Building systems that reason and remember

Informatica · APAC/EMEAUC San Diego · Bronx HS of ScienceConsensus HK 2025 Winner

REASON

DSPy optimization, RAG pipelines, agent orchestration. Making LLMs do useful work reliably.

  • >Prompt optimization & evaluation
  • >Content generation pipelines
  • >Autonomous agent workflows

REMEMBER

Postgres-native architectures. pgvector, JSONB, semantic search without separate vector or graph DBs.

  • >Vector embeddings in Postgres
  • >Event-sourced state & temporal queries
  • >JSONB for flexible metadata

What I'm Working On

8-Bit Oracle

ACTIVE

An I-Ching oracle that remembers your journey. Building the memory layer now—events, claims, confidence evolution. The kind of AI that develops a relationship with you over time.

Currently implementing: bi-temporal validity, budget-constrained retrieval, and the “oracle knows you” experience.

Hackathon Winner

An autonomous oracle agent on Twitter. Performs I-Ching readings and stores insights on OriginTrail's decentralized knowledge graph. Won Consensus HK 2025.

Content Engine

ACTIVE

Full-stack content generation system. DSPy-powered pipelines, MCP agent orchestration, research paper ingestion. All backed by Postgres with pgvector for semantic search.

Processing orchestrator patterns, audit wrappers, content variety scoring, model registry for A/B testing.

Also: ZK proofs for verifiable I-Ching, passkey auth, and various attempts at making machines more human.

Before AI, I spent 10 years at Informatica building master data management systems for enterprises across APAC and Europe. Large-scale data architecture, complex integrations, the kind of work where you learn that systems need to be robust before they can be clever.

Now I apply that discipline to AI: prompt optimization with DSPy, production agent orchestration, memory systems that let LLMs maintain context across sessions. The engineering that makes AI useful for users.
