In production
Software that's actually shipped.

What I build
Full-stack development, end to end.
Every capability below is in production today — in apps live on the App Store and tools in daily business use. Design, front end, back end, and the AI in between are built as one system, so the parts actually fit.
Under the hood: 258/258 tests on the last build · deny-by-default security · zero advisor findings.
Mobile apps, shipped
iOS · React Native · EAS
Native iOS apps taken from the first sketch to a live App Store listing — designed, built, submitted, and through Apple review. I ship to the store from a Windows machine, so there's no studio required behind the work.
Web apps & dashboards
Next.js · React
Admin consoles, operational dashboards, and internal tools built around how your team actually works — the screens people open every day and don't fight with.
Backends that hold up
Supabase · Postgres
The part most people cut corners on: real databases with locked-down access and test coverage behind every feature, so the product doesn't buckle the first time it's used for real.
AI that does the work
OpenAI · Gemini
Real-time voice, photo and vision analysis, and AI-generated documents — wired into the product to do a real job, not a demo that impresses once and gets switched off.
Automation that removes steps
APIs · pipelines
The manual, repeatable work eating your week — turned into software that just does it, end to end, and hands back the finished result.
Design & UX
custom interface systems
An interface that looks like your business and feels considered — a real design system, not a template with your logo dropped on top.

Process
How an idea becomes a shipped product
Free assessment
Tell me what's not working. Within two business days you get my honest read: fit, risks, and the best next step — whether or not that step is me.
Scoped proposal
A written proposal with the full scope and a fixed price — you know exactly what Version 1.0 is and what it costs before anything starts.
Build in milestones
You see working software as it lands. Billing follows delivered milestones, not hours.
Ship + hand over
App Store submission, handoff docs you can actually use, and full ownership transferred to you — code, data, and accounts. First year of on-call support included.
Tell me what's slowing the business down.
A free assessment comes back within two business days: fit, risks, and the best next step.
About
A developer who ships production software
I'm Paul Corriveau. I build full-stack software end to end — native iOS apps, web platforms, production backends, and AI integrations — and I've put it on the App Store and into weekly business use. I'm self-taught and serious about the craft: I go deep on new technology because I'm genuinely driven by it, and I hold every build to production standards, not demo standards. PhattCorp is how I bring that to other businesses — based in Boston, working with businesses anywhere.
