About
Robert Brennan
Founder, Qi Machine LLC
10+ years

I've spent over a decade building software across mobile, web, and enterprise - working with startups, small businesses, and larger organizations that need a senior technical partner, not a vendor.

My work divides into two areas: products I build and publish myself (the apps in my portfolio are mine - I design, build, and maintain them), and contract engagements where I embed with a client to build something specific. Same skills, same attention to detail, different context.

AI is changing what's possible in software right now. I can build AI-powered systems for your business, or give you a straight assessment of what's actually useful versus what's hype.
