Building systems that reason and remember
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
ACTIVEAn 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.
Pix
Hackathon WinnerAn autonomous oracle agent on Twitter. Performs I-Ching readings and stores insights on OriginTrail's decentralized knowledge graph. Won Consensus HK 2025.
Content Engine
ACTIVEFull-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.

Augustin Chan
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.
