What I'm looking for

I seek roles where I can build production RAG/vector search and data pipelines, work collaboratively, learn new tools, and contribute to impactful, data-driven products.

I am an AI engineer and data professional with hands-on experience building Retrieval-Augmented Generation (RAG) systems and maintaining vector databases for production applications.

I have worked across data engineering, data curation, and analysis roles — developing web-crawlers and scrapers with Python (BeautifulSoup, Playwright, Selenium), automating data pipelines using AWS Glue and Spark, and managing vector storage in PineCone.

My experience includes curating and structuring medical and expert datasets for cloud-based systems, developing prediction models and automated daily data-mining systems, and supporting client search applications with RAG and vector search.

I communicate in English, Malay, and Chinese, enjoy cross-industry challenges, and focus on delivering reliable, production-ready data solutions that drive insights and improve application search and retrieval.
