asia. Currently Generative AI Specialist at Manulife Cambodia — designing LLM-powered solutions with multi-agent orchestration (LangGraph, Pydantic) and RAG for enterprise-scale deployment. Pursuing a Master's in AI at CamTech. Volunteer AI Engineer at R4C — building systems that serve real users, not demos. Multilingual: Khmer, English, Chinese. I learn by doing: no theory without a working system behind it. I also leverage AI coding agents — Claude Code, Gemini CLI — to ship production systems faster without sacrificing quality or standards.
Master's research: "Contactless AI-Powered Abnormal Movement Detection for Elderly Safety" — Computer Vision, Edge AI, privacy-by-design. Best Paper Award, ASIP 2025 (Privacy Governance in AI-Powered Elderly Monitoring) — published paper ↗.
Semantic search, RAG pipelines, LLM microservices, vector databases (Pinecone, ChromaDB), Docker multi-environment deployments, FastAPI backends, CI/CD with GitHub Actions.
Work
AI-powered platform serving 6,000+ Cambodian teachers — improved resource discovery accuracy from 25% to 58% (132% improvement) via hybrid semantic search combining embeddings and keyword matching (<2s response time). Multi-cloud architecture: OpenAI GPT-4/Gemini for chat and translation, Google Cloud Speech-to-Text for voice input, Pinecone for 1,400+ resources. Bilingual (Khmer-English) with 90% cost reduction via intelligent caching.
Production LLM microservice with multi-tenant SaaS architecture (API key auth,
tenant-scoped data isolation), hierarchical context memory, and RAG-based
domain knowledge layer (ChromaDB). Powered by Groq (Qwen3-32b) — natively
multilingual. Shipped as a <smart-chatbot> web component
(Preact + Shadow DOM) with CSS custom properties theming, deployed on HuggingFace
Spaces via GitHub Actions CI/CD. 78/78 tests passing.
End-to-end ML system covering the full lifecycle from data preprocessing to production API deployment. Achieved 96% precision and 91% F1 score through custom threshold optimization and business cost-aware metrics. REST API with SHAP-based model explanations and real-time predictions.
For Businesses
A smart chatbot trained on your business content — answers customer questions accurately, in your language, 24/7. Embeddable on any website.
Replace keyword search with AI-powered search that understands meaning. Proven impact: 132% accuracy improvement on a 6,000-user production platform.
NLP pipelines built for Southeast Asia — Khmer text understanding, bilingual voice input, and translation. Built and deployed in production, not theory.
