Joseph Puglisi Custom software for businesses
Software that fits how your business runs
Operations apps, field apps, customer portals. And AI that asks before it acts.
Four parts, one system: the kind I build. Try the one on top.
A diagram of one system in four layers: an operations app, a field app, a customer portal, and on top an assistant that asks before it changes the schedule. You can approve its suggestion and undo it.

Office, field, and customer apps connected into one system, like Cannonball.

“Off-the-shelf software almost fits. We work around it every day.”
What I build
Software shaped around how you actually work, not the other way around.

How it works
A 20-minute call
Tell me what’s slow, manual, or broken. I’ll tell you honestly whether I’m the right fit.
A clear plan
If it’s a fit, I send a written proposal: what gets built first, what it costs, and when you’ll see it.
Working software, early
Built in phases so you see real progress quickly. You own the code. After launch, I stay on for fixes and changes on a simple monthly plan.
I’m Joe. I’ve spent 20+ years making complicated things work.
I’ve led engineering teams and built everything from low-latency financial systems to mobile apps. These days, I bring that experience to custom software and AI projects.
I’m a software architect and former engineering director, with a background in FPGA and Linux kernel software and platforms processing millions of messages a day. And that’s Turing. He gets the sunny spot.
