Building

I’m Johan Sammy — a sustainable-mobility advocate and thought leader turned builder. For over a decade I’ve championed car-lite, low-carbon cities across Southeast Asia — advising city governments, speaking, and helping bring shared-mobility services to the region. Along the way I taught myself to ship software, and today I design and run production AI systems end-to-end.

This is where I write about what I’m building.

Tapak — a preliminary low-carbon read for any Malaysian site

A tool that turns an uploaded map screenshot into a preliminary, LCCF-aligned low-carbon reading of a Malaysian site. It cites the gazetted plan and links to PLANMalaysia’s I-Plan to verify — preliminary, never official; reference-only by design. Early, and being built in the open.

The Core — an internal project & resource platform, with an AI layer

A multi-user production application a real team uses every day: project and resource management with an agentic chat layer over live operational data, plus presence and version-adoption tracking, all on self-hosted, cost-engineered infrastructure. My proof that I ship and operate real software, not just prototypes.

Also on the workbench

• A multi-provider terminal LLM CLI with an agent mode — one tool, many model providers, routed for cost.
• Trading-intelligence bots — LLM-assisted market and filing scans that do real daily work.
• Assorted automation — self-hosted, lean, and built to run unattended.
