Shipped iOS product
Algorithm Visualizer
An interactive iPhone and iPad learning experience that turns binary heaps and sorting algorithms into direct manipulation and visual feedback.
// PROGRESSIVE 3D SYSTEM
The work remains accessible without WebGL. Enter the scene on a capable desktop, or open any verified mission directly.
// DERRICK WATSON — ATLANTA, GEORGIA
ACTIVE ENGAGEMENT: [REDACTED] // CLEARANCE REQUIRED
A product-minded engineer with more than seven years specializing in iOS development and a broader foundation across web engineering, product design, field systems, and AI-assisted delivery. Derrick builds software that turns complicated workflows into direct, human experiences.
// RELEASE-BACKED BUILD LOG
This log is built from the same dated App Store evidence used by the case files. It does not invent deploy activity.
// MISSION INDEX
The tactical interface is the frame, not the evidence. Every mission resolves to a shipped product, documented role, demonstrated capability, or direct contact path.
// VERIFIED OUTPUT
The case files separate the user problem, Derrick's contribution, the technology, and the externally verifiable outcome.

Shipped iOS product
A focused weather application designed to answer the immediate question—what does it feel like outside?—without burying the user in instruments.
AI-enabled full-stack lab
This portfolio itself is an engineering case study: a static-first recruiter experience progressively enhanced with an accessible real-time 3D system.
// NATIVE SYSTEMS
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.
