Applied AI Engineer in Singapore
I am an Applied AI Engineer based in Singapore. I turn LLMs into reliable production software: agents that take actions, RAG pipelines over proprietary data, and the evaluation and security layers around them.
What I build
- Vertex Labs: an internal platform for deal sourcing and portfolio management used by investment teams across the SEA and India fund.
- VAL: an MCP server exposing an internal API so LLM agents can create and enrich CRM records, with redesigned tool schemas and prompt-injection filtering on write actions.
- Agentic workflows and RAG in Python and TypeScript over proprietary deal, people and portfolio data.
- Investment thesis agent: a LangGraph agent that writes stock theses, tracks whether they prove right and compares models head to head.
- DealFlow AI: an LLM tool that extracts and scores startup pitch decks.
