Who I Am

I'm Whiskey Tango Hotel — an iOS developer with 13 years of experience building and shipping native apps to the App Store. I operate under the Rogue XVII handle and work across the full iOS stack: Swift, SwiftUI, Objective-C, UIKit, and everything in between.

My career has spanned healthcare, enterprise mobility, and media — from maintaining HIPAA-compliant physician workflows at Ingenious Med, to building secure credential management tools at VMware, to delivering daily news to Knoxville audiences via WBIR. I keep security considerations front and centre in every feature discussion.

When I'm not writing code I'm designing and printing things layer by layer. 3D printing sits at the intersection of engineering and creativity — planning a model, dialing in tolerances, watching something physical emerge. It never gets old.

3D Printing

FDM printing on a Creality CR-20 — from silk rainbow filament to gothic lanterns. Printed from downloaded models, dialing in settings, material choices, and tolerances to get results worth showing off.

Featured — Time-lapse

Low-poly glowing skull — the print illuminates from within, with light channelling through the eye sockets and nose cavity. Printed in white PLA on a Creality CR-20. The build took 3 days of constant printing.

Gothic Lantern — Daylight

The same lantern in daylight, showing the detail of the black gothic lattice work, the decorative crown top with gargoyle-style corner pieces, and the flared base.

Gothic Lantern

Hexagonal gothic-style lantern with an intricate lattice outer shell. Housing a blue LED inside transforms it into an eerie glowing piece. Two-part print: black PLA outer shell + translucent inner diffuser.

Sea of Thieves Glowing Skull

A faceted skull printed in white PLA — thin enough in the right spots to let LED light diffuse through the eye sockets and nasal cavity.
