Exhibit C — Procedure

Four steps. Nothing skipped.

Every file follows the same checklist, start to close.

1

Discover

We map your business, users, and goals — then scope requirements and risks before any code is written.

2

Design

Wireframes become clickable prototypes. We validate ideas early, while changes are still cheap.

3

Build

Two-week sprints, live demos, clean code, and automated testing at every checkpoint.

4

Ship

Store submission, production deploy, analytics — then we iterate based on real data.

Exhibit D — Toolkit

Evidence of good tools.

Chosen for the long run — performance, reliability, a codebase you can own.
