// who's behind it

35 years of shipping, now with AI on the team.

I'm Simon Filtness. I've built software for over 35 years, and now I use Claude Code to deliver in a fraction of the time. Same engineering judgment, far less waiting around.

For you that means real work handed off to someone who's seen the failure modes before, moving at the pace AI makes possible.
