I still write and ship code. Cinch, a multi-tenant collaboration platform running in production at cinchme.app, is the clearest example of how I think an engineering organization should work: tenant isolation enforced in the database and proven against disposable instances, a browser suite that runs against the production image rather than a mocked frontend, and a release that will not promote traffic until health checks and an SBOM-backed image policy pass. None of that is exotic. It is simply refusing to let ambition outrun proof.
The other half of the CTO job is deciding what not to build. Cinch uses a managed media provider instead of running its own global network, keeps the real-time sync tier untouched on routine releases, and records every durable decision in an ADR so the reasoning survives the people who made it. At North Highland the same instinct produced an AI-assisted product development method that cut cost and time to market by more than 90%. Good engineering leadership is mostly about boundaries.
