What I'm Building

Sanitized notes on current builds. No live system details, no screenshots of real data. Architecture diagrams only.

Private AI for Business Operations

Status: active build

A local AI system running entirely on on-premises hardware that handles lease document analysis, financial reconciliation, and investment research for my businesses. No data leaves the machine.

The stack is a consumer GPU (RTX 3060, 12 GB VRAM) running quantized open models, a retrieval layer on top of the document store, and a set of task-specific workflows for finance and property operations. The whole system sits behind a private network with no cloud egress.

I write about what I build and what breaks on the Local AI notes thread.

ASEAN Property and SME Portfolio

Status: ongoing operations

An active portfolio of property investments and asset-backed SME positions across Singapore and Malaysia, with selective ASEAN exposure. Running these as an operator, not a passive investor, which means being involved in the underlying businesses.

I write about the investment thesis, specific market observations, and what running these businesses teaches you about capital risk on the Investing thread.

Home Lab, Locked Under a Desk

Status: designed in 3D, parts being chosen

Every machine that runs the AI work, consolidated into one locked, ventilated cabinet under a desk, safe from small hands. Before buying anything, I had two local models build the whole setup in 3D so I could check every fit, cable and airflow path.

See it in 3D, and what the models got wrong

Open the cabinet, slide the PC out of the rack, and compare the two models' work side by side.
