Public artifacts, generated from evidence.

This log is built from the same dated App Store evidence used by the case files. It does not invent deploy activity.

Seven doors. Every one leads to real work.

The tactical interface is the frame, not the evidence. Every mission resolves to a shipped product, documented role, demonstrated capability, or direct contact path.

Products and systems with proof attached.

The case files separate the user problem, Derrick's contribution, the technology, and the externally verifiable outcome.

Deep mobile craft. Expanding delivery range.

Derrick's foundation is native iOS product engineering: secure user flows, maintainable architecture, analytics, beta delivery, and interfaces built for real operating contexts. React, Node.js, TypeScript, design, and AI-assisted development extend that foundation without pretending every tool represents the same depth.
