Katie builds custom software, mobile apps, web apps, and AI-powered tools for operators who've outgrown off-the-shelf solutions. Not a dev shop — a single expert who owns the full stack.
Purpose-built tools for how you actually work — not shelf software jammed into your process.
iOS and Android apps built for real-world operator use — not App-Store theater.
Dashboards, portals, booking systems, internal tools — if it runs in a browser, it belongs here.
AI that actually runs your workflows — not a chatbot bolted onto a slow process.
Text PJ with a one-line description of what you want to build. Katie will respond with a plain-language scoping draft — no pitch deck, no sales call.
