Work
Systems I've built and run.
Written up as deep dives: what was broken, what I built, and the decision that was actually hard.
Loam
A markdown app for the agent era with no AI inside it, built around a press that produces byte-identical HTML on any machine.

The billing platform
A billing system built on one split — the number that bills is never the number that merely displays — and the audit of my own dashboard that proved the invoice had been right the whole time.

A cold-email sequencer in 512 lines
Gmail and a Google Sheet doing the job of a seat-priced sales tool, where the hard part turned out to be deliverability rather than sending.

WealthLens
A goal planner is a compounding calculator wearing a UI, and the honest version of that UI has to admit what the calculator doesn't know.

Reworking a 3.1/10 frontend
A v1-to-v2 rework where the reasoning was written down before the pixels moved, and where the migration stalled one phase short, for a reason worth reading.

The prototype that became the spec
A policy-management prototype for banks where every trust-critical decision was moved out of the model and into architecture, which is why there's no confidence score in the codebase.

The metric the dashboard refuses to show
An engineering-management dashboard whose defining constraint was a policy: individual metrics are self-service only, never leadership-visible, enforced in the data layer rather than the UI.

A CRM compiled to a single HTML file
A pipeline dashboard that started as one static file with the data baked in, and whose most useful view audits the pipeline's integrity instead of reporting its size.
