35 years as an aerospace engineer. Now building apps solo,
one App Store release at a time.

From launch pads to launch days

The short version of a long career change.

I spent 35 years as an aerospace engineer — first at Ford Aerospace, then three decades at NASA — before software became the thing I wanted to build with my own hands. These days I design, code, and ship iOS apps under MarkWare LLC — everything from restaurant- and TV-decision tools to retro arcade throwbacks and an original 3D shooter.

No studio, no publisher — just me, shipping things I'd want to use myself.

Questions, feedback, or just want to talk shop.

I also occasionally take on custom app development for outside clients. If you've got an idea you'd like assessed, costed, or turned into a proposal, send me a message — the more concrete you can be up front (clear use-cases, a rough UI sketch, anything that pins down the idea) the faster I can turn around a real answer instead of a guess.
