About
I work where product meets engineering: I talk to users, write the PRD, then help build it.
Most recently I planned and shipped an agent-based RAG knowledge platform with hybrid retrieval, 96% answer accuracy and 24/7 self-service. Before that, as a product manager, I found where users dropped off at checkout and lifted payment conversion by about 6%.
Now I'm a graduate student in Systems Analysis at NUS, working as a software engineer at SendOS, and contributing to open-source AI tooling on the side.
Experience
Software Engineer
An AI-native business operating system: chat messages become goals through an understanding pipeline, and every action runs through governed connectors with human approval and an audit trace.
- Platform Development — building the SendOS platform as part of the engineering team.
Full-Stack AI Engineer
- AI Knowledge Base Strategy — planned an agent-based RAG platform giving sales, service engineers and customers AI self-service.
- Product Design — designed retrieval workflows for manuals, FAQs, troubleshooting, citations, feedback and role-based access.
- Retrieval Optimisation — hybrid BM25 + vector search + LLM reranking, reaching 96% accuracy with traceable answers.
- Role-Based AI — role-specific prompt templates and permission models that protect business-sensitive information.
- Delivery — took it from requirements to launch: 24/7 self-service and a lighter support workload.
Product Manager
- Roadmap — user research, competitive analysis and backlog prioritisation with engineering.
- Feature Design — search, favourites, AI input suggestions and toolbar improvements for discovery and engagement.
- Payment Optimisation — traced checkout drop-off and reworked the flow with sales and finance, lifting conversion by ~6%.
- Game Design — co-designed the "Trash Bin Battle" AI mini-game, from mechanics to tested prototypes.
