ABOUT

Thirty years of building things that ship.

I've been writing software since the mid-90s — a career that spans enterprise systems, web platforms, mobile apps, and now indie games. I ship code that runs in the real world, under real load, for real users.

My background covers backend architecture, cloud infrastructure, product engineering and mobile. When I'm not working on client systems, I'm building Stellar Invasion — a Swift + SpriteKit tower-defence game for iOS & iPadOS.

CURRENT PROJECT

Stellar Invasion — defend the solar system, one planet at a time.

A cinematic tower-defence game for iOS & iPad. 13 hand-designed maps from Proxima Centauri to Earth, cinematic defeat sequences, 13 tower types, and a superweapon system that recharges as you play.

13 unique maps

Every planet has its own path design, tower slots, enemy pool and boss. From Alpha Centauri all the way home to Earth.

Cinematic defeats

Lose the last three levels and watch Earth burn. Lose Mars and it's gone too. Every campaign has stakes.

13 tower types

Cannon, laser, missile, tesla, cryo, plasma — each with three upgrade tiers and their own tactical trade-offs.

Superweapon

One per map, charges as you play. Save it for the wave that would have finished you off.

iPhone & iPad

Fully adaptive layout — designed for iPhone in your hand and iPad on the couch.

Endless mode

Finish the campaign and unlock Endless — one map, infinite waves, one leaderboard.
