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 pursuing a Master's in AI at CamTech while working as an 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.
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).
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-turn conversation history, system prompt configuration, and a glassmorphism floating widget embeddable in any website. Powered by Groq (Qwen3-32b) — natively multilingual. Deployed on HuggingFace Spaces via GitHub Actions CI/CD. RAG pipeline in active development.
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.
