A mix of everything.
A label for none of it.

Rojak is a Southeast Asian dish — fruit, vegetables, dough fritters, tossed in a thick, dark sauce. No rules. Everything belongs. That's this place.

A homelab that doubles as a product studio, where trading bots run on the same machine as family trip planners — and where AI writes the code while curiosity writes the brief. No job title required.

Every project here was built in the margins of a day job — evenings, weekends, one problem at a time. Powered by Claude, containerised with Docker, deployed on a Synology NAS, and routed through Cloudflare. Quietly running from a home rack in Singapore.

Alpaca Trading Bot

A composite trading system for US equities. Six strategies vote through a scoring engine; a trade fires only when conviction clears the bar. Institutional risk primitives — Triple Barrier exits, fractional Kelly sizing, ADX regime detection — all wrapped in a single Docker container.

OKX Momentum Bot

A spot-only momentum bot scanning 12 USDT pairs every five minutes. Three indicators vote — RSI, EMA cross, MACD — and a BTC 4-hour regime filter retunes thresholds on the fly. Half-Kelly sizing, a six-trigger triple-barrier exit, and a Bloomberg-style terminal. Runs 24/7 in Docker on the NAS.

A line-by-line quotation builder for renovation and interior-design work. Pull items from a 31-row catalog, group them by trade, and tune markup, GST and discount on the fly — every unit cost rolls up to a live total and a clean, client-facing PDF.
